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
