Beamline Control
The beamline is run by Sun workstations (UNIX/Solaris) and VME-based electronics. The VME-based equipment is controlled by EPICS. There are several software clients that use EPICS, including MEDM, Python, and SPEC. Other computers, such as PCs, are used to run specialized pieces of equipment (e.g., the CCD camera).
