Overview

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

Ideas

  • Printer disassembly and take-over of printer head linear motion through use of serial port programming with C
  • Worm gear connected to DC motor with micro controller set up
  • Linear Rail system
  • Stepper Motor Belt System

Belt System

  • Stepper motor with micro controller stands stationary on one end and calibration device would be connected to a slide rail system for stability
  • 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.

McMaster-Carr Timing Belts and Pulleys

Motor

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