auto gain

[Cathyhjj]

I remembered you had a feature to let ion-chambers adjust their gain automatically during a scan? How to use that feature?

[Cathyhjj]

Or maybe another way: can the ion chamber gain value changed in the queue? Could it be used in the move_motor plan?

How to use that feature?

Just run the auto_gain plan. For example:

RE(haven.plans.auto_gain([I0, It, ...]))

It can also be run in Firefly through the voltmeters window. Select which ion chambers to include with the checkboxes labeled "Auto-gain", and click the "auto-gain button at the bottom to add it to the queue:

Or maybe another way: can the ion chamber gain value changed in the queue? Could it be used in the move_motor plan?

Yes, that would also work. The preamp is a child of the ion chamber, so you should be able to find it in the selector (and don't forget the offset).

adjust their gain automatically during a scan?

To be clear, there's not support to adjust the gain during a scan. Is this something we want?

[Cathyhjj]

I don't think we want to change the gain during a scan, changing in queue is great! Thanks!

[Cathyhjj]

Sure!
