Get Beam-line Calculator old version APK for Android
Help Synchrotron Radiation users calculate their daily used parameters
A very useful app that could be used to calculate: Reachable diffraction angle for a given detector size and sample to detector distance(note: the "sample to detector distance" was named "Camera length" in the app!), Energy, Bragg d-spacing, wavelength independent q value, Ruby fluorescence/pressure, and do a X-ray Fluorescence lines lookup.
Can work offline and help you quickly complete the calculations!! A Good tool for High pressure(HP) experiment!
