X-Ray Generator¶

Comet¶

Comet provides a wide range of indutrial X-ray generators.

Usage¶

Note

The generator needs to be turned to Remote control (Mode 400): Change the mode on the X-ray generator controller: Press CTRL+4, the “mode” on the top left of the controller screen changes from 000 to 400.

Turn the key back to the ~ sign, then to the lightning bolt sign. Press 1 to launch the X-rays, the system is now awaiting commands from BLISS / SPEC. Repeat this sequence each time you performed a new search.

Function	Documentation
`comet.status`	Check status
`comet.current_setpoint = XX` in mA / `comet.voltage_setpoint = XX` in kV	Set voltage / current setpoint
`comet.current` / `comet.voltage`	Check current values of voltage, current
`comet.focus = Focus.standard` / `comet.focus = Focus.small`	Set focal point size where Standard is 5.5 mm2 and Small 1 mm2
`comet.focus`	Check the current status of focal spot size
`comet.hvoff_time_disable()`	Unset exposure time
`comet.hvoff_time=xx [s]`	Set exposure time (minimum 2 s)
`comet.hv = True \| False`	Switch beam ON / OFF
