    Custom scintillators and probes

    Scintillation detectors usually employ a Voltage Divider (VD) network to operate a Photomultiplier Tube (PMT). This network (sometimes referred to as a "bleeder network") defines the potential (voltage) differences between the cathode, dynodes and anode of the PMT. The exact design of this network is significant for optimization of the scintillation detector. Some details of voltage divider networks are discussed below. The descriptions below are not exhaustive; for more details we refer to the photomultiplier manufacturer's literature... Read more

    CeBr3 High Resolution / Low Background Scintillators

    CeBr3 crystals offer an alternative to NaI(Tl) and other high resolution scintillators for gamma spectroscopy applications. CeBr3 scintillation crystals are characterized by their high resolution, fast decay time, and low intrinsic background properties. With a background count as low as <0.001 c/cc/s in the Ac-227 complex, CeBr3 presents a distinct advantage over other high resolution... Read more

    Anti Compton Shields

    Compton Suppressors or Anti-Compton Shields (ACS) are used to suppress unwanted background in gamma spectrometry performed with Ge detectors. The detection of low intensity gamma ray lines is complicated in spectrometry performed with High Purity Germanium (HPGe) detectors by the presence of Compton scattered gamma rays of higher energies. At energies above a few hundred keV, the main... Read more

    (SiPM)

    Silicon Photomultipliers (SiPMs) offer an alternative to the readout of scintillation crystals with Photomultiplier Tubes (PMTs). SiPMs are especially ideal in applications where a compact package and low voltage operation are crucial. The energy resolution and noise level achievable with SiPM readout varies with the type of scintillator, crystal dimensions, and the surface area covered by the... Read more

    Scintillation Detector with Spectroscopic Amplifier and Single Channel Analyzer (SCA)

    Large volume scintillation crystals can be coupled to Photomultiplier Tubes (PMTs), or Silicon Photomultipliers (SiPMs). Both methods can be integrated in detector assemblies with front-end electronics. Assemblies can be constructed with integrated, or demountable PMTs, terminated in 14 pins, or they can be constructed with a complete set of electronics. Also, large volume scintillators can...
