== Friday 9th of March 2018 ==
=== Pre-data Taking Information and Notes ===
* The tests were carried out with an energy of '''36 MeV''' and '''28 MeV'''. A Bragg Peak measurement was carried out to confirm the exact beam energy.
* Collimators used: 20 mm diameter.
* PMMA sheets used: 3 mm, 2 mm and 1 mm, taped over the mylar window.
* 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'''.
** The '''DSLR ISO''' was always set to '''200'''.
** The light level in order to not saturate the sensor was reduced by placing green and blue see-through sheets in between the sensor and the scintillator stack for some of the tests.
* 8 x 32 mm scintillator sheets were used. The scintillator stack was set up in the following order, starting with the first sheet facing the beam:
** 7, 10, 13, 14, 15, 17, 18, 19
* '''Optical gel''' was '''not used''' for coupling, the sensor was placed directly on top of the scintillator stack.
* The dose received (as shown on the monitor in the control room) during the full day of measurements was:
** For the 36 MeV beam
*** With a 20 mm collimator: 435.5 uC
*** With a 20 mm collimator + PMMA sheets: 17.3 uC
*** With a 20 mm collimator + films inserted between scintillator stack and sensor: 536.2 uC
** For the 28 MeV beam
*** With a 20 mm collimator: 47.7 uC
* There current was variable/unstable throughout the day.
* To calculate the actual dose delivered to the scintillator:
** / 160 -> to convert to proton current
** / (50/ collimator diameter)^2 -> to account for reduction in area due to the collimator
* The directory containing the sensor data is:
'''/unix/pbt/data/birmingham/mar_2018/EPIX/XCAP/data/20180309_bham'''
* The directory containing the DSLR data is:
'''/unix/pbt/data/birmingham/mar_2018/Nikon/20180309_bham'''

Beam tests of the UCL plastic scintillator range calorimeter.

Thursday 8th of March 2018

Pre-data Taking Information and Notes

  • The tests were carried out with an energy of 36 MeV. A Bragg Peak measurement was carried out to confirm the exact beam energy.
  • Collimators used: 2 mm and 20 mm diameter.
  • PMMA sheets used: 3 mm, taped over the mylar window.
  • 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.
    • The DSLR ISO was always set to 200.
  • 6 x 3 mm scintillator sheets were used. The scintillator stack was set up in the following order, starting with the first sheet facing the beam:
    • 31, 32, 33, 34, 35, 48
  • The scintillator stack was coupled to the sensor using optical gel.
  • The setup can be seen in the following pictures:

scintillator_and_sensor.jpg IMG_3006.jpg

  • The centre of the "bare" scintillator (where the vice is not covering any of the scintillator face) was marked on the Mylar window and lined up with the beam using a film:

IMG_3009_rotated.jpg

  • The dose received (as shown on the monitor in the control room) during the full day of measurements was:
    • With a 2 mm collimator: 746.9 uC
    • With a 20 mm collimator: 417.7 uC
    • With a 2 mm collimator + 3 mm of PMMA: 251.5 uC
  • The current was variable/unstable throughout the day.
  • To calculate the actual dose delivered to the scintillator:
    • / 160 -> to convert to proton current
    • / (50/ collimator diameter)^2 -> to account for reduction in area due to the collimator
  • The directory containing the sensor data is:

/unix/pbt/data/birmingham/mar_2018/EPIX/XCAP/data/20180308_bham

  • The directory containing the DSLR data is:

/unix/pbt/data/birmingham/mar_2018/Nikon/20180308_bham

Pre-data Taking Information and Notes

  • The tests were carried out with an energy of 36 MeV and 28 MeV. A Bragg Peak measurement was carried out to confirm the exact beam energy.
  • Collimators used: 20 mm diameter.
  • PMMA sheets used: 3 mm, 2 mm and 1 mm, taped over the mylar window.
  • 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.
    • The DSLR ISO was always set to 200.
    • The light level in order to not saturate the sensor was reduced by placing green and blue see-through sheets in between the sensor and the scintillator stack for some of the tests.
  • 8 x 32 mm scintillator sheets were used. The scintillator stack was set up in the following order, starting with the first sheet facing the beam:
    • 7, 10, 13, 14, 15, 17, 18, 19
  • Optical gel was not used for coupling, the sensor was placed directly on top of the scintillator stack.
  • The dose received (as shown on the monitor in the control room) during the full day of measurements was:
    • For the 36 MeV beam
      • With a 20 mm collimator: 435.5 uC
      • With a 20 mm collimator + PMMA sheets: 17.3 uC
      • With a 20 mm collimator + films inserted between scintillator stack and sensor: 536.2 uC
    • For the 28 MeV beam
      • With a 20 mm collimator: 47.7 uC
  • There current was variable/unstable throughout the day.
  • To calculate the actual dose delivered to the scintillator:
    • / 160 -> to convert to proton current
    • / (50/ collimator diameter)^2 -> to account for reduction in area due to the collimator
  • The directory containing the sensor data is:

/unix/pbt/data/birmingham/mar_2018/EPIX/XCAP/data/20180309_bham

  • The directory containing the DSLR data is:
