Experiment Plan

1st Day: Tuesday 30th of April

2nd Day: Wednesday 1st of May

1) Shoot-through of old scintillator stack at 250MeV to check prior calibration. 50mm absorber -> scint stack -> pixel sensor -> TC -> water dump. Both directions for stack so will rotate midway through.

2) Shoot-through calibration of new scintillator stack 1 at 250MeV. 50mm absorber -> scint stack -> pixel sensor -> TC -> water dump. Both directions for stack so will rotate midway through.

3) Shoot-through calibration of new scintillator stack 1 at 250MeV. 50mm absorber -> scint stack 2 -> scint stack 1 -> pixel sensor -> TC -> water dump. Both directions for stack so will rotate midway through. Full QuARC cabling complete here.

3a) Background measurement of scintillator stacks 1+2

-- UCL: Add calibration files to appropiate file for GUI

4) Rotate gantry to front of case. Full system check at 160MeV with beam on axis. Check readout of TC and pixel sensor.

5) Range tests with on-axis beam at 70, 90, 110, 130, 150 and 170 MeV. Beam on axis.

6) TC calibration with 1 second beams at 110 MeV and 160 MeV.

7) Position tests for pixel sensor with manual adjustments in couch position. Check QuARC readout for nonlinearities.

8) Treatment plan single position range scan (if available from UCLH).

9) Treatment plan box field scan for 3 x 3 x 3cm and 5 x 5 x 5cm volumes (if available from UCLH).

10) Brain tumour scan (if available from UCLH).

If none of the treatment plans are available we may have to go through and do some of the position/energy steps manually.

Experiment Notes

Original data will be saved in pi5: /home/pi/GUI/v3.01b/UCLH/

A copy ot the hexadecimal files will be saved to: /unix/pbt/data/uclh

For each run three files will be generated:

• Run0xy.txt: raw hexadecimal data

• RunOxy_calibrated.txt: calibrated data with background subtraction. An average measurement is at the bottom with a run performed to it. Visualisation with acquisition on DAQ.html

• Run0xy_fitted_25Hz.txt: data averaged at 25Hz and fitted, with range and energy values extracted. This can be visualised in the REPLAY.html tab of the GUI.

Day 1 Technical Notes:

1. 1 Photodiode in stack #3 broken (either the first or the end one) prior to the beam test.
2. Position of the couch: -11.80cm, +82.20cm, 0.00cm, 0˚, 0˚, 0˚
3. Position of the Gantry: +90˚, +42.10cm
4. Stack connected using USB-C (long cable (1m Wuerth Elektronik) in the peli case, and short cable (15cm Multicomp Pro Short) is outside the peli case)
5. FPGA and FMC Daughter board is located outside the peli case.
6. Calibrated and fitted data of stack #3 is using photodiode position of stack #1, so it needs to be corrected in post processing.

Day 2 Technical Notes:

1. The couch position is slightly shifted to maintain consistency due to the positioning of the QA equipments is one section ahead (-11.80cm, +96.45cm, 0.00cm, 0˚, 0˚, 0˚)
2. Find out the crazy noise in the first day DaQ is due to the delay switch setting in the FPGA set to 0 instead of 2.
3. Spare raspberry pi had the wrong date set up when acquiring data, so the metadata of files Run063 to Run085 will show that they were acquired on the 29th of April instead of 1ts May. They have been manually placed in the correct file 20240501.
