These are the wiki pages for the Digital and the analog Gammasphere Data Acquisition systems (GS DAQs). Procedures for running the DAQs and the data format will be documented here.

The GS DAQ serves the Gammasphere detector array (http://www.phy.anl.gov/gammasphere/), located at the ATLAS accelerator (http://www.phy.anl.gov/atlas), home of the CAlifornium Rare Isotope Breeder Upgrade (CARIBU http://www.phy.anl.gov/atlas/caribu/).

Digitizer hardware features you probably don't know about

  • The digitizer has a DAC output.
  • The digitizer has a buffer amplifier that drives a copy of the analog signal going into channel 9 to outputs on the front panel. This is a simple analog buffer, no shaping, sampling or anything else.
