Wish List for PFE Features

[John Donovan]

We can confirm this numerically but running the quantification. Here is the TDI without aggregation:



Note the DEV% number. Now, here with intensity aggregation:



Notice that the TDI DEV% went from 0.6% to 0.2%, a decrease of a factor of three. TDII: is the intensity intercept and TDIL: is the log intensity intercept.

Hi John
Super cool. Many thanks for developing and implementing that over such a short span, I think it will be very useful. I have sort of highjacked the Wishlist thread into a development thread, so feel free if you want to take these Alternating On/off posts from the Wishlist thread and make a separate thread out of them...
Time to play with the new feature~

Cheers

No worries, this is exactly what this topic is for.

But you're right, we should have a separate topic for alternating on/off intensity discussion. Feel free to create one. On the other hand, there's a nice discussion here

on Ti in Quartz, which would also be appropriate.

I would be interesting to have the user be able to define what is possible in terms of a _low_ Faraday cup current. Currently, it seems that if PfE reads any FA measurement below 1.000 nA, it assumes the filament is blown (or some other non-starter). We would like to do some experiments with PfE using EDS with our SDD detector on beam sensitive materials using _low_ current, below 1 nA. Would you consider permitting a user, say in the probewin.ini file, to set, the lower limit on when PfE issues "your filament is shot" type of comment?

Hi John,
It's already there in the Probewin.ini file under the [faraday] section:

[faraday]
MinimumFaradayCurrent=0.1

The default is 0.1 nA so maybe you changed it at some point?

Hi,

just curious. Would it be possible to have Picture Snap as a standalone utility? It gets a lot of use in my lab even when we don't use PFE (like for example with the EDS software). I always have to show the users how to open PFE, create a file etc just to get to PictureSnap. This is obviously not a very big problem but I thought I might ask.

Hi Anette,
Your best bet would be to simply run the Stage utility, as it has PictureSnap also.

Smart! Will do.

Thanks?

Ok, I will hide my question here as I think I am just missing it (I think I may have even asked this before). Are there probewin.ini keywords to turn on/off:

Automate window: Use confirm during acquisition
Peaking options window: Acquire automated pha scan after peaking
Peak/Scan options: Use ROM based spectrometer scanning
Acquisition options: Quick Standard Acquisition modes (Assigned/Assigned or Major Elements)

Thanks!

Are there probewin.ini keywords to turn on/off:

Automate window: Use confirm during acquisition

Yes.

[Software]
UseConfirmDuringAcquisitionFlag = 0     ; 0 = off, 1 = on

Peaking options window: Acquire automated pha scan after peaking

No. But the flag is saved to your MDB file for each run.

Peak/Scan options: Use ROM based spectrometer scanning

Yes.

[General]
PeakCenterMethod=2     ; 0 = interval halving, 1 = parabolic, 2 = ROM, 3 = manual

Acquisition options: Quick Standard Acquisition modes (Assigned/Assigned or Major Elements)

No.

Could be added though...

Hi,
Would it be possible for PfE to check to see if the reflected light is on (and turn it on if necessary) before doing an autofocus and the turn it off again after the autofocus?
or is this already implemented somewhere?
This would be useful when automatically acquiring backscatter images after each analysis.
Thanks!

Easy peasy!

I am doing it for all the other instruments, but forgot to do this for the 8x30 instruments!

Thanks John! Awesome service

Thanks John! Awesome service 

You are most welcome.

Please try the test Probewin.exe in the PFE Dropbox.

Hi John,

Just trying the new version with the auto light on and off with autofocus. Nice feature, but can you i) add a delay, of at least a second if not 2, to the the autofocus start allow the light to come on (its a bit too quick off the mark at the moment and tries to focus in the dark so sometimes misses finding focus), and ii) add the option to either toggle the light or not - it's great when running samples, but a bit of a niusance when trying to confirm standard positions and just as you're about to adjust the position the light goes out .
