xHREMTM: HREM Simulation Suite

New Version (v3.5) is avairable now!
xHREMTM (WinHREMTM/MacHREMTM) is a suite of the high-resolution electron microscope (HREM) simulation programs that will run under both Windows and Max OS. This emerges from the HREM image simulation programs based on FFT multislice technique developed at Arizona State University, USA. This is one of the most reliable and efficient HREM image simulation programs in the world.
xHREMTM has been developed for the image simulation for Transmission Electron Microscope (TEM) and enforced by two options used to simulate Convergent Beam Electron Diffraction (CBED) and Scanning Transmission Electron Microscope (STEM), respectively. Please consult each catalog listed below for more information.
This version supports a multi-CPU machine and optimized for computing speed by using Intel's Math Kernal Library (MKL). Thus, we recommend to use this version especially for a STEM simulation.
Evaluation Version of the next release (v3.6) is avairable now!
From this version two new variatnts will be released, namely "STEM Extension Cluster" for a Clustered PC, and "STEM Extension Pro" for a 64-bit OS. These variatnts allow a STEM-HAADF simulation of a large model.
