Miniaturized Gamma and Neutron Sensors

GR1 Compact CZT Spectrometer

GR1 Compact CZT Spectrometer

Description

The GR1 family offers high performance gamma spectroscopy in a compact, fully-integrated package. Designed for both laboratory and field use, this unit contains a preamplifier, shaping amplifier, baseline restorer, HV supply and MCA. The advanced signal electronics requires no cooling and provides ready access to spectroscopy data over the mini-USB port. The power consumption is less than 250 mW, so no external power is required. This makes the GR1 ideal for many portable spectroscopy applications where size, weight and power constraints are very important.

The 1 cm³ CZT detector provides gamma spectra with significantly improved FWHM resolution as compared to NaI scintillators. This greatly improves the identification capability for many important isotopes (such as Thorium and Radium daughters in the background) with closely spaced gamma lines.

The GR1 family includes four models, each with a 1 cm³ CZT solid state detector. The GR1 and GR1+ are provided in a clean rectangular package, with no external signal connectors (only the mini USB connector). The “+” designation provides an option for a higher performance detector (better FWHM resolution; see chart for details). The GR1-A and GR1-A+ are provided in the same rectangular package as the GR1, except that three MCX connectors are provided to allow access to the energy and timing signals as well as an input gate. These signals allow the units to be tailored for specific applications in nuclear research and academia.

LAB CPG – CZT Coplanar Grid Detector

LAB CPG – CZT Coplanar Grid Detector

Description

The Lab CPG detector offers a large volume CZT detector in a coplanar grid (CPG) electrode configuration. The application of the CPG electrode structure creates an electron-only collection device that allows for a reduction in tailing caused by the trapping of charge in the CZT crystal. This package provides superior detector performance ideal for typical radiochemistry laboratory applications where a high resolution and low background signal is paramount. The compact housing includes the detector element and preamplifier electronics. Connections on the back of the detector provide easy connection to both NIM-based and desktop MCA electronics.

SIGMA Compact CsI Scintillation Spectrometer

SIGMA Compact CsI Scintillation Spectrometer

Description

The SIGMA family is based on a CsI scintillator crystal coupled to a “state-of-the-art” SiPM (Silicon Photomultiplier) detector, high voltage, electronics and integrated MCA. All communication and power are provided over the mini-USB connector.

The SIGMA family comes in two scintillator sizes. The SIGMA25 has a 1 in³ CsI detector and the SIGMA50 has a 2 in³ CsI detector. All other aspects of the two devices are identical. Both units have a FWHM resolution specification of 7.2% at 662 keV, which is comparable to many NaI based solutions.

The profile of the SIGMA detectors makes them ideal for many portable spectroscopy applications where size, weight and power constraints are very important. The embedded MCA has a fixed number of channels, fixed high voltage and gain that provides a simple interface that is easy to setup and operate with essentially no configuration.

Features

  • All-in-one detector, electronics, and MCA
  • Includes CsI scintillator detector with SiPM (No photomultiplier tube)
  • Resolution better than 7.2% (at 662 keV)
  • Small overall size, but big performance
    • SIGMA25: 35 x 35 x 105 mm; 200 g
    • SIGMA50: 35 x 35 x 130 mm; 300 g
  • USB connection to PC
  • USB powered, 250 mW max
  • Interface to Genie™ 2000 software spectral analysis

Software

There are three software options available for use with the SIGMA detector series, two of which are offered as free downloads from our website.. Click here for a description of the software available and how to download it -->

TN-15 – High Sensitivity Ultra-compact Thermal Neutron Scintillation Detector

TN-15 – High Sensitivity Ultra-compact Thermal Neutron Scintillation Detector

Description

The TN-15 high sensitivity thermal neutron detector utilizes a state-of-the-art Silicon photosensor (SiPM) and offers world-leading specification in a compact form. The TN-15 surpasses the performance of a 100 mm long 13 mm 3He tube at four atmospheres. This highly compact device is completely self-contained, with a built-in preamplifier, shaping amplifier, pulse discrimination, and HV supply. The digitized neutron data is sent to a PC via the mini-USB which also powers the unit, so no external power supply is required.

Features

  • Surpasses the performance of a 100 mm long, 13 mm diameter He³ tube at four atmospheres
  • All-in-one detector, electronics, and MCA
  • Miniaturized package:
    131 x 33 x 24 mm, 110 g
  • USB Connection to PC for control and power
  • Power consumption: <250 mW

Software

The TN-15 comes with K-Spect, entry-level Windows®-based (XP/Vista/7/8) software built for detailed sample and spectral analysis. K-Spect, which is available to download, free of charge, from our website, provides the spectrum acquisition, display, analysis, and storage functions.
