A monochromator is important to a beamline for desired monochromatic light. There are three water-cooled
double crystal monochromators (DCMs) commissioned in the phase-I beamlines of Shanghai Synchrotron Radiation
Facility (SSRF). In this paper, the mechanical principle of the DCMs is introduced. A control system for
the monochromator based on the standard architecture for SSRF beamlines is described. To achieve the control
requirement precisely, the hardware includes VME (Versa Module Eurocard)-based controller for stepper motors,
RS-232-based controllers for micropositioning and piezoelectric actuators. The software is developed with
EPICS (Experimental Physics and Industrial Control System) package. Test results have revealed the stability
and reliability of the system.
