Controls for Operating and Processing, Tihe MIT-LNS LINAC

The Central Control Room for the MIT Linac is designed for simplicity of operation (one man) with an eye on future use of a computer to set the desired operating parameters. A natural summing of local controls around the five RF driver/dual-modulators and the injector/master oscillator control room allows one to switch to the display and control of the six areas one at a time with a trunk line. The distributed parameters (magnetics, radiation and RF phase monitoring) are mostly monitored and controlled directly from CCR with pushbutton selection of each parameter. Also mentioned are the detailed results of RF processing the 7m, S-band accelerator sections with 15ps, 4MW pulses at repetition rates exceeding 1000 s-1 and phase tuning the rectangular waveguide networks using a combination of the SLAC method and beam loading maximization.
