Astronomy and astrophysics labs use high-speed digitizers for the capture of data. Experiments include observation of fast gamma radiation through secondary (Cherenkov) light, that requires multichannel coincidence measurements, or RF/uw recording as a function of time.

Multiwavelength Study of TeV Blazar Mrk421 During Giant Flare and Observations of TeV AGNs with HAGAR.
The High Altitude Gamma Ray (HAGAR) telescope is run by the Indian Institute of Astrophysics. It is an Atmospheric Cerenkov experiment with 7 telescopes each with a UV sensitive photo-multiplier tube (PMT). This paper describes the use of this
arrangement, which also includes Agilent Acqiris high-speed digitizers for observation
of Cherenkov light from TeV gamma-ray-emitting blazers, and a radio galaxy.

The ARGOS FFT radio spectrometer used to detect and to measure molecular lines ubiquitous in star forming regions, planetary and cometary atmospheres. At its heart is a real-time Fast Fourier Transform (FFT) embedded into the FPGA of an Agilent Acqiris high-speed digitizer running at 2 GB/s. This paper describes the implementation of this device, and measurements made at the KOSMA telescope.Tags: astrophysics high-speed digitizer share
