Optical telemetry control and data transfer system

PDF Version Also Available for Download.

Description

A multichannel telemetry system has been designed and constructed to control and monitor duoPIGatron ion sources. With the exception of the accelerating and decelerating power supplies, all other power supplies and H/sub 2/ gas control that operate the ion source are elevated to accelerating potential. The telemetry system operates and monitors the isolated power supplies and transmits data across the high voltage gap. The transmission medium is infrared light pulsed through 10 ft-long, /sup 1///sub 8/ in-diam fiber optics, one end at high potential and the other end at ground potential. Conversion is accomplished by digitizing analog signals before transmitting ... continued below

Description

A multichannel telemetry system has been designed and constructed to control and monitor duoPIGatron ion sources. With the exception of the accelerating and decelerating power supplies, all other power supplies and H/sub 2/ gas control that operate the ion source are elevated to accelerating potential. The telemetry system operates and monitors the isolated power supplies and transmits data across the high voltage gap. The transmission medium is infrared light pulsed through 10 ft-long, /sup 1///sub 8/ in-diam fiber optics, one end at high potential and the other end at ground potential. Conversion is accomplished by digitizing analog signals before transmitting through the optical system and demodulating at the terminating end. A maximum conversion rate of 100 kHz provides adequate resolution to operate the ion source. The output data is documented and stored in a PDP-11 computer. Although the control input is computer compatible, no attempt has been made for closed loop feedback control of the ion source.
