Hello Leon, I frequently use the easyXAFS instruments in Pacific Northwest National Laboratory. If samples are well made, then even the troublesome fluorescence lines can be managed and cancelled out during the data processing once you collect both It and I0 at the same power making the dead time and count rate to match. This is a paper I published where we collected XAS data both in the lab and APS: Boglaienko D, Andersen A et al X-ray absorption spectroscopy of trivalent Eu, Gd, Tb, and Dy chlorides and oxychlorides. J. Allows Compounds. 2022. Also, easyXAFS company has an excellent customer support.

Dear Leon, you can request the publications relative to easyXAFS here (it takes a few minutes to receive them): https://www.easyxafs.com/copy-of-links I am currently analyzing XAFS data from that instrument and I can tell that the data in the XANES region look good in terms of signal-to-noise ratio, also collecting them for just 1 hour. To get sufficiently good data in the EXAFS region would need much longer data collections. One annoying disadvantage is coming from spurious fluorescence peaks from the standard X-Ray tubes used. The measurable elements and edges are limited, of course.

Deglitch the data
by Shailendra 16 Jul '23

16 Jul '23

Hi, IFEFFIT community, I am Rachna, a Ph.D. student working on IrO2 based OER catalyst. I am a new XAS user. Recently, we recorded some XAS on amorphous IrO2 electrode samples however some of the samples show a dip in adsorption at high energy. The glitches are similar to the one in the attached photo. I am attaching the Athena file for the measurements too. I was wondering if there is a way to remove such glitches. I would greatly appreciate any tips or tricks you may have for dealing with this situation. Thanks, Kavya Rachna

Re: [Ifeffit] Help installing Demeter on a Mac
by Fowler, Joseph W. (Assoc) 01 Jul '23

Hello Kyle, I agree that putting /opt/local/bin in your PATH should be adequate, so this isn’t totally obvious. The executables athena, hephaestus, and artemis should all be in /opt/local/bin/. Are they? What is the result if you execute the following? $ port contents demeter I’m the official maintainer of the Macports version of Demeter. Unfortunately, I’m not a regular user. In fact, it’s not installed on the everyday computer that I’ve had for four years (to give you an idea of what “not regular” means to me). Worse, there’s a chronic problem that I have never worked out how to solve. The Demeter ports depends on many things. One is ifeffit, which is not really still supported, but Demeter can’t just magically start using Matt Newville’s replacement for ifeffit, known as Larch. It feels to me like Mac-Demeter is doomed to break permanently pretty soon, if it has not already. [Bruce, Matt, have I stated that accurately? Please correct me if I’m wrong.] Still, there exists a port for ifeffit and for demeter, and one should be able to install them. I’m trying it right now on a Mac that lacks them. It will take me a while, because I’m not a Perl user either, and there are dozens of dependencies to install first. Let’s see how it goes for me… This install is taking a very long time. I’m going to send this note as-is and report later about whether I can make athena run, and where the executable is located. (But I’m sure it will be /opt/local/bin/ ) Could I suggest that, if you get it to work, and you use it regularly, and you’re an open-source supporter, would you think about helping as a second official maintainer of the Demeter port? Other users could benefit from me teaming up with an actual demeter user, to be sure!

Dear subscribers: The information about the upcoming XAFS short course is here: https://www.bnl.gov/xafscourse/ The course will be taught in-person. The place in the course is limited, and, due to the emphasis on advanced methods, the preference will be given to those participants who have prior experience with EXAFS data modeling and analysis. The info about the past course topics (2005-2022) is at the SCC website: https://you.stonybrook.edu/scc2/xafs-workshops/ Regards, Anatoly ------------------------------------------------------------------- Anatoly I.
