HPGe Radiation Detector Options and Accessories

  • Detector Add-on Options +


    Integrated Cryocooling System Option (-ICS, -ICS-E)
    The Integrated Cryocooling System (ICS) cryostat is sealed with a cryocooler and is immune to thermal short cycling. Unlike the typical three day loss of use of the detector with a standard type cryostat, the ICS can be re-cooled immediately, minimizing any time lost for temporary warm up. The ICS is available with an internal preamplifier (-ICS) or an external preamplifier (-ICS-E). 
    Compatible Detector Types for -ICS: GEM
    Compatible Detector Types for -ICS-E: GEM, PROFILE, GMX

    Integrated Cryocooling Low-Background System  (-ICS-LB)
    Low-background detector with internal preamplifier, high purity aluminum endcap, high purity aluminum window, high purity aluminum internal cup, and low-background Cu mount for the ICS Integrated Cryocooling System. The lower background material allows for lower Minimum Detectable Activity (MDA) for a specific counting time, which provides another step in increasing sample throughput in low-background applications.
    Compatible Detector Types: GEM

    SMART-1 Option  (-SMP, -SMN)
    The SMART-1 option monitors and reports on vital system functions, and can save authentication codes and report the code at a later time. It has the high voltage included, so none of the instruments require an external high-voltage power supply. The SMART-1 is housed in a rugged ABS molded plastic enclosure and is permanently attached to the detector endcap via a molded-strain-relieved sealed cable. This eliminates the possibility that the detector will suffer severe damage from moisture leaking into high-voltage connectors. The SMART-1 can be positioned in any convenient place and does not interfere with shielding or other mounting hardware.
    Compatible Detector Types for -SMP: GEM, PROFILE, Safeguards GEM, Actinide-85
    Compatible Detector Types for -SMN: GMX, GLP, Safeguards GLP

    Ultra-High Count-Rate Preamplifier Option  (-PL)
    The Ultra-High Count-Rate Preamplifier (transistor-reset preamplifier), can handle input count rates up to 1,000,000 counts/s at 1 MeV and offers the added benefit of having no feedback resistor.
    Compatible Detector Types: GEM, PROFILE, GMX

    Harsh Environment Option  (-HE)
    The Harsh Environment option is a rugged carbon fiber endcap with a sealed electronics housing featuring a replaceable desiccant pack which ensures that the electronics stay 100% dry and indicates when it needs to be replaced. GEM series detectors in PopTop capsules of 76 mm diameter or larger can be supplied with this option. 
    Compatible Detector Types: GEM, PROFILE, GMX

    Remote Preamplifier Option  (-HJ)
    This option allows all the preamplifier and high voltage connections to be outside a shield and removes the preamplifier and high voltage filter from the “line-of-sight” to the Ge crystal. For low background applications, this option eliminates any possible preamplifier or high voltage filter components that may add to the background inside a shield.
    Compatible Detector Types: GEM, PROFILE, GMX, GWL

    Low-Background Carbon Fiber Endcap Options  (-RB, -LB-C, and -XLB-C)
    The Low-Background Carbon Fiber Endcap is as strong as Al, Mg, and Cu, creates less background, does not corrode, and can detect energies less than 10 keV. This lower background material allows for lower Minimum Detectable Activity (MDA) for a specific counting time, which provides another step in increasing sample throughput in low-background counting applications. The lower Z of Carbon Fiber provides a low-energy window without the additional background found in most alloys.
    Compatible Detector Types: GEM, PROFILE, GMX

    Low-Background Be/Cu Endcap Options  (-RB-B, -LB-B, and -XLB-B)
    If the ultimate in low energies is required, a low-background, high purity Be window can be installed in a Cu endcap to minimize the background and still allow energies as low as 3-keV through the front window of the detector.
    Compatible Detector Types: PROFILE, GMX

    Beryllium Window Options  (-B)
    Provides improved performance between 3 and 5 keV.
    Compatible Detector Types: PROFILE

    Aluminum Window Option  (-A)
    An all aluminum endcap can be chosen if the energies of interest exceed 20 keV. 
    Compatible Detector Types: GMX

    Carbon Fiber Window Option  (-CW)
    A carbon fiber window is available for energies greater than about 8 keV. While this window does not pass all the lower energies, carbon fiber has lower Z than Al and does not have any of the hazards associated with Be.
    Compatible Detector Types: GMX

    Low-Background Well  (-LB-AWT, and -XLB-AWT)
    Low-background Well detectors are supplied with oxygen-free high conductivity (OFHC) copper endcaps with low-background high purity aluminum well tubes of 0.02 inch wall thickness.
    Compatible Detector Types: GWL
