COMICS

Manages the configuration of the detector

Coded in the Python language

Receives sector load requests from COOR A sector is the smallest

detector component managed by COOR

Sectors may be shared by different runs if the sector configurations match

DD

COMICS

COMICS may be activated independently for configuring detector components

HV Record

Purpose Control and monitor an

individual HV channel Add high-level operations to a

basic voltage generator

Implemented as a sequential state machine with states, transitions, actions, and events

Ramping to a target voltage is a software function
