Wish List for PFE Features

[John Donovan]

Is it possible to include the beam 2 values in the Analyze window? Right now, you can only see them in the working window. See attached files for reference.

Almost everything is possible. But some things are more work than others!. 

Let us take a look at this.

Is it possible to change the frequency of beam current measurements during an analysis run? I poked around, and all I found was “on/off” in the Acquisition Options dialogue, and didn’t see anything relevant in the Probewin.ini file.

I currently have an incredibly stable gun, with typical drift of 0.05% per hour, and as you know, due to the Faraday delays on JEOL probes, the current measurement protocol actually eats up 5-10 seconds per analysis. Would be super cool if I could set it to read the current every X number of analyses, or every X number of minutes.

I can see how that might be tricky to code into the current normalization calculations in Analyze!, but thought I’d mention it and see what you thought.

We modified the code to add a new checkbox in the Acquisition Options (v. 13.2.9) that now allows the user to only acquire the beam (and absorbed) current once per sample as shown here:


 
When this option is selected then the program only acquires a single beam (and absorbed) beam current measurement per standard or unknown sample and just re-load that first measurement for subsequent data points in that sample, as seen here:

Off-Peak Corrected or MAN On-Peak X-ray Counts (cps/1nA) (and Faraday/Absorbed Currents):

I like the Sort Stat and Data Grids by Geologic/Atomic Number in the Analyze window (see attached screenshot). Is there a way to turn that on all the time?

The only way you can have it "on all the time" is to simply enter (or change the order of) the elements in a sample. For example either when entering the analyzed elements manually from the Elements/Cations dialog or using the up/down arrows in the Combined Conditions dialog from the Acquire! window.

However, you can specify the default sort order by editing the Probewin.ini file as seen here:

[software]
GeologicalSortOrder=1      ; 0 = no sorting, 1 = traditional, 2 = low to high Z, 3 = high to low Z

Hi John,

I know there's been a lot of work in all the new deadtime corrections, and they look great, but would it be possible to decrease the available deadtimes to below 0.1us? I've tried changing the deadtime in both PfE and directly via the scalars.dat file, but I come up against an error both ways so I'm guessing there's a sanity check in the software.

0.0001us or something would be great 

Thanks

"Sanity check" is a good way to describe the 0.1 us minimum dead time allowed in the SCALERS.DAT file...   

Seriously, why would you need this?  No WDS hardware I know of can go that low!  If you only want to turn off the dead time correction, just turn it off in the Analytical | Analysis Options dialog!

But actually there is a way... just use the Analytical | Update Dead Time Constants menu dialog to edit the values to any value between zero and 20 us.  It only updates values for the samples you select in the current run, but it's good enough for "what if" types of questions. You will get a warning to the log window if the value is zero though.

I'm just curious why you'd want to do this.... if you just want to try some modeling just use the TestEDS application and use the Output | Output Dead Time Calculations menu as described here:

Works like a charm, thanks!

The SXES can!

Really!?   I didn't know that.  Too bad JEOL can't utilize the same pulse processing electronics for our WDS spectrometers!

I'm assuming that PFE is not reading a SXES spectrometer? Correct? But you are somehow able to read the SXES spectrometer in PFE I will edit the "sanity check" for reading the values in the SCALERS.DAT file.  How low can the dead time values get on the SXES?
