Beam tests of the UCL single module at medAustron.

The tests were carried out with an energy of 252.7 MeV with a 5 second beam spill and a range of intensities.
No collimators were used at any point.
The setup consisted of:
- 2" Hamamatsu R13089-100-11 PMT with negative HV active divider base (made by Hamamatsu)
- coupled with Eljen optical gel to a
- 3 cm x 3 cm x 45 cm cuboid ENVINET standard scintillator wrapped in two layers 6 um (each) of Mylar
The "pensioner" 5 dynode stage PMT was also briefly tested, but no sensible data was able to be acquired.
The digitiser always operated in Self Trigger mode.
Working directory where digitiser data is stored:

C:\Users\abf\Desktop\digitiser_data\medAustron\mar18\ham
