Shift Register Neutron Coincidence Module
نویسنده
چکیده
A neutron coincidence module was designed using multistage shift registers to produce the coincidence gates 3nd a crystal controlled oscillator with variable clock outputs to change the gate lengths. The advantage of this system over the conventional, thermal-neutron coincidence gates is a decrease in deadtime by more than an order of magnitude.

New Shift-register Electronics for Improved Precision of Neutron Coincidence and Multiplicity Assays of Plutonium and Uranium Mass
Active and passive neutron-coincidence counting (NCC) is used routinely for nondestructive assay (NDA) of uranium and plutonium, in many forms. Passive neutron multiplicity counting (PNMC) is used routinely for NDA of plutonium scrap and waste. We’ve developed and extensively tested new electronics that significantly improves precision of double and triple coincidences, and multiplicity assays....
متن کاملPrecision of the Accidentals Rate in Neutron Coincidence Counting
The quantification of Pu present, for example, as process hold-up in glove boxes or in waste containers may be accomplished by passive neutron coincidence counting (PNCC) to determine the Pu-240 effective mass which may then be related to the total Pu mass or Pu-239 mass through the isotopic composition. When multiplication can reasonably be taken as slight, assay results are normally based on ...
متن کاملSolving Shift Register Problems over Skew Polynomial Rings using Module Minimisation
For many algebraic codes the main part of decoding can be reduced to a shift register synthesis problem. In this paper we present an approach for solving generalised shift register problems over skew polynomial rings which occur in error and erasure decoding of `-Interleaved Gabidulin codes. The algorithm is based on module minimisation and has time complexity O(`μ) where μ measures the size of...

A Multi-H% Time-to-Amplitude Module (MTAC) for the SI.AC Mark III drift chamber system has been designed to measure drift time by converting time-proportional chamber signals into analog levels, and converting the analog data by slow readout via a semi-autonomous controller in a CAMAC crate. The single width CAMAC module has 16 wire channels, each with a 4-hit capacity. An externally generated ...
متن کاملBit Swapping Linear Feedback Shift Register For Low Power Application Using 130nm Complementary Metal Oxide Semiconductor Technology (TECHNICAL NOTE)
Bit swapping linear feedback shift register (BS-LFSR) is employed in a conventional linear feedback shirt register (LFSR) to reduce its power dissipation and enhance its performance. In this paper, an enhanced BS-LFSR for low power application is proposed. To achieve low power dissipation, the proposed BS-LFSR introduced the stacking technique to reduce leakage current. In addition, three diffe...
