Development of AMORE Software for Online
Monitoring and Data analysis of MT Station

AMORE is ALICE Data Quality Monitoring Software framework

Automatic Monitoring Environment founded on ROOT & DATE Monitoring Library

It is based on Publisher/Subscriber paradigm with the detectors publishing their data in a
monitoring pool and clients subscribing to the pool to collect data for online monitoring &
offline data analysis.

Communication between publisher and clients through DIM a publish/subscribe system
developed at CERN

Development of AMORE Software for Online
Monitoring and Data analysis of MT Station

First implementation of the software
 used to produce the results for RD51 coll. Meeting in Bari October 2010.

Current version contains the following major improvements:
 Pedestal data are now generated and saved in ROOT files
 Full set of histograms could be generated
 Online monitoring display is implemented and defined via configuration files.

Several Amore Agent to be created for specific tasks (to be done later)
 GEMs testing and commissioning (pedestal data ….)
 Online monitoring of the MT Station with real time targets imaging
 Offline data analysis and saving into ROOT files

Plans for the next MT station prototype with
full APV/SRS readout electronics

Full MT Station
 Cubic-foot size station (30 cm x 30
cm x 30 cm)
 Total of 10 detectors (top and
bottom + lateral station)
 Mechanical stand with flexible
geometry e.g. variable gaps between
detectors
 120 APV v3 hybrids + SRS to read
out more than 15 000 channels
 DATE software for DAQ + AMORE
for data monitoring & analysis

AMORE software development for the MT station
 We plan to integrate POCA reconstruction into the AMORE package
 Online and real time target reconstruction during the data acquisition
 Extend the data analysis code development
 Create task specific AMORE agent
K. Gnanvo - RD51 Mini Week, CERN January 2011
Conclusion

Where we are now:
 AMORE package developed for APV/SRS system for online
monitoring display and data analysis
 Preliminary results from the analysis of cosmic data run with 5
FIT triple-GEMs equipped with APV readout and SRS electronics
 More detailed studies required to understand issues with APV
hybrid v2 pedestal noises

Where we want to be in the next few months:
 Tests of APV v3 hybrids, new generation of FEC/ADC cards.
 Set up the cubic-foot MT station with 10 GEM chambers with
APV/SRS electronics
 Back to DATE software for the SRS DAQ system
 Develop a more robust data analysis and MT reconstruction code
based on AMORE
