Cameras and Detectors

Opal
Camera (single panel) used for visible light detection in the timetool at a number of instruments.
Acqiris
Single or multi-channel DAQ boards for collecting and digitizing detector signals.
ADC
Analog-to-digital converter.
DAQ
Data acquisition system for online/real-time signal processing.
EPICS
Experimental Physics and Industrial Control System - Software suite aiding control of the DAQ and all associated hardware. Facilitates signal acquisition, feedback loops, reporting, logging, and instrument timing among other things. Certain EPICS variables provide entry points for control of individual hardware components, others for access to and manipulation of data/data streams.
PV
Process Variable. An EPICS variable.
