The extended range series promises to become the new Standard for germanium gamma detectors. It represents the best value fr dolar with an extended energy range of 10 keV to 10 MeV as compared to the 40 keV to 10 MeV range of the CP series. The ER Series is a rugged as the CP Series with a fully enclosed aluminum end-cap and offers the same neutron damage resistance as the CN Series.

All of this is possible because of technology breakthrough at Tennelec resulting in unprecedented yields of N-type material. We are prepared tos hare with you the fruits of our efforts in the form of a better detector at a better price.
