#$KIntroduction
Hardware
The Universal Computer Spectrometer offers a unique solution for nuclear spectrometry using the PC platform. A 2K ADC combined with 8K of data memory and multi-channel scaling is ideally suited to scintillation spectroscopy and time related studies such as half-life decay.
Constructed in a sturdy, fully-shielded bench top enclosure with Universal Serial Bus (USB) computer interface, the multi channel analyzer contains many advanced features including computer controlled amplifier and high voltage for PM tubes, upper and lower level discriminators, on instrument data memory, and a comprehensive software package for use under Windows 98 or higher. (Windows 95 may be used if you have installed the USB patch.)
The UCS-20 requires only an available USB port and is designed to work seamlessly with USB-equipped PCs. For stability and low noise operation, the unit is AC-line powered with an auto-sensing power supply for 100-250 VAC operation. An on-board microprocessor acts as the master controller and data storage device, as well as the communication link directly to the USB interface.
The integrated amplifier and high voltage are fully compatible with most standard scintillation detectors, eliminating the need for special tube bases and external modules. For ease of setup and calibration, coarse gain, fine gain, high voltage, and lower and upper level discriminator settings are controlled directly from the desktop computer. For operation with other types of detector systems such as alpha spectrometers or single photon counting, a DIRECT input is provided to bypass the scintillation amplifier and allow direct access to the ADC.
A 2048 channel ADC with de-randomizing buffer offers excellent data throughput at high counting rates with minimal dead-time losses. Conversion gain may be changed from 2048 to 1024 to 512 or 256 channels via the software. Data from the ADC is stored directly in on-board memory for autonomy and high-speed operation, freeing the host computer for other tasks.
Software
The UCS-20 produces a high-resolution, real-time live color display of spectral data with standard PC graphics running under Windows (95 and above). Operation is intuitive
#IDH_INTRODUCTION $Introduction KIntroduction
using pull-down menus and function buttons for the most commonly used commands and display options. The software offers full control of all features including preset live/real time, and regions-of-interest together with centroid, gross and net area calculations.
Control of the hardware amplifier, high voltage, ADC and input discriminators is also through function buttons for straightforward calibration and operation. To simplify identification of peaks, the cursor may be calibrated to read directly in energy units, using either a 2-point linear, or 3-point quadratic relationship to allow for detector non-linearity.
Spectral files may be transferred to disk for long-term storage as binary files or transferred through the clipboard in ASCII format for exporting to other programs. Stored files may be used to collect background data over a long counting period that can be subtracted on a time proportional basis from the spectral data.
To aid in the identification of nuclides, the UCS-20 contains a unique peak-labeling feature named ISOMATCH. Providing the unit is accurately energy calibrated, the user may select a nuclide from the library and the corresponding characteristic emission lines are superimposed on the spectrum along with isotope and energy information. Using this feature, users may quickly check a spectrum and visually identify the emission components for each nuclide present. The ISOMATCH libraries may be created or customized using a text editor.
When operating in multi channel scaling mode, the system may be calibrated in time units for direct readout from the cursor.
Both linear and logarithmic vertical display ranges are included which can be useful when performing decay studies
Spectrum files, can be transferred from the ICS 10 DOS program and the ICSW 16 Windows program to the UCS20 Windows version. Most functions may be accessed by more than one method. All the functions can be accessed from the Pull Down Menu, some from the Tool Bar Buttons, or by the mouse. If the function has a Tool Bar Button, its symbol will be shown on the left hand side of the description.

#$KInstallation System Requirements The UCS20 instrument uses a Universal Serial Bus (USB) to communicate with a PC. The PC must have USB compatible drivers, which are available standard on Windows 98 and later releases. Windows 95 must have the USB upgrade or patch to work. The performance of the USB on older systems may affect the perceived performance of the software; so we recommend that you use a Pentium 2 or greater class of microprocessor running at 250 mHz or greater to achieve desirable performance. The executable code is less than 600 kb, but the help files are more than 5 mb; so if you have limited disk space, you may wish to leave the help files on the CD.

