Computer Control of the M.S.U. 50 MeV Cyclotron

The MSU cyclotron control system employs a novel concept of operator-machine interface. An Intel 8080 front end microprocessor to a DEC PDP 11/20 minicomputer is dedicated to the control of the trim coils and centering coils and the beamline quadrupole magnets. The operator has control of these elements through dedicated control modules. Each module has a digital readout, a thumbwheel switch and a rotary knob for control of the setpoint. Standard CAMAC hardware is used in the interface. The R.F. system tuning elements can also be set with the computer. Radial beam current traces can be taken and displayed on a graphics terminal. A link to the laboratory ¿-7 computer allows access to its mass storage devices and peripherals.
