EPICS Process Variables for SPEAR 3 Accelerator Physics Applications
J. Corbett
June 12, 2003
SPEAR 3 accelerator programs written in MATLAB rely on Channel Access to communicate with the
main control system. This note contains a list of primary signals accessed by these programs. PV names are
not specified.

QUESTION: is there some way to specify how many orbits the user wants to retrieve from the ring
buffers?