#$KAnalysis Modes
See:
Pulse Height Analysis Multi Channel Scaling External Multi Channel Scaling
#IDH_MODES $Analysis Modes KAnalysis Modes
#$KPulse Height Analysis
This is the normal operating mode for collecting sample gamma emission spectra. The amplitude of each detector pulse is measured by the ADC and stored as an amplitude (energy) spectrum. The X axis is scaled to the selected channels and the Y axis is scaled for the counts for each channel. Y axis counts that exceed the maximum Y axis value are ‘wrapped’, they no longer are scaled to the Y axis, and they appear in a different color.
#IDH_MODESPHA $Pulse Height Analysis KPulse Height Analysis
#$KMulti Channel Scaling
Multi Channel Scaling mode is used for measuring time related phenomena such as half-life decay or single photon counting. The ADC is bypassed and incoming events are routed directly into memory for specific predetermined times (dwell time) and stored in sequential memory locations. To use this mode, first acquire a spectrum using the Pulse Height Analysis mode. While acquiring the spectrum, adjust the LLD and the ULD to select the energy range of interest (for example, selecting only the 662 keV peak form CS-137 can eliminate unwanted background and produce a superior decay curve when using a Cs-137/Ba-137 mini-generator.)
Click the Mode menu and select MCS #IDH_MODESMCS $Multi Channel Scaling KMulti Channel Scaling
Click the Settings menu and select MCS
Enter the Dwell Time. This time is for each memory location (channel). Remember the total pass time will be (Conversion Gain x Dwell Time). Erase any current memory data and click start. The UCS20 will proceed to count incoming events for the selected dwell time, store the total in the first channel location, reset the counter and repeat the cycle storing each total in sequential channels.
#$KExternal Multi Channel Scaling
If you wish to use an external pulse generation system such as a coincidence circuit, it will be necessary to bypass the on-board amplifier and discriminators. Connect the external counts connector to the Ext MCS connector on the back of the instrument and select the menu item MODE then select External MCS. When operating in this mode, the MCS input requires positive TTL signals (>2.5v, >150 ns duration).

The Amp/HV/ADC dialog box will appear. Adjustments may be made to the amplification, high voltage, conversion gain, low level discriminator, and the high level discriminator. #IDH_SETTINGSAMP/HV/ADC $Amp/HV/ADC KAmp/HV/ADC
Selecting OK will cause these values to be written to the UCS20 instrument. Configuring System Parameters: Once the program is running it will be necessary to configure the system parameters for correct operation and calibration. Place a gamma emitting check source near the detector face. Cesium-137 (Cs-137) is a good choice. It has single peak at 662 keV. Click on Settings, then click on Amp/HV/ADC Set the high voltage to the voltage as listed by the detector manufacturer. As an example, set the high voltage to 600 volts, click ON. DO NOT exceed the maximum high voltage rating of the detector, usually 1200 volts. Set the amplifier COARSE GAIN to 8, and set the FINE GAIN to 1 as a starting position. Click on OK, to set adjustments and exit the menu. Start the data acquisition and adjust the amplifier gain until the 662 keV peak is approximately mid-scale. Once the acquisition is started, you may enter the Amp/HV/ADC menu, make adjustments while viewing the spectrum. This will allow you to position the peak in the desired channels.

#$KHigh Voltage
High Voltage may be entered directly in the text box or may be scrolled to the value desired. A warning will be issued if you attempt to input a value higher than 1200 volts, since this is the highest value that many probes can tolerate without damage. If you know that your probe can accept higher than 1200 volts, you may increase the voltage up to 2500 volts. See also:

#$KADC Conversion Gain
Conversion Gain represents the number of channels that will be sampled and displayed on the screen. Smaller values save as smaller files The conversion gain default setting is 1024 channels. This is preferred for most scintillation detector applications and generally no adjustment is required. For certain applications, such as alpha spectroscopy, it may be necessary to change this parameter to either 256, 512, or 2048 channels. See also:

#IDH_SETTINGSADCCONVERSIONGAIN $ADC Conversion Gain KADC Conversion Gain
#$KLower and Upper Level Discriminators
LLD and ULD, Lower Level Discriminator, and Upper Level Discriminator, allow the user to set a value between 0 and 106 (roughly percent) that cuts off signal before it gets to the ADC. The LLD is often used to block high-count signals in the low range that are not of interest, but require excessive time to sample. The ULD may be set up to 106. Low level discrimination (LLD) may be scrolled or directly entered. Upper level discrimination (ULD) may be scrolled or directly entered.
An alternative method to change the LLD and ULD is to use the mouse to move the triangles under the X axis. Move the mouse over the triangle to be moved, press the left button, drag the triangle and release it where desired. The software will not allow the LLD and the ULD set outside appropriate ranges.

