Abstract

Experiments have been conducted to evaluate the feasibility of conducting pointing stability measurements with a relatively low cost stand alone apparatus. These experiments also aimed at collecting beam wandering data for pointing stability measurement system engineering purposes. The system consists of two dual-axes position sensing detectors (PSDs) that simultaneously measure variations of the beam position in two different planes. Sample-and-hold circuits are used to synchronize measurements taken by both PSDs. Detector signals are amplified and processed analogically in order to obtain voltage outputs directly related to beam position. The output signals are then A/D converted for computations. Software allows pointing stability calculations as well as frequency spectrum analysis of position fluctuations.
