9 INCH CYCLOTRON DAQ AND CONTROLS

Although considered obsolete in this day, the HP85 proved to be an extremely versatile piece of test equipment. Itís ability to control any HPIB ready unit has made possible a flexible data control and acquisition system. The simple HP Basic language allowed even the most novice programmer to exercise complete equipment control. Although the processor is slow, speed was not an issue as the magnetic field needed to be ramped even slower. Future needs that may arise from active feedback certainly would require a faster computer. A minimum of data manipulation was completed by the HP85, all data that was collected was immediately transferred to a PC via an RS232 link. The PC terminal program wrote all data to disk leaving analysis to be completed off-line.
