SP3 at the minute, I hadn't thought of trying to add SP5 to our instrument. I might have a think about that!
Our SXES-LR on the 8530F takes up the SP5 position, hence our instrument only having 4 "traditional" WDS.

I was just thinking then you could just have a fifth spectrometer used only for this SXES purpose... but to make it work I think you'd have to set the DisableSpectrometerNumber keyword to 5 in the Probewin.ini so the program essentially ignores it for automation as shown here:

[hardware]
DisableSpectrometerNumber=5      ; disable spectrometer flag allows a single spectrometer to be ignored by the program

And of course you'd have to enter dummy values for a 5th spectrometer in the SCALERS.DAT and MOTORS.DAT configuration files.

For the Analytical | Update Dead Time Constants - is there an equivalent way of doing this for CalcImage?
At the minute I'm doing exactly as you suggest - dividing the measured intensities across the board by an order of magnitude or two, which wouldn't make a difference in the grand scheme of things, but it would be nice if I didn't have to!

The updated dead time constants from the PFE dialog will be applied to the CalcImage maps automatically as long as you update the dead time constants in the sample used for the "Sample Setup" in CalcImage, from Probe for EPMA using the Analytical | Update Dead Time Constants menu.  I will try to modify the "sanity check" in the SCALERS.DAT file...

I'll see what I can do about creating some demo data for quant mapping with the combined WDS and SXES: the work I've been doing has all been on client data. I work quite a lot with light elements, and the SXES is a game changer for this.

No rush, but that's very interesting to hear.   It's too bad JEOL doesn't provide us with a way to read that spectrometer directly in Probe for EPMA.  You should bug them about this.  I know that Anette and Mia Kraft were working on this before Anette left for UBC.

Yeah, I've got the SXES data going in to PfE and CalcImage.

It'd be great if I could put a dead time value as low as 0.0001us or something ridiculously small in to scalers.dat. My worry is that the very large CPS/nA values I get from integrating the SXES peaks is getting inappropriately dead time corrected.

We have modified the SCALERS.DAT "sanity check" to allow dead time values as low as 0.0001 us.

Update using the Probe for EPMA Help | Update Probe for EPMA menu as usual.

Thanks very much!
