The (Passivated Implanted Planar Silicon) PIPS detector that we purchase for our beamlines is model: PD 3000-55-300-AB AB is for BNC connector, if not specified they mail it with an AM (Axial Microdot) connector. PD is partially Depleted, 3000 mm square is the area of the detector. 55 KeV (FWHM) is the energy resolution for alpha particles, and 300 is the thickness of Si in microns.

PIPs detectors
by Bruce Ravel 09 Nov '09

09 Nov '09

Hi all, A colleague at a company that, for some reason, blocks mail from this mailing list asked me a question the other day that I don't have an immediate answer for. I told him I would pass his question along to the list and forward him any answers. He asks: I've looked over the Canberra website, but I am a little confused about what specifications I should go for. To be absolutely honest, I have never seen a PIPs detector/chip in person as they have always has the Al/Mylar film attached. Would you happen to have a specifications/model list for one of these devices (and the requisite type of BNC connector that I need)? I would greatly appreciate any direction that you could offer.

modeling anti-site disorder
by Shashwat 08 Nov '09

08 Nov '09

Dear All, I am studying the local disorder caused in CoGa alloy (B2: CsCl structure) due to ball-milling; it is expected that Ga atoms substitute most of the Co atoms in the Co sublattice after prolonged milling. In order to model this "anti-site" disorder (occupation of Ga atoms on the Co sites) in ATOMS, I am considering to change the occupancies at the corresponding sites as given below: Before ball-milling: site a: occupancy of Ga = 1 site b: occupancy of Co = 1 (standard .cif data) After ball-milling (assuming 80% anti-site concentration): site a: occupancy of Ga = 0.2 (plus compensating vacancies) site b: occupancy of Co = 0.2 site b: occupancy of Ga = 0.8 Could anyone suggest if this approach is reasonable. Many thanks ... Regards, Shashwat

Re: [Ifeffit] Ifeffit
by Matt Newville 06 Nov '09

Hi Clement, I don't have any experience with the windows emulator on Mac OS X, and have only heard reports that it does work. When running atoms.exe on the Windows emulator on Mac OS X, you see: Running "C:\Program Files\Ifeffit\bin\atoms.exe" MetaCinn.inp '\\.host\Shared Folders\Desktop' CMD.EXE was started with the above path as the current directory. UNC paths are not supported. Defaulting to Windows directory. MetaCinn.inp: not a valid input file for Atoms. My guesses are: a) you want to run atoms in a directory without a space in the name b) you want to be sure that the file is has Windows line endings, not Mac OS line endings. Those are guesses, so I'm also CC'ing this to the Ifeffit mailing list, as someone there may have experience with this issue. --Matt 2009/11/5 Clément Levard <clevard(a)stanford.edu> > > Hi Matt, > I am a new postdoc in Gordon Brown's group in Stanford and would like to use you package for XAS analysis. > I am working on Mac, have installed a Windows Emulator.

Two absorbing atom sites
by Yun Luo 05 Nov '09

05 Nov '09

Dear IFEFFIT List, I learned that IFEEFIT can model a single absorber in two different environment. Could anyone direct me to similar studies that have been done or related tutorials? Below are some thoughts and questions: For example, there is 2 wt% A in both M1 and M2 structural sites in crystal X as dopant. I first create 2 FEFF models in Artemis, one has absorbing atom A only in M1 site and the other one has A only in M2 site. In the fitting process, is it correct that I choose paths from both FEFF models and using different Eo and So^2 for M1 and M2 sites? And to model the site occupancy of A in each site, I can create a fraction parameter "a" (which means there are a*2 wt% A in M1 site and (1-a)*2 wt% A in M2 site). Is it correct to apply this fraction parameter only to So^2 to model the site occupancy of A in M1 and M2 site? I am worried this approach will use too many variables. Any suggestions on the constraints/restraints that I can use? Finally, is there anything else that I missed which needs to be considered to do the modeling for this case of two different absorbing atom sites? Any suggestion will be greatly appreciated! Thank you all in advance! Best regards! Yun
