[Requirement] Timepix image intensifier saturation workflow. #24

Open YooSunYoung opened 3 weeks ago

YooSunYoung commented 3 weeks ago

Executive summary

Scan different gains of the image intensifier and find a saturating point.

Context and background knowledge

After setting up a timepix detector, we need to optimize the gain of the image intensifier.

Inputs

Collected timepix image and image intensifier gain (timestamp needed)

Methodology

As increasing/decreasing gain, the detector should have inconsistent increasing/decreasing of intensities along the (?)... We compare n+1th image with nth image and find where this effect disappears(saturates).

$$intensities(gain{n+1}) / intensities(gain{n})$$

Should be a flat line.

Outputs

Which interfaces are required?

Python module / function, Jupyter notebook

Test cases

TODO: We need a timepix image intensifier optimization test file.
