چکیده
Many people are experienced in measuring radiation dose from photons and electrons. These two forms of radiation involve similar measurements since it is secondary electrons produced by the photons which actuallv deliver the dose. The electron is a light charged particle. Relatively fewer people have experience in measuring neutron dose. The neutron is a heavy uncharged particle. It has nearly the same mass as a proton, i.e. the nucleus of a hydrogen atom. Most of the neutron dose is actually deposited by secondary knock-on protons, but significant fractions come from other heavy particles,secondary electrons and y-rays.

Cid Thermionic Gun System*
A new high-current thermionic gun has been installed on the CID injector at SLAC and brought into operation. The gun and pulser system generate three nanosecond pulses of about six amps peak which, when bunched in the subharmonic buncher system, produce in excess of 1011 electrons in a single S-band accelerated bunch. Preliminary operation of the gun is described, and details of the avalanche c...

A proposal for the form of the ground state wave function of quantum chromodynamics is made. It is shown to lead to the phenomenology of the MIT Bag Model. The parameters of this model are related to the fundamental scale parameter of QCD.
متن کاملSLAC B Factory Computing
As part of the research and development program in preparation for a possible B Factory at SLAC, a group has been studying various aspects of HEP computing. In particular, the group is investigating the use of UNIX for all computing, from data acquisition, through analysis, and word processing. A summary of some of the results of this study will be given, along with some personal opinions on th...
