Hi Folks, I was fortunate enough to have a summer student this crazy summer and had them work (from home, of course!) on web applications for X-ray data resources, including absorption calculations for materials. The result is a bit like a web version of Hephaestus and is currently at both https://xraydb.xrayabsorption.org/ and https://millenia.cars.aps.anl.gov/xraydb/ While similar to Hephaestus, there are some differences too. There are pages for absorption and fluorescence lines, absorption length calculations, ion chamber flux calculations, mirror reflectivities, scattering factors, and mono Darwin widths. Many of the calculations will show interactive plots, links to data, and/or a link to a python script to reproduce the calculation. Questions, comments, complaints, or suggestions for making this better are most welcome. We may have missed your favorite Hephaestus feature - is so, please let us know. Also: the X-ray Data Library - a collection of XAS spectra - has moved to https://xaslib.xrayabsorption.org/ https://xraydb.xrayabsorption.org/ This has also expanded some (well, now with about 270 spectra), and added several features, notably interactive plots. Again, any comments or suggestions for making this better would be most welcome. I will be adding more data to this library, but I also ask that if anyone has data they can and would like to share on this site, please let me know. Thanks for any feedback or suggestions you might have. --Matt
