CMS HCAL Radioactive Source Mover


CMS HCAL Radioactive Source Mover should perform the following tasks:

  1. Operate the commutator to select a destination

  2. Operate the motor drive to position the source

  3. Monitor status of operating parameters

  4. Readout the source position transducer

  5. Service external requests for commands, status and position readings
This system is a state machine coupled with a few IO peripherals and a network connection. Interconnections with the source mover are hard wired.


How to achieve this?



A stand-alone system exists. Its schematic view is shown here:


The target system should look something like:

Like with the laser system, we want to reuse the existing driver and decouple the system modules as much as possible.
