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
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
