NaI(Tl) Detector Anti-Coincidence Arrangement with two HPGe Detectors in Coincidence


 

 

Example for a result using a LOAX-typ

 

Anti-Compton pulse-height distributions with a Br-82 point source on the endcap of a HPGe detector (crystal dimension: 7 cm diameter, 3 cm thick) without and with anti-coincidence

The Compton suppression for a 3 to 4 γtransition to the ground state is about "50" at 1 MeV, "97" at 180 keV and also "50" near 64 keV

The Present Reference!
