5. 20/10/2008A. Alici - ALICE TOF Festival5 TDC Readout Module piggy-back card (3 HPTDC chips) Each TRM boards houses 30 HPTDC ASIC and 10 temperature sensors on 10 piggy back boards. multi-hit and multi events capability 240 channel with 25 ps resolution

6. 20/10/2008A. Alici - ALICE TOF Festival6 Data Readout Module (DRM) The DRM provides the VME Master duties in the crate (data readout from TRM boards) and performs other functions, such as: data transmission and communication with the ALICE DAQ system through Data Detector Link (DDL) reception and computing of trigger signals through Timing Trigger Control receiver (TTCrx) VME bus access through a slow control optical link remote programming of FPGA on VME boards in the crate

7. 20/10/2008A. Alici - ALICE TOF Festival7 Electronics QA tests Pulser test of SM searching for “dead” and noisy channels: total amount less than 0.5% over the whole TOF (157248 channels)

8. 20/10/2008A. Alici - ALICE TOF Festival8 TOF trigger The MRPC detector provides very fast signals with relatively low noise  TOF can be used as L0 trigger. Several trigger topology selected during cosmics run. The TOF based trigger is a very usefull tool for TOF and other detector commissioning. TOFforTRDBACKtoBACK
