Aegis portable high-purity germanium spectrometer is Mirion's latest mobile, battery powered HPGe gamma spectrometer. Compared to Falcon5000 ® Like its predecessor, it offers many state-of-the-art technological features such as a heatless cycle low-temperature thermostat, integrated design, and laboratory grade energy resolution. However, all of these combine an IP65 protection rating, larger high-purity germanium crystals, and the option of providing a remote detector chamber (RDC) low-temperature thermostat for portable spectrometers. (Enable detector anti shielding). In addition, the Aegis system is 12% lighter than the previous Falcon 5000 system. All these features make the Aegis spectrometer easy to deploy and can be used multiple times in the field and laboratory.
