RE: xspress3

[<nick.rees@diamond.ac.uk>]

Hi Matt,

We are doing some work at Diamond - starting by simplifying the driver so that it has far fewer parameters in the NDArray, and making it simpler to scale the system by number of channels. This should make it more performant and able to scale to higher speeds and/or more channels.

I would be interested if anyone actually uses the ROI's that are stored in the data file. These add a lot of attributes and have a lot of overhead - both manipulating the NDArray every frame, and also when writing the file at the end - because it writes all the parameters after the scan finishes.

Cheers

I am looking for a quick survey of people with a xspress3 from Quantum Detectors.

Do you you have any feedback on the driver?

Have you made any changes to the EPICS driver that aren't GiHub? If so, are you willing to put it up on GitHub?

Thanks,
Matt
