Adders in drawer
Test of TileCal Level 1 Interface
drawer patch panel
trigger cable ca 70 m
receiver
pre-processor
TileCal patch panel
RP patch panel
TileCal Lvl1
The task is to test the information transfer between the TileCal adder boards and the Level 1 preprocessor.
•test the trigger cables
•the receivers
•the patch panel connections
•the pre-processor
Serve as a test bench for the first level trigger.
The tests should preferably also be compatible with the similar LAr tests
MobiDAQ VME test crate developed at CERN to test data from 8 drawers at a time.
MobiTrig We suggest to have a standalone crate to test the trigger signals.
Develop this in Stockholm.
Tests should check for continuity, absence of shorts, cross talk, noise levels, pulse shapes and attenuation.
Components of MobiTrig
• VME-crate (borrow)
• VME processor, CCT (CERN pool?)
• ADC 8 channels, 12 or 14 bits, sampling (borrow?)
• MUX (to be bought)
• TTC receiver module
Functionality
• TCP/IP controlled: initialize, set MUX
• Reports settings and data to COOL (POOL)
• Activated by TTC fiber, L1a
Test environment in Stockholm
Digitizer test bench with adders
Software
• Parts of digitizer test bench s/w, Baltazar
• MobiTrig software (Karl)
• Test data analysis software (ATHENA?) (Elin)
Time scale
• Tests working in Stockholm by July
• Tests at CERN in August
• Massive tests of barrel September - November
• Tests of extended barrels - 2006
