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.
Key Features
- ZoomFactor magnifies source distributions from a fixed instrument position
- Optional gantry positions the detector head to accommodate the geometry of any hot cell or bench setup
- Resolves and quantifies individual isotopes along the column
Accessories
Options and field kit for the NP Imager
Capability upgrades
2Options that add a measurement mode to the instrument.
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.
Field kit
4Power, shielding, mounting, and transport that keep the instrument measuring through a full shift.
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.
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.
Spares & consumables
2Replacement parts and per-measurement supplies.
HEPA Filtration
HEPA filter adapters, brackets, and replacement filters. The adapter attaches with 4 screws; the filter is taped in for easy disposal after measurements.
Pinhole Mounting Channel
Aluminum base plate and channel with locking points for proper positioning of the pinhole apertures and GeGI. Includes a tripod attachment point.

Technical Notes
Methodology
How reliable are PHDS mechanical coolers? Field data from 1,300 cooler-years
Counting every repair return as a failure, field data from 264 PHDS coolers supports a cooler MTTF of 1.8 million operating hours: about a 0.4% chance of a repair in any year of service.
