Application of Local Area Networks to Accelerator Control Systems at the Stanford Linear Accelerator

LIONs at the Stanford Linear Accelerator Center

The term LION is an acronym for Long Ionization Chamber. This is a distributed ion chamber which is used to monitor secondary ionization along the shield walls of a beam line resulting from incorrectly steered charged particle beams in lieu of the use of many discrete ion chambers. A cone of ionizing radiation emanating from a point source as a result of incorrect steering intercepts a portion ...

Vibration Studies of the Stanford Linear Accelerator†

Vibration measurements of the linear accelerator structures in the SLC linac show a 1 micron rms vertical motion. This motion reduces to 0.2 micron rms motion when the cooling water to the accelerator structures is turned off. The quadrupoles have 250 nanometer rms vertical motion with the accelerator structure cooling water on and 60 nanometer motion with it off. These results together with me...

Microwave Studies at the Stanford Linear Accelerator Center* 3 I

The fundamental role of microwave power at SLAC is to accelerate the electron beam along its two-mile course. The traveling wave acceleration of electrons in conventional machines has been extensively treated in the literature, however, and will not be discussed here. Nevertheless, there are some microwave problems and developments of recent origin, two of which will be described in this paper....

Tunnel Radio Commljnications System at Stanford Linear Accelerator Center *

A unique single frequency, dual daisy chain tunnel radio communication system has been developed for use in our new Positron-Electron Storage Ring. Communications are possible between portables in the underground ring and between a portable in the ring and all control rooms on the site. The system is designed as a wide band facility and therefore can carry many simplex and duplex transmissions....
