Inexpensive and practical sealed drift-tube neutron detector

Development of a Permanent-magnet Microwave Ion Source for a Sealed-tube Neutron Generator

A microwave ion source has been designed and constructed for use with a sealed-tube, high-yield neutron generator. When operated with a tritium-deuterium gas mixture the generator will be capable of producing 5 · 10 n/s in non-proliferation applications. Microwave ion sources are well suited for such a device because they can produce high extracted beam currents with a high atomic fraction at l...

Simulation of a Neutron Detector for Real Time Imaging Applications

Monte Carlo Method is used to simulate a double layer gadolinium-amorphous silicon thermal neutron detector. The detector fabricated in pixel array configuration has various applications including neutron imaging. According to the simulation results, a detector consisting of a gadolinium (Gd) film with thickness of 2-4 ~m, sandwiched properly with two layers of sufficiently thick (-30 ?µm) hydr...

Practical, Inexpensive, Nanosecond Time-accuracy Using Gps

This paper investigates a method for achieving timing accuracy of approximately 3ns using low-cost, low-power components suitable for use in embedded systems. After developing an error model and a prototype costing $440 and consisting of an Oncore M12+ GPS receiver, an uncompensated 33MHz oscillator, and an Altera Cyclone Programmable Logic Device, testing indicated shortterm frequency stabilit...
