The RHEED software SAFIRE is a powerful and easy to use RHEED evaluation tool. It combines sophisticated evaluation algorithms with extensive opportunities for data representation and documentation. SAFIRE can handle an arbitrary number of parallel measurements and offers fast real-time data exchange with MBE controller for closed feedback loop operation. Multiple measurements can be stored in the same display for comparison. The temporal resolution in all measurement modes is 20 ms, Kikuchi line analysis, azimuthal scans, integration with 16 bit resolution and on-chip-integration keep you at the forefront of RHEED research.


  • Exposure time: N x 2ms (analog), 1-10000ms (digital)
  • Sensors: Unlimited number and shapes
  • Point scan: Integrated intensity of sensor versus time
  • Line scan: Intensity along line versus time

SAFIRE Ultimate

The Safire Digital Ultimate system features the brand new pco.edge camera. With a resolution of 5.5 megapixels, extremely low noise, a frame rate of 100 fps and a dynamic range of 22,000 : 1, Safire Digital Ultimate defines the new gold standard for RHEED image acquisition systems. With more than four orders of magnitude dynamic range, intensity variations similar to x-ray diffraction measurements can be captured with a single exposure. At the same time, the ultrahigh spatial resolution allows you to catch the shape of even very sharp peaks in the pattern with enough data points to allow fitting. And all this is possible with more than enough time resolution to catch fast transient features during growth.
