There is a need for detecting nuclear materials
using small, low cost, low power microsystems.
Neutron Detection Microsystems
We have developed and demonstrated a proprietary method of detecting neutrons
that is 100 times smaller than other detectors, costs less, and requires less
power. This Neutron Detection Microsystem is also scalable to different sizes
depending on the needs of the application while maintaining high
sensitivity.
- Weapons Grade Plutonium emits neutrons.
- Reactor Grade Plutonium emits more neutrons.
- Highly Enriched Uranium emits neutrons if stimulated with a neutron
source.
Two designs are shown below:
1.5 Cu. In. Personal Neutron
Detector
10 Cu. In. Container Neutron
Monitor
256-Channel Gamma Spectrometer Microsystems
The low power, 256-channel gamma spectrometer microsystem uses a CdZnTe
detector along with a unique, Sandia designed, low noise, analog pulse
processing ASIC and a few commercial parts. The spectrometer operates at room
temperature with no cooling required, is 2 cubic inches in size, and runs on
about 50 mW of power. The ability to measure spectrum enables the type of
nuclear material to be identified on the spot. The picture below is a test
board.
