CASS—CFEL-ASG software suite

The Max Planck Advanced Study Group (ASG) at the Center for Free Electron Laser Science (CFEL) has created the CFEL-ASG Software Suite CASS to view, process and analyse multi-parameter experimental data acquired at Free Electron Lasers (FELs) using the CFEL-ASG Multi Purpose (CAMP) instrument Strüder et al. (2010) [6].The software is based on a modular design so that it can be adjusted to accommodate the needs of all the various experiments that are conducted with the CAMP instrument. In fact, this allows the use of the software in all experiments where multiple detectors are involved. One of the key aspects of CASS is that it can be used either ‘on-line’, using a live data stream from the free-electron laser facility’s data acquisition system to guide the experiment, and ‘off-line’, on data acquired from a previous experiment which has been saved to file.Program summaryProgram title: CASSCatalogue identifier: AEMP_v1_0Program summary URL: http://cpc.cs.qub.ac.uk/summaries/AEMP_v1_0.htmlProgram obtainable from: CPC Program Library, Queen’s University, Belfast, N.
