Proton Calorimetry/Experimental Runs/2018/Mar22: Difference between revisions

Revision as of 02:17, 21 September 2018

Beam tests of the UCL plastic scintillator range calorimeter.

Data was acquired with the DSLR camera and the ISDI CMOS sensor.
The average background value per pixel for the sensor is ~ 2500. The sensor pixel dimensions are 1030 x 1536. The sensor frame rate was always set to 25 frames per second.
NO optical grease between scintillator and sensor.
Beam is extracted over 5 seconds (one spill). The full capacity (100%) of the synchrotron ring is 1.2x1e10 protons.
Scintillator stack arrangement: 15 x 2 mm, 15 x 2.6 mm and 1 x 3 mm sheets used: In ascending order from the back of the scintillator to the front/beam. Except for sheet number 21 (2mm) which is placed at the end (away end from the beam) of the stack because of a crack in the sheet. Sheet numbers from front to end (in beam direction): 31,25,24,23,20,16,12,11,9,8,6,5,4,3,2,1,30,29,28,27,26,22,19,18,17,15,14,13,10,7,21
Folder for DSLR images: digiCamControl/20180322_medaustron
Note: When powering on PC, sensor has to be connected, but unpowered!
16383 = saturation pixel number (16 bit x 1 tap)
Sensor images are always saved as a sequence of 21 Tiff images
