The Doctrines of Grace as seen and needed by a nuclear physicist
Monday, April 22, 2013
Technicians are building and testing equipment needed to support the Jefferson' Lab's newest (and fourth) experimental hall – Hall D. (My research is mostly in Hall B, a little in Hall D). Shown here are Hall D fADC250 readout electronics VXS crates (with blue pieces) and the high-voltage chassis (red). The Jefferson Lab-designed fADC250's are flash analog-to-digital converters. They take data at a rate of 250 million samples per second on each input signal (there are 16 inputs per board) simultaneously. Experiments in Hall D are scheduled to begin in 2015.
