DAQ Status for cosmic-ray test in RAL
Hideyuki Sakamoto
MICE Phone meeting
12th July 2007
Contents• Status• Setup for cosmic-ray test bench • Schedule
Scheme for DAQ
• DATE (Data Acquisition and Test Environment) framework.
• Need to build modified readout program for MICE in DATE.– Other part (e.g. data format, eventBuilding) will use default one.
– Readout program is prepared for each modules.• VLSB module made by FNAL
• TDC/ADC module made by CAEN
• Sub-framework (readout+initializing) is under preparing by James.
Status
• New RHB is coming today, taking data with test charge injection/cosmic-ray.– Threshold: 100,120,160,200,240– Bias ON & Heater ON– Try heater current to be low by heating cryostat with OXFORD temperature controller.
• Started working on DATE from last week.– Yesterday, once success to starting readout program in DATE.
…fail at 2nd try…– Should be finished in next week at RAL.
• Readout code is under implementing.– Sub-framework is almost done?– Command lists are replaced from AFEII to AFEIIt.
– Can be tested at stand alone.– Linux driver for SBS(bit3) dataBLIZZARD to test in Imperial.– In next week, test will also be done in RAL.. (using CAEN)
Threshold 100It seems LHB RHB compared with previous version for Excel sheet.
Threshold 120Increase noise
Threshold 160Increase noise
Threshold 200Decrease noise
Threshold 240Decrease/Same? noise
Bias ON - threshold 160 - w/o charge injection

Comment for today’s result
• Noise rate seems to be reproduced as previous RHB.
• Noise rate seems to be reversed at threshold 160 by eye.– This may not true.
• For treatment of heater current, it is better to compare with the same RHB, so taking data with default setting with this new RHB.
Possible reason for RHB noise
• Remember that we do not see ANY noise with test charge injection data.
• Let’s check this fact by taking data as changing triggering rate.– This will be done by LED pulse injection.
– If we take data with high rate, we cannot not see any noise as LED data.
– It not, there is problem at the setting of self trigger mode.
• Our goal is to identify/remove the noise.– If heater current is the reason, then we should see any changeable results
from it.
– We should check it by taking data with the default setting as previous.

Slow progress for DATE
Last week Yesterday Goal in RAL?
Yesterday, reach to goal, but 2nd try was failed….=> finish in next week at RAL!

Check numbers for cosmic-ray test
• 2 VME crates– Slow control will be separated from DAQ crate.
• 8 AFEIIt boards– To readout 5 stations, we need 3200 channels in total.
• 8 VLSB modules– 1 VLSB is needed to readout 1 AFE board
• 1 ADC & TDC module– Used for readout defining counter
To readout 5 stations….

3200(640 x5) channels for VLSB

8 AFEIIt boards = 8 VLSB modules
How about VLSB modules?This cabling is virtual.

Schedule
• This week (~13th)– Checking signals for newly RHB today!
– Testing code for VLSB module in Imeprial.• Waiting for driver for SBS(Bit3) dataBLIZZARD.
– Implement readout code for new firmware (ce).
• Next week (16th ~ 20th)– Set up test bench at R12 in RAL with JSG/Mike/Nicholls/Craig/etc.
• Clone system for Geneva University
– Testing code for CAEN modules(V977, V1270, V1724) in RAL.
– To test VLSB modules in RAL, need more modules! Please send to RAL!• Imperial’s VLSB will be in use for QA.
• The week after next (23rd ~ 27th)– DAQ workshop (23,24,25)
– Finish to setup DAQ system (mainly to debug readout program, I think)
R12Here coming 2 cryostats & 1 compressor & 1 transformer & 8 AFE boards & 5 stations & 25 inter/external waveguides & 1 patch panel & 2 VME crates & 2 NIM crates & VME/NIM modules & 2 DAQ PCs & other stuff…
