Portable Isotopic Neutron Spectroscopy (PINS) is an R&D 100 award winning technology employed originally to identify the contents of old munitions suspected of containing chemical agents. PINS Systems have been deployed world-wide since their introduction 10 years ago. Increasingly, PINS systems are being deployed as part of national counter-terrorist equipment providing a non-contact and nondestructive means of identifying the contents of
suspect packages. WHILE PINS EMPLOYS A NUCLEAR TECHNIQUE (NEUTRON
INTERROGATION), ITS PURPOSE IS NON-NUCLEAR: IDENTIFICATION OF CHEMICAL COMPOSITION. In miniPINS the original functionality and performance is retained, but in an easier to use, smaller, lighter and improved format made possible by improvements in software and in new digital electronics. PINS technology undergoes continuous developmental improvement under a collaborative agreement between ORTEC and Idaho National Engineering and Environmental Laboratory, U.S.A. (INEEL).1
In-field measurements require portability, reliability, and ease of use. The performance of the ORTEC PINS and miniPINS systems, has been verified in real-world use by the U.S. Army, which has successfully identified, in the field, hundreds of suspect munitions from burial sites and firing ranges. PINS readily and clearly distinguished between cylinders containing high explosives, cylinders containing blister agents and others filled with nerve gas. Recent international events have demonstrated the value of having such an instrument in the fight against terrorism. PINS systems have been deployed in support of a variety of security operations at more than 40 sites in the U.S.A. and elsewhere. MiniPINS represents a number of experience-based improvements. The physics, of course has not changed!
Principle of Operation: The Physics
PINS is a novel application of a well-understood technique, involving the interrogation of a container, using neutrons from a small moderated source. The neutrons pass through the wall of the container and collide with the atomic nuclei of the contents.
The ensuing nuclear reactions (neutron capture and inelastic scattering) produce gamma rays, which when appropriately detected and recorded, produce a gamma-ray spectrum. The gamma-ray spectrum peaks are found at channel numbers corresponding to energies associated with specific nuclear de-excitations characteristic of the chemical element concerned. The relative heights of the peaks are related to the ratios of the elements inside the container. These energies and ratios are in themselves UNIQUELY characteristic of the contents of the container, whether high explosive, nerve gas, or other. In this way, with a
library of known signatures, it is possible to
determine unambiguously the contents of the container.
The extent to which the result is certain is illustrated by a real world example, in which a PINS system was used to confirm the contents of a compressed gas cylinder found buried in the ground.
It can be clearly seen that the spectrum from the container and the spectrum from a cylinder known to contain HF are an excellent match. This
fingerprinting approach is the essence of the method.
Range of Applications
PINS and miniPINS have been demonstrated highly effective in the identification of chemical constituents in a wide variety of containers and forms:
Munitions and Containers
Artillery projectiles: 75 mm to 175 mm
Mortar projectiles: 3-, 4-inch Stokes, 4.2 inch
M-55 rockets, inside S/F tubes and overpacked
Weteye, MC-1, M-70, M-79 bombs, cluster bomblets
Land mines, Livens projectors
Gas cylinders, DOT 500X ton containers
Chemicals
CW agents: CG, CK, HD, HN3, GA, GB, L, VX
Explosives: ANFO, Composition B, RDX, TNT
Gases: acetylene, arsine, chlorine, phosgene, phosphine
Smoke: FM, FS, HC, WP
Practice: sand, water/antifreeze

miniPINS In Operation
The miniPINS software is simple to use. Once the spectrum has been collected and stored, the PINS software analyzes the spectrum to determine the container's contents.
The software employs a logic decision-tree to achieve the identification result.
PINS Deployments
In more than ten years of deployment, PINS systems have been used extensively world wide, often in classified applications, by military and counter-terrorist organizations. Many demonstrations of PINS technology have taken place. Selected user names are available on request.

Supplies
MiniPINS is a portable system. The digiDART Digital Portable Spectrometer operates
from internal batteries for 8 hours. The internal batteries may be recharged from the
line.
The digiDART supplies power to the Ge detector; the latter, although totally portable
in its all attitude 1.2-liter cryostat/dewar, must be refilled with liquid nitrogen every
18 hours. The lifetime of the notebook computer without battery swap or recharge
depends on the model chosen.
