CMS HCAL Front End Electronics System


This system should perform the following tasks:

  1. Download CSR information to the front-end channel control ASICs.

  2. Readback CSR information from the front-end channel control ASICs.

  3. Download the embedded microprocessor in the control interface in each front-end electronics enclosure.

  4. Provide limit and alarm functions for temperatures, voltages and currents readback from the front-end electronics enclosures.
This system is a semi-intelligent control and monitor interface for the approximately 150 HCAL front-end electronics locations. Loading and retrieving information is via a radiation tolerant fieldbus network.
