A database for fast access to Particle-Gated Event data

In nuclear physics experiments involving in-flight fragmentation of ions, usually a large number of different nuclei is produced and various detection systems are employed to identify the species event by event, e.g., by measuring their specific energy loss and time of flight. For such cases – not necessarily limited to nuclear physics – where subsets of a large data set can be identified using a small number of measured signals, a software for fast access to varying subsets of such a data set has been developed. The software has been used successfully in the analysis of a one neutron knock-out experiment at GANIL.
