DATE Framework with UDP equipment for the SRS Data Acquisition

(Filippo Costa, ALICE DAQ)

DATE: ALICE DAQ software Data Acquisition & Test Environment on Linux SLC5 Many features available , user friendly GUI for run control environment,

basic online monitoring of the raw data, electronic logbook.

Data transfer to the DATE PC through Gigabit Ethernet via UDP: One Ethernet port on the FE card connected to another port on the DATE PC

via a copper cable or optical fiber cable data, (1Gb/s to 10 Gb/s throughput) Network switch to handles as many as the 8 UDP ports for MT application

“Slow Control” for the system configuration C script for Initialization of the FEC, ADC boards, APV hybrids and the

network configuration …, uploaded at the Start of Run of DATE

AMORE for monitoring and data analysis

AMORE is ALICE Data Quality Monitoring Software framework

Automatic MonitoRing Environment founded on ROOT & DATE Monitoring Library

Online monitoring and offline data analysis (pedestal subtraction, zero suppression, strip occupancy, spectrum …)

amoreMTS package developed for FIT Muon Tomography Station, suitable for any application using the SRS electronics with APV Pedestal run, test characterization run & more specifically Muon Tomography run

Baseline correction & pedestals

1 step: computation of raw pedestal data to correct the baseline fluctuation

2nd step: common mode offset calculated for each time frame for each event from raw pedestals
