Contents Introduction
The AGS Booster has operated since 1991 as a pre-injector of protons and heavy ions into the AGS. Over the past decade the operation of the Booster has evolved such that it now always operates in the linear regions of the magnetic elements. Most recently, though, the Booster was modified to allow for slow extraction of ions to the NASA Space Radiation Laboratory (NSRL). This facility is designed to employ heavy ion beams of many different ion species and at beam energies ranging from 0.04 to 3.07 Ge V/nucleon. Many of the modes of operation required by NSRL will be operating the Booster at the limits of the magnets and respective power supplies. In order to allow operating at the highest fields it was necessary to upgrade the tune quadrupole trim power supplies, to provide a larger area of tune space maneuverability. To allow us to experimentally explore these high rigidity regions of the Booster lattice we needed a flexible yet powerful beam diagnostics system, which would provide the highest possible fidelity of information from Beam Position Monitors (BPM) and the Booster wall current monitor. In this report we will describe this system and show examples of its use.
