A simple interlocked controller for research vacuum systems
We describe a simple, low-cost circuit that we use to control and supervise the operation of a radio-frequency plasma chamber. The unit has been designed for flexibility and ease of construction, all control logic being programmed into read-only memories. Feedback allows the unit to operate as a state machine, offering a limited degree of control complexity without the need for more than a simple EPROM programmer.

Abstract

We describe a simple, low-cost circuit that we use to control and supervise the operation of a radio-frequency plasma chamber. The unit has been designed for flexibility and ease of construction, all control logic being programmed into read-only memories. Feedback allows the unit to operate as a state machine, offering a limited degree of control complexity without the need for more than a simple EPROM programmer.
