The neutron-activation method was used for obtaining new experimental data on cross sections both for Ge(n,2n)Ge nuclear reaction and for some other (n,x) reactions on zirconium and germanium isotopes. The neutron generator was used as a neutron source. The samples in a shape of foils of natural germanium and zirconium were irradiated by DTneutrons. The following sources of uncertainties are ta...

This article was originally intended as a brief introduction to the article by Richard Hull on the Farnsworth/Hirsch “fusor.” However, as there has been some interest by a number of subscribers in neutron generators, I decided to provide a somewhat more lengthy tutorial on the reactions that produce neutrons, some practical applications of neutrons, and a few of the various types of devices tha...

Pyroelectric crystals have been used to achieve D-D fusion. One goal of research conducted at RPI is to develop a portable neutron generator using pyroelectric crystals as an ionization and acceleration source for deuterium ions. The research reported here includes the use of two pyroelectric crystals to generate neutrons in a portable prototype vacuum system. Experiments were conducted to dete...

Since wireless sensor networks have limited energy resources, energy efficiency and reliable data transmission rate are key issues in designing the topology. In this paper, a new root protocol NCQ-DD is proposed in order to solve the issue of limited performance of DD in wireless sensor networks. NCQ-DD greatly improves traditional DD protocol by utilizing random linear network coding technolog...

The formation and physico-chemical properties of biomaterial, based on double-stranded (ds) DNA molecules and bearing high concentration of gadolinium, is described. This “rigid” biomaterial demonstrate a few unique properties: 1) the ds DNA molecules forming complexes with gadolinium are fixed in the spatial structure of “rigid” particles, 2) an abnormal negative band in the circular dichroism...

The phenomenon of pyroelectric electron emission has been employed to develop miniature x-ray sources, such as the Cool-X by Amptek swww.amptek.com/coolx.htmld. The source strength of a pyroelectric x-ray generator is dependent on the emitted electron energy and current. Similarly, the source strength of a pyroelectric neutron generator will be dependent on the energy and production rate of deu...

In the framework of Thomas-Fermi approximation, we study systematically EOSs and microscopic structures neutron star matter in a vast density range with $n_\mathrm{b}\approx 10^{-10}$-2 $\mathrm{fm}^{-3}$, where various covariant functionals are adopted, i.e., those nonlinear self couplings (NL3, PK1, TM1, GM1, MTVTC) density-dependent (DD-LZ1, DDME-X, PKDD, DD-ME2, DD2, TW99). It is found that...

Background: Several landmine detection methods, based on nuclear techniques, have been suggested during the recent years. Neutron energy moderation, neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are nuclear-based methods used for landmine detection. The aim of this study is to use backscattered neutron for landmine detection. Materials ...
