This is an old thread but I should bring it up to date a bit. First I wanted to note that our latest Probe for EPMA/Probe Image customer is the Belgian Nuclear Research Center (SCK-CEN) in Belgium on their SX100R:
http://probesoftware.com/Customer.htmlThis is a shielded instrument designed by Cameca specifically for analysis of nuclear materials. Philippe Poeml was instrumental in helping to set up this installation up in their controlled area laboratory, since access is difficult for nuclear sites such as this. In addition Philippe provided for them his carefully prepared x-ray and MAC x-ray tables which have been optimized for actinide characterization. I have attached them as a ZIP file below (remember to login to see attachments).
To take advantage of Philipp's actinide optimized files (which will work for CalcZAF as well), simply unzip the files and copy them to the Probe for EPMA ProgramData folder (usually C:\ProgramData\Probe Software\Probe for EPMA) and overwrite the existing files. Note that normally Microsoft makes the ProgramData folder a hidden folder, so one might need to make this hidden folder visible using the View | Folder Options | View tab in Explorer.
Also, because the actinide MAC values are tabulated in the USERMAC.DAT file, one needs to select this as the default MAC file for calculations of nuclear materials. This is easily done from the Analytical menu in PFE (or CalcZAF), but if one works with nuclear materials often, one can set the default in the Probewin.ini file (also in the ProgramData folder), by editing this line as seen here:
MACTypeFlag=7 ; default MAC file (1 = LINEMU, 2 = CITZMU, 3 = McMaster, 4 = MAC30, 5 = MACJTA, 6 = FFAST, 7 = USERMAC.DAT
Thank-you to Philipp Poeml for his expertise and hard work in developing these nuclear optimized x-ray and MAC files.
