Tile Calorimeter

Interface Board

Overview
Specifications(Version 0.99) as supplied for summer '00 test beam.
Results from CERN test of Nov. '00
- Response to fixed CIS signal for 48 channels (high gain). Three channels from one digitizer Tile DMU chip have a large pedestal and three channels are unused. The labeling of two unused channels is shifted by one because of a minor firmware problem.
- Pedestal for 48 channels (high gain, low gain)
- System noise for 48 channels. The "high frequency noise" corresponds to the RMS of the 9 pedestal samples within an event. The "low frequency noise" corresponds to the pedestal variation from event to event.
Radiation requirements
- Simulated radiation levels over 10 years at z=150 cm, as of 11/18/00
