Calibration Device for Scintillators

Overview

Create a linear motion device that will calibrate a set array of Scintillators using light pulses

We need to find something that is low cost but is accurate enough to be stopped at each fiber array block. This would call for a low pitch. One example I've found is as low as 8mm pitch with 200 teeth making a 1.6 meter timing belt. Because the intended light source for calibration is most likely going to have a wide range, 8mm is a fair sized step as the scintillators are 2mm each but grouped in blocks.
