*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.

*To operate the linear motion stage, a series of electronics is set up that works together to move the pulley system. First a computer program built with Labview was created to communicate with the Digital to Analog Controller(DAC) via USB. The DAC has pin-outs arranged similarly to a serial port, that control the driver. The R208 microstep driver has various wires connected to the DAC.  When the circuits are opened and closed via the Labview program, the stepper motor steps forward or backward. From the driver, the 5V logic power wire is connected to the 5V output on the DAC and the 24V, 2 Amp power driver wire is connected to the power supply. The logic ground and power ground are also connected to the power supply ground. The stepper motor in use is a 1.8 degree high-torque model with a four wire connection.[[File:Electronic Setup.JPG|thumb|Electronics]]

*The user can select a left or right direction, how many steps per interval, the number of iterations and the time delay between iterations. The program tracks the current location of the rail carriage based on the number of degrees rotated.
