    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

    Anti Compton Shields

    Compton Suppression Shields are scintillation detector assemblies that are mounted around a High Purity Germanium (HPGe) detector to detect the gamma rays scattered by the Ge crystal when a Compton event occurs. Many options are available and careful consideration should be taken when selecting the scintillation crystal(s) and the assembly design. Please download our comprehensive application... 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

      CeBr3 High Resolution / Low Background Scintillators

      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 scintillators which suffer from this intrinsic activity. CeBr3 crystals are available either canned or fully assembled with... Read more
