Nab Silicon Detectors

Nab is an experiment to measure the a and b parameters in neutron β decay. This experiment requires two large area silicon detectors, designed at Los Alamos National Laboratory. The silicon detectors use thick single-crystal silicon sheets between 0.5 mm and 2 mm thick.

"A cross section view of the silicon detector. The Si wafer is 12 cm in diameter. The planned experiments will be carried out with 2 mm thick detectors. The 16.6 cm diameter ceramic disc that is attached on the ohmic side of the Si wafer is not shown in the figure."
