GeGI: identify, localize, and quantify any radioactive material

Pinhole Imaging Platform

Adds 60-degree pinhole imaging from 40 keV, below where Compton imaging works. The standard platform shields past the detector face and locks into the mounting channel; the tactical version cuts the kit to 8 lb.

Pinhole Aperture Inserts

Pb inserts that trade resolution against speed: 1 mm for the sharpest image, 5 mm for the fastest acquisition. The 3 mm insert ships with the Pinhole Imaging Platform.

Coded Aperture Imaging

Coded-aperture hardware for high-resolution imaging with mask and anti-mask acquisition. The automated version rotates the mask at intervals you set and offers 5 preset focal lengths for variable spatial resolution and field of view.

Tripod not included.

HRGe High-Rate Mode

A high-rate FPGA and software mode that keeps the GeGI 5 measuring at 1 to 2 Mcps, for process cells, holdup, and other high-flux work.

12-MeV Energy Scale

A factory front-end modification that extends the energy scale to 12 MeV while keeping a 64k-channel spectrum, with conversion gain variable by factors of two. Reaches the high-energy gammas standard scales clip.

Neutron Counter

Adds thermal-neutron counting alongside gamma spectroscopy. Micro-structured semiconductor detectors with 6Li conversion reach about 30% thermal-neutron detection efficiency.

External Start Signal

A coaxial input that time-stamps your external trigger on the same 50 MSPS clock as the imaging and spectroscopy data: 20 ns resolution for coincidence measurements, with up to 1374 s between resets.

Preamplifier Signal Access

32 MMCX connectors expose the raw preamplifier signals for your own readout electronics, with per-strip switches selecting internal or external processing. Can be added any time after delivery.

GM Tube Dose-Rate Extension

Above roughly 5 mR/hr the instrument switches to the GM tube automatically and keeps reading dose rate to 1 Sv/hr, so one tool covers both survey and high-dose entry.

Internal Battery Kit

Hot-swappable internal Li-ion batteries, 2 batteries and 1 charger per package. Each battery provides about 4 hours of field operation on the Fulcrum and 2.5 hours on the GeGI 5.

External BB-2590 Battery Kit

External BB-2590 Li-ion battery package: 2 batteries, 1 charger, and cables, for powering the instrument for extended periods on battery. Each battery provides about 4 to 5 hours of field operation.

Pelican Shipping Case

Pelican shipping case for the instrument and its accessories.

Lightweight Tripod

Lightweight tripod to support the instrument. The GeGI 5 version includes a base plate for pinhole imaging; manual operation.

GeGI tripod requires the Pinhole Imaging Platform.

Automated Pan-Tilt Head

Automated pan-tilt head for the GeGI 5: remote-controlled motorized panning and tilting of the GeGI on the tripod.

Requires the lightweight GeGI tripod.

Radiochemistry Cart

Heavy-duty cart for the NP Imager and GeGI. Includes an aluminum channel for Pinhole Zoom, a motorized lifting mechanism for the variable pinhole plate, and an onboard power strip.

Laptop and pinhole aperture ordered separately.

Laser Range Finder

Laser range finder with mounting bracket for the GeGI 5. Bluetooth connectivity simplifies range input into the imaging software.
