Experiment List

ISDI Sensor Instructions General Sensor Configuration Base Configuration is 14 x 1 Bit Resolution is 1030 x 1536 pixels For selecting pixel rows in centre: Use horizontal offset (ignore DVAL to activate field) and horizontal resolution

Increase number of frame buffers To increase the number of frame buffers to the allowed maximum, start XCAP as administrator. Select Capture/Sequence Capture/Video to Frame Buffers/Driver Assistant Tick box in left field, then set number of frame buffers here.

Serial Terminal instructions for ISDI sensor Find serial terminal in PIXCI(R) tab of sensor control software. In Controls/Options: Make sure "Send string with CR" is selected. Should be default. In Controls/Setup: Select Serial Port: Enabled. Baud rate has to be 115200 Set low full well mode using W000300000 Set high full well mode using W000300004 Read full well mode using R0003

Continuous Field buffer setting This setting makes sure that the buffer is filled with a new frame as they come in. If this option is not selected the sensor and software will not be synchronised and we will record a lot of pitch black images. Select Capture/Live Options//Live Mode/Live Video: Continuous All buffer capture

Range calorimeter measurements with ISDI sensor + scintillator stack.

0. Find convenient beam intensity that does not saturate sensor: lowest clinical beam energy, smallest beam focus 1. Calibration of detector (highest clinical energy). Shoot from front and back of stack (we have a new entrance window at the back of the stack). Also calibrate at different focus sizes. Also test camera: focus on front of beam stack and centre of beam stack and compare. 2. Test focus (beam size) dependence: shoot pencil beam with ~10 cm range at different focus sizes 3. Measure WET of known blocks of plastic to calibrate range telescope using a pencil beam with ~10cm range. Lennart will check if he can find some PMMA slabs whose WET has been accurately measured. Ideally have some slabs between ~1mm and ~5cm WET thickness. We know that there are some PMMA slabs between 1mm and 5cm thickness, measured by Giulia Arico (OMA fellow). These measurements will be used to benchmark Laurent's reconstruction code. Use tightest beam focus. 4. Repeat 0.-3. with all available ions (protons, helium, carbon and oxgen) 5. Measure SOBP of protons. 10cm deep, 3cm plateau 6. Measure high proton energies (up to 250MeV) using PMMA absorber in front of range telescope. 7. Measure a couple of oxygen pencil beams (range shift) and SOBP 8. Disassemble detector.
