It's either closer to betafite or uranopyrochlore, but sure does not look like brannerite. ________________________________ Sent: Monday, February 10, 2020 5:33 AM To: [email protected] <[email protected]>;

Charles run a gamma spec on this. Note the low energy tail on the U is it possible there is some Th in there? I can’t pick out energies off the jpg post the MCA file. Dud Sent: Monday, February

Geo, I agree Geo its busy, confusing and adds nothing. It would be nice to turn off any elements that are not ID’d as It messes up the energy grid lines, and is confusing about what’s actually

haha. I've heard stories about the voracity of those rock-shop labels. Hey mineral guys, a question. How common is thorium in USA? Does it always come with U or is it also alone? ThanksGeo>K0FF

Good, thanks and it looks fine, keep it up. I did my first 24 hour run with Si-PIN in Gamma Scan mode (no XRF exciting from internal or external) on one a weakly radioactive target over the weekend

OK, guys, I shall have to revisit my sample - gamma spec. It never occured to me to try XRF with it, but likely need to configure more than one AM-241 pill for that. Has anyone tried using the old

I picked this up yesterday. It was interesting because Brannerite UTi2O6 is supposed to be high in Ti and less so in Ta and Nb like betafites (Ca,Na,U)2(Ti, Nb,Ta)2O6Z(OH). However, this specimen

Yes, that is correct, George. The heavy black lines are what I consider firmly identified. I normally expand the lower region and leave off the Bremsstrahlung and 59.5 peak to the right. I never

Hi A Wally! What you have is exactly what I have when it comes to 662 etc. Anything over 100 keV and I'm right back on the UCS-20 with a 2X2 Scionix and feel darned lucky to have it. When you do get

nice outfit Dud, and I suppose the filters are inside or are they outside, and they are only in the beam path not the sensor path correct?And I know the program expects certain filters as supplied?

Nice display, the Fe Kb1 line is well placed. Have you expanded the? X-axis to include 59.5 yet? I'm interpreting the vertical black dotted lines are pretty certain and the lighter, smaller lines are

I think it depends on what you mean by "meaningful".? I have not tried XRF of Trinitite, but I have done some Gamma spec on my specimens.? I have used a Scionix 2x2NaI(Tl) probe with the UCS-20

Geo, The gun is set up w 3 beams 50, 40 , and 15 kV and depending on the mode it can use 5 filters. Filters are in on the 40 and 15 kV shots. Everything can be changed but The current is usually 11

Do the guns have adjustable V and current or are they one speed?Geo

Geo, For a full power 50 kV beam shot don’t use a filter. A filter is used to reduce the Brem above an elements absorption edge in order to get a better peak to background signal increasing the

Let's start with the Tel-X-Ometer These are self-contained X-Ray experiment stations, college level trainers and instrument. It has a 20 kVp/30 kVp switch selectable HV power supply, a hard vacuum

"Why are you running external filters?Dud"It's all about the Bremsstrahlung continuum. In the X-Ray tube electrons are accelerated by a HV field, then are slowed down by a target. Notice I didn't

Here is my latest best effort with trinitite using Am241 as an exciter. Only 3 elements really stand out: Fe U Ba. There are other possibilities such as Sn and Cs but I can't say for sure without a
