Frequently asked questions

Which detector is used?

MiniPIX-D08-W0313, with a Timepix chip, a 500 µm silicon sensor, and readout serial number 2746. Do not substitute specifications for Timepix3 or a 300 µm sensor.

Why is `FileDevice 0` reported?

It is a PIXet file device; the controller rejects it as a physical detector. Check USB, drivers, and device detection in PIXet.

Does `set_threshold()` accept raw THL?

No. It accepts keV. Do not pass the certificate’s THL=691 as the argument.

Why does Integral return one image?

It uses PIXet’s integral acquisition and retains the final image, rather than summing all frames in Python.

Are ToT values expressed in keV?

Not necessarily. Verify the energy calibration and PIXet’s data representation.

Is 55 fps guaranteed?

No. It is a product maximum; dead time, storage, and SDK processing affect practical throughput.
