A custom run plan was created to test simulated results. This run plan began with an attempt to show reproducibility. To find how reproducible the OSLs are, a single OSL was placed in the center of the beam spot of the 25b accelerator at the IAC. The IAC engineers set up the centered laser for experimental use, and using a glass plate placed at 50cm, OSLs were exposed to a differing number of pulses under the same beam characteristics. The characteristics chosen for this experiment for are a beam energy of 8MeV, pulse width of 500ns, and peak current of 50mA.

-> Run plan

In doing so, dose per pulse measurements are recorded. It was determined that it was best to keep. the OSLs in the middle of the operating range, which has a maximum listed at 1500 Rad. Due to the energy of the beam and the optics used therein, six pulses was the maximum that the OSL could handle while staying in the middle of the range.

The point of the electrons was to find dose/pulse information on-axis of the accelerator to help find total dose for quartz. This information was then used to irradiate some quartz and ABS plastic samples to a known dose, to allow for rad hard tests. Along with structural integrity tests in the plastic. (transparency in quartz).
-> pulse number vs dose graph (maybe extrapolate to higher number?)
