*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.

*Need to locate a stepper motor to attach to one end of the pulley belt system

*LinEngineering 1.8 Degree Motor 'WO-4118S-01' was found to be appropriate and cost effective. [http://www.linengineeringstore.com/products/product_detail.aspx?proID=2]

 

*With a LinEngineering 1.8 Degree Motor and a radius of .5" for the pulley, the step size would be 0.005" or 0.127mm which is well within a 2mm scintillator.
