First results of the Orsay beam size monitor for the final focus test beam

摘要

A gas-ionization beam size monitor has been developed for the Final Focus Test Beam (FFTB) at Stanford Linear Accelerator Center (SLAC), to measure dimensions in the nanometer range. This detector is also sensitive to longitudinal beam distorsions. The first extensive runs of the FFTB have been performed in April 1994. We report here the first results of the monitor.
