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

DDC232 Instructions

  • Bash script prog.sh executes FTDI.cpp and livePlot.cpp. Execute with . prog.sh 2 350 170 0 50 true Data/capture.txt in the directory Photodiodes.
    • First argument is the number of DDC232s.
    • Second argument is the full-scale range (FSR) in pC. Choices are: 12.5, 50, 100, 150, 200, 250, 300, 350.
    • Third argument is the integration time in us. Range is 170-1455. Set in multiples of 5 us.
    • Fourth argument is the number of measurements to acquire. Typically acquire 5700 measurements per second. Set to 0 for infinite loop.
    • Fifth argument is the rate in Hz to update the file average.csv for ROOT/web GUI plotting.
    • Sixth argument is a boolean to choose whether to display the ROOT plot.
    • Seventh argument is the filename and destination for the output hexadecimal data.
  • After acquisition, close ROOT by choosing File->Quit in the ROOT window and then stopping DAQ (if in infinite loop) with CTRL-C.

Experiment Plan

  • Shoot-through measurements (back & front) for light calibration and level setting.
  • Range measurements between 70-120 MeV with 1mm steps with CMOS sensor and photodiodes.
  • High intensity range measurements between 70-120 MeV with 1mm steps with photodiodes at optimal light level.
  • Live measurement of 3cm x 3cm x 3cm treatment plan.

Experiment Notes

Range calorimeter measurements with ISDI sensor + photodiodes.
