CMS HCAL Charge Injection System


CMS HCAL charge injection system should perform the following tasks:

  1. Load revolution and bunch counters for timing control

  2. Control the on/off status bit

  3. Provide readback of the counters and status bit
This system is a non-intelligent control interface for charge injection functions distributed at about 150 HCAL locations. Loading and retrieving information is via a radiation tolerant fieldbus network.
