Tunnel Radio Commljnications System at Stanford Linear Accelerator Center *
نویسنده
چکیده
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. This system utilizes TV twinlead as a distributed antenna and repeater amplifiers to cover more than 7000 feet of underground tunnel. The design philosophy, tests and initial design will be discussed and contrasted with the final implementation of the system. Future uses of the system will be discussed.

The Slac Pulsed X-ray Facility*
The Stanford Linear Accelerator Center (SLAC) operates a high energy (up to 33 GeV) linear accelerator delivering pulses up to a few microseconds wide. The pulsed nature of the electron beam creates problems in the detection and measurement of radiation both from the accelerator beam and the klystrons that provide the RF power for the accelerator. Hence, a pulsed x-ray facility has been built a...

The Final Focus Test Beam (FFTB) is a new beam line at the Stanford Linear Accelerator Center designed to test new beam optics concepts, hardware, and techniques necessary to achieve and measure the small spot sizes required for future generations of high-energy e+e- linear colliders. The FFTB takes a 47 GeVc-1, 1 kW electron beam at the end of the Stanford Linear Accelerator Center linear acce...

Our primary role in the genesis of PEP-II, the energy-asymmetric B-meson factory at the Stanford Linear Accelerator Center, has since evolved into a major collaborative construction project. The project, when completed, will greatly facilitate the study of CP violation. Our scientists and engineers remain involved with PEP-II, especially in beam dynamics studies and in rf and feedback systems. ...

These days the linac at the Stanford Linear Accelerator Center (SLAC) is mainly an injector for the PEP-II rings. But besides the electrons and positrons for PEP-II, it provides a 30 GeV electron or positron beam to the end of the linac into the FFTB (Final Focus Test Beam) area or creates a test beam for the A-Line. In the FFTB tunnel there are two plasma experiments installed, which have demo...
