Multiple EELS Acquisition

Category: Microscope & GIF
Description: This script will capture multiple EELS spectra and store them in a 3D EELS data cube. The EELS data cube is then processed to sum the spectra. Alignment and summation of spectra can be done with or without energy shift correction (to compensate for any energy drift). EELS data cubes can also be processed offline using the script 'EELS Cube Data Extraction', available at this site. Offline processing permits individual spectra to be extracted and spectra to be omitted from the summation. To use this script set up the spectrometer to display an EELS spectrum on the CCD - then run the script - enter exposure time, number of frames and any delay between frame capture. To remove X-ray spikes from the data, use the script 'EELS Cube Data Editor'.
Comments: This should work with any EELS system using a camera as a detector - the only system dependent line of code is the SSCacquire . . . command - edit this to suit your system. version 1.4 corrects some problems with missing tags, and some other minor issues.
