HPGE WELL DETECTOR

PGT well detectors are ideal for efficiently analyz-
ing small, low-activity samples. Spectra acquired
with a through-hole PGT well detector exhibit bet-
ter energy resolution and improved minimum de-
tectable activity values. This improved performance
is a direct result of the PGT “through-hole” design.
Much has been written about the supposed superi-
ority of blind hole detectors because of their nearly
4-pi geometry. However, this is significant only for
a point source or very small samples. The blind
hole was the original configuration used by PGT to
manufacture its first Ge(Li) well detectors circa
1968. But just as the Ge(Li) crystal has been re-
placed by the superior HPGe crystal, so too has the
blind hole design been supplanted by the through
hole design. There are a number of reasons why
this is a better design, but what proves it to be bet-
ter is detector performance
