OSL Data Analysis

Using the OSL reader, PMT counts for each OSL are recorded. Using these counts and the high dose calibration created with the Cs-137 source, the dose can be calculated. Following the reading of the OSLs, the raw data and errors is input into a text file and fed into a data analysis script. The script takes the raw text file and interprets it into multiple different images. As the OSLs are discrete, a square array is created with X (beam right) and Y (beam up) coordinates, along with the dose intensity on the Z axis.

-> array of discrete images -> put a note in the image about the beam being incident in the -Z direction

It is possible to use ROOT to interpolate the discrete array of OSLs to a more continuous surface. With this interpolation, it is also possible to fit a two dimensional gaussian to the image to garner a thought at what the incident beam may look like.


-> Gaussian formula used in code

-> interpolated image with gaussian (electron array 3 or photons average maybe, use the images from the same set as above) -> put a note in the image about the beam being incident in the -Z direction
