As we have the scanning setup ready to make measurements in different points of the PMT, our idea is to flash the LED is a small light intensity in various point to measure the gain in function of the position.

After that, we can analyse each position individualy as a first approach. But we want to write a root script to analyse all of the positions automatically. This way it will be possible to make scans with higher resolution.

Scanning setup

The design and the picture of the scanning setup and can be seen in the following figures.
