New Features In Probe for EPMA

Log plot works nice too:

This is a small but useful (I think) feature:

Basically, you can now set the number of points to skip when displaying TDI trend curves. For example, in this TDI plot, with all the data displayed (Nth = 1), the plot is rather dense:

But if I set the value to 3, it plots the TDI trend only every 3rd point:

Not such a big deal, but later when I implement a TDI correction for x-ray maps, this will be very helpful when plotting TDI trend curves for thousands of pixels!

All,
I am very pleased to announce that Probe for EPMA can now acquire CL spectra for point analyses automatically (along with your WDS intensities and EDS spectrum data). Right now we are only interfacing to an Ocean Optics spectrometer (I'm using the USB4000 unit right now), but other vendors could be supported also.

Here is an example of a CL spectrum and the corresponding dark spectrum:

I picked the Ocean Optics spectrometer hardware to start with because it's not too expensive and if you already have the CSIRO xCLent system on your EPMA instrument, the Ocean Optics spectrometer is already there, connected to the computer and already interfaced.

If you are interested in this option, please contact Barbara (@probesoftware.com) and she will send you a quotation for the CL acquisition software interface.

I do not believe that even the JEOL software can automatically close the V1 valve using their own Serial Acquisition software! I think this is only done manually using the 'OFF' button in the PC-SEM software.

Hi Dan,
That is interesting, but in any case, I've asked JEOL Japan to provide an API call for controlling this valve for over a year now.

But feel free to bother your local JEOL people about this. They respond better to their customers than to me.

New wavescan graphics in the Probe for EPMA Plot! window:

Please let me know what you think...

It may be a small thing but I think it helps new users:

The latest version of PFE (v. 11.2.5) can display KLM markers and absorption edges in the MultiPoint Background dialog for multi-point bgds and "shared" bgds:

I can't remember who asked for this, but it's a great idea! Thanks.

Here are some screen shots (attached below) showing the new KLM markers for spectro, angstrom and keV plots.

It all seems to work really nice now.

Improved KLM marker plotting in KeV space for user specified elements:

Hi John
The new graphics look great - much smoother. Only suggestion I have is to keep the font consistent. The times new romanoid headings look strange against the arial of the the axes. Looking at it makes my teeth itch........

Cheers
