Main Page

These are the official Wikipedia pages for the now digital and previously analog Gammasphere Data Acquisition systems (GS DAQs). Procedures for running the DAQs and the data format will be documented here, as well as details of the hardware and processes of Gammasphere.

The GS DAQ serves the Gammasphere detector array, located at the ATLAS accelerator, home of the CAlifornium Rare Isotope Breeder Upgrade (CARIBU).
