Computer Programs for AGS Injection

Since the injection system of the AGS requires very tight control over many parameters, computer programs were written to achieve this. One program initiates an emittance measurement device and reduces its output data to provide the characteristics of the linac beam. The second program utilizes these results to set six quadrupoles and four bending magnets so that requested beam parameters are obtained at the inflector exit. A third program measures the circulating beam and attempts to maximize it by adjustment of quadrupoles and bending magnets. These programs and our experience in using them on-line are described.
