  1. Experience with SRS and APV Readout of Triple-GEM chambers For Muon Tomography Kondo GNANVO Florida Institute of Technology, Melbourne FL

  2. OUTLINE • Development of AMORE software for online monitoring and data analysis of MT station • Preliminary cosmic data results from triple-GEM chambers with APV/SRS electronics • Plans for the next MT station prototype with full APV/SRS readout electronics • Conclusion K. Gnanvo - RD51 Mini Week, CERN January 2011

  3. First Test of the SRS Electronics with triple-GEMs For RD51 Coll. Meeting, Bari, Oct. 2010 ADC/FEC card in Euro crate Triple-GEM with 12 APV hybrids Plastic scintillator for trigger ALICE DATE for the DAQ AMORE for online monitoring K. Gnanvo - RD51 Mini Week, CERN January 2011

  4. 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

  5. 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 K. Gnanvo - RD51 Mini Week, CERN January 2011

  7. Preliminary cosmic data results with triple GEM chambers with APV/SRS electronics Triple GEM with 12 APV hybrids • Five 30 cm x 30 cm triple-GEMs • Pedestal run 20K events • Cosmic data run (20K events) • 12 APV hybrids (5 hybrids v1 and 7 hybrids v2) • On X-strips: 5 v1 and 1 v2 • On Y-strips: 6 paired on a master/slave (M/S) configuration • The hybrids not grounded to the detector M: Master hybrid S: Slave hybrid Blue: hybrid v1 Red: hybrid v2 M S M 768 X-Strips M M M 768 Y-Strips M S M S M S K.

  14. 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 Front-end cards GEM support (with cut-out) GEM detector active area Target plate HV board K. Gnanvo - RD51 Mini Week, CERN January 2011

  15. Plans for the next MT station prototype with full APV/SRS readout electronics • 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

  16. 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 K.
