Position-Sensitive (Imaging) Detector of Neutron

Del Mar Ventures supply state of the art Neutron Imaging Detector NID2000.
Neutron Position-Sensitive detection is realized by registration of luminescence generated by neutrons passing Gd-doped screen using MCP based image intensifier and CCD detector. NID2000 detects neutron fields in real time and can be used for many "on-line" (in field) monitoring applications.

Specifications:

Gd-doped luminescent screen made of powder luminophore (Gd2O2S: Tb) for thermal neutrons and
composite material consisting of an organic resin and a powder luminophore (Gd2O2S: Tb) for fast neutrons

Sensitive area diam. 30 - 350mm, other sizes available on request

CCD matrix 1000x1000 cooled by two-stage peltier (thermoelectric) cooler

Ultimate spatial resolution up to 30mm for thermal neutrons, about 1mm for fast neutrons

Detection efficiency - for thermal neutrons ~ 60%
                                2.5MeV neutrons (D-D reaction) ~ 1%
                                14MeV neutrons (D-T reaction) ~ 0.25%

Dynamic range - 14 bit

Detector size (for diam.150mm screen) ~ 400x400x1000mm

The complete NID2000 system comprises a luminescence screen, MCP intensified CCD camera, camera controller, PCI interface card and software running under Windows™.
We supply Basic software package NI2 as well as Tomographic Reconstruction Software NT3.
