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
K. Gnanvo - RD51 Mini Week, CERN January 2011
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

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