Click the Preset Integral Button on the toolbar:
Or use the settings menu and click on Presets For details see:
Preset Time Preset Integral
# IDH_PRESETS $Presets KPresets
#$KPreset Time
Preset Live Time provides automatic correction for counting losses caused by the system deadtime. Events which occur during the pulse processing cycle are lost to the system so the timer is automatically updated to compensate for these losses. When operating at excessively high count-rates the deadtime meter will indicate a high value and the real counting time may be more than doubled. Increasing the LLD setting can help reduce some high deadtime effects. Preset Real Time sets the counting timer to run for actual clocktime and makes no correction for losses due to deadtime effects. Click on Settings, click on Presets Enter the LIVE or REAL time in the correct box. Click on OK, to set adjustment and exit menu.
Both the LIVE TIME and REAL TIME values are displayed on the UCS20 status bar as LT and RT. These values are saved in the file during data storage.
#IDH_OPPRESETTIME $Preset Time KPreset Time
#$KPreset Integral
Set Integral To set an integral count it is necessary to first establish a ROI and then position the marker within the region. Selecting an ROI and setting a value other than 0 in preset integral will cause the system to STOP counting when the total of all the channels within the ROI reaches that value.
#IDH_OPPRESETINTEGRAL $Preset Integral KPreset Integral
#$KGo, Stop and Erase
Go, Stop and Erase functions are accessed with the Tool Bar buttons. Clicking on Start begins data collection. Clicking on Stop ends data collection. Clicking on Erase sets each channel’s data to zero.
#IDH_OPSTARTETC $Go, Stop, and Erase KGo, Stop, and Erase
#$KRegion of Interest (ROI)
Region of interest (ROI) selection is an advanced feature which provides instantaneous computation of peak gross and net counts. These values may be used along with isotope decay tables and detection efficiency to calculate absolute or relative isotopic activities. ROI’s must not overlap and need to be separated by at least one channel for correct area calculation. Up to 16 different ROI’s are possible using the color selector from the pull down Settings menu.
Set ROI To set an ROI around a peak, click the ROI button on the Tool Bar. Click the left mouse button at the beginning of the ROI, hold down the left mouse button and drag the marker to the other side of the peak, release mouse button. Clear ROI Move marker to the ROI to be cleared. Open the Setting Menu, open ROI and select Clear ROI. Gross and Net Count When the marker is positioned in a region of interest (ROI), the UCS20 software automatically calculates the Gross and Net area of the region. In order to minimize statistical effects at the ROI endpoints, a 3-point averaging technique is applied. The contents of channels (n-1), (n), and (n+1) are summed and averaged to derive the content of the endpoint channel for the net area computation. A linear interpolation is performed between these averaged endpoint values and counts below this interpolation are #IDH_OPROI $Region Of Interest KRegion Of Interest
subtracted to arrive at the Net area of the peak. Gross counts is the sum of all channels in the ROI. Position the marker in the peak of interest. The Gross and Net areas are automatically computed and displayed on the spectrum screen.

#IDH_FUNCTIONS $Functions KFunctions
#$KEnergy Calibration
The energy calibration feature allows the marker to read directly in energy units. Two calibration functions are possible, a 2-point linear, or a 3-point quadratic fit. In order to perform an energy calibration, it is first necessary to acquire a spectrum using known isotopes. Cs-137 together with Co-60 works well for many applications, producing gamma lines at 32 keV, 662 keV, 1173 keV and 1332 keV. Select 2-point or 3-point mode and enter the calibration units to be used, (keV or MeV). Position the marker at the highest channel of the first peak and enter the peak energy value. Move the marker to the high point on the second peak to be used for the calibration, enter energy number. If a 3-point calibration is required, continue by moving the marker to the peak channel of the third peak, enter its energy and click OK. The system will now be calibrated and the marker position will read directly in energy. To return to the channel number mode, click on Settings, click on Uncalibrate. Energy Calibration may also be selected using the right mouse button.
#IDH_FUNCENERCAL $Energy Calibration KEnergy Calibration
#$KIsotope Matching
Displaying Isotope Peaks Isotope peaks may be indicated on calibrated spectra. These peaks are selected from a list provided by selecting the Display menu and clicking on Iso Match. The following dialog box will be displayed:
#IDH_FUNCISOMATCH $Isotope Matching KIsotope Matching
Click the isotopes peaks in the left window that you want to display. These will be transferred to the right window. When your list is complete, click Okay to display them. Editing the Iso Match list Select the Edit menu and click Iso Match. The following dialog box will be displayed:
IsoMatch Library NOT loaded. IsoMatch Library IS loaded The dialog box top window labeled ‘Select an existing isotope’ will be empty unless an Iso Match library has been loaded. If a library has been loaded, you can select on of the entries from the window, if a library has not been loaded, or you want to add an entry to
the list, enter the name in the second window titled ‘or enter and isotope name’. Enter the number of peaks you want to add for this isotope in the third box labeled ‘Enter number of peaks [10 max]’ and click on Edit. Further dialog boxes will appear that allow you to enter peak(s) for the isotope.
If you want to save the Iso Match to a disk file, open the File Menu and click on Save Library.
#$KStrip Background
The Strip Background option is available only in the File Mode. The user may load two files (Spectrum and Background) and subtract the second file from the first. The portion subtracted is based on a time adjustment to the data in the second file. For example if the first file was measured with 100 seconds live time and the second file was measured with 200 seconds live time, then the data in the second file is divided by 2 (200 seconds / 100 seconds) before it is subtracted.
Load Spectrum Load Background Show Spectrum Show Background Overlay Spectra Strip Background from Spectrum
Background Subtraction This is a special case of spectrum stripping. Collect a background sample spectrum, usually for a long collection time. Load this spectrum as Background and click on ‘Strip Background from Spectrum.’ The live time fraction of the background is subtracted from spectrum. This provides a convenient method of removing naturally occurring background from a sample spectrum and can be very useful when working with low level environmental samples.
