Abstract :
The detection equipment installed in the Zero Gradient Synchrotron (ZGS) is described. Most measurement techniques and equipment are similar to those of other synchrotrons with the possible exception of fluorescent screens of high transmission viewed by storage TV systems. We find these useful for a variety of diagnostic techniques at injection, such as measurement of equilibrium orbits, median plane, injection angles, and angular spreads. The value of these techniques, which depend upon the focussing properties of the synchrotron, lies in their ability to separate magnet effects from injection effects. These techniques are described in some detail. Also discussed briefly are some of the problems that we have encountered, such as unbalanced ground currents, tune variation during the accelerating cycle, and a vertical instability with a sharp intensity threshold.
