PressureCalculator

PressureCalculator is a free Windows application for determining pressure in high-pressure experiments (such as diamond-anvil-cell experiments). It supports three complementary methods:

  • Ruby fluorescence : pressure from the shift of the ruby R1 fluorescence line, with several published ruby scales and a temperature correction.
  • Diamond Raman edge : pressure from the high-frequency edge of the diamond anvil Raman band.
  • Equation of states (EOS) : pressure from the measured lattice constant (or unit-cell volume) of standard materials such as gold, platinum, NaCl, periclase, and others.

Measured spectra can be loaded from text files, smoothed, and fitted directly in the application; see Spectra and fitting.

Installation

Download the latest release from the GitHub Releases page.

File Description
PressureCalculator-setup.msi Recommended. Installer for ordinary (x64) Windows PCs.
PressureCalculator-setup_arm64.msi Installer for Windows on Arm (Snapdragon PCs, or Apple Silicon Macs running Windows via virtualization, etc.).
PressureCalculator-v.X.zip Portable (x64): no installation, self-contained. Suitable for PCs where you have no administrator rights.
PressureCalculator-v.X_arm64.zip Portable for Windows on Arm.

The MSI installer requires the .NET Desktop Runtime 10; if it is not installed, Windows shows a dialog with a download link on first launch. The portable ZIP packages bundle the runtime, so no separate installation is needed: just extract the ZIP to a user-writable folder and run PressureCalculator.exe.

PressureCalculator installs per-user (no administrator rights required) and stores its settings under HKEY_CURRENT_USER\Software\Crystallography\PressureCalculator.

Display language

The user interface is available in 11 languages. Choose Language in the menu bar and select a language; PressureCalculator restarts with the new language. This online manual follows the same language selection when opened from the application.

Online help

Press F1 (or choose Help → Online manual) in the application to open the manual page corresponding to the current mode.
