Book Description
Preliminary measurements of the scattering cross section of tritium for protons and the reaction cross section for T3(p, n)H3 have been made. A method of analysis for hydrogen in tritium samples is described. The neutron yield of the reaction is high and will make it a useful source. The threshold is sharp and can be used as a point on the energy scale of nuclear physics. Angular distributions for scattering and cross sections for the reaction are given.

Book Description
Tritium is a radioactive hydrogen isotope that is of interest for both civil and military applications. Most of tritium is used for the realisation and the maintenance of fission and fusion nuclear weapons while only a minor fraction of tritium is commercially used. Among the non-military uses; medical diagnostic and research in pharmaceutical laboratories are discussed. For research purposes, tritium is also used in fusion power machines and, in particular, the development of processes for tritium recovery in the fusion fuel cycle has been the object of significant technological improvements. This book provides an overview on the processes for the production and treatment of tritium in nuclear fusion machines as well as the aspects of measurement, dose assessment and safety of tritium with a focus on the impact to human health and the environment.

Book Description
Tritium activity has been measured in several Pd-Ni-D2O electrolytic cells, as reported previously. At the present time 13 separate cells have shown tritium at 102 to 106 times the background level of the D2O used in these experiments. The appearance of the activity in the electrolyte and in the gas phase occurs over a period of hours to a few days after remaining at or near the background level during 4--10 weeks of charging in 0.1 M LiOD, D2O solution. The present paper deals with attempts to reproduce the tritium measurements and to establish the source, from either contamination or nuclear reaction. The sudden appearance of tritium activity in the cells requires the tritium to be loaded in a component prior to the beginning of cell operation in a contamination model. Release is assumed to be caused by deterioration of one of the materials used in the 0.1 M LiOD solution. In an extensive set of tests, no contamination has been found in the starting materials or in normal water blanks. Results for neutron and gamma-ray correlations have proved to be negative also. The limit set on the absence of 2.5 MeV neutrons for the t/n ration is 107 from that expected in the d + d reaction, and 103 for 14 MeV neutrons expected from the t + d secondary reaction. Similarly, Coulomb excitation gamma rays expected from the interaction of 3 MeV protons with Pd are found to be absent, which indicates that the d(d, p)t two-body reaction does not occur in the Pd electrode. 9 figs., 2 tabs.

Book Description
This paper describes a method of extracting energy from the fusion events occurring between the collision of a beam of protons with a beam of ions of Boron 11. The two beams are circulating in separated and intersecting storage rings where they collide bead-on in a common long-straight section. Requirements on the luminosity of the low-energy collider are shown. Limitations due to space-charge and intrabeam scattering are described. Very fast electron cooling is needed to compensate these effects.

Book Description
Interactions between an intense laser pulse and cluster targets are investigated using the recent experimental results of the cluster fusion experiments on the Texas Petawatt Laser (TPW). We achieved about 2x107 DD fusion neutrons per shot on the TPW by optimizing the laser and gas jet parameters. A few different types of cluster targets were used on the TPW including deuterium clusters, deuterated methane clusters, deuterium cluster + helium-3 mixture, and deuterated methane cluster + helium-3 mixture. We designed our own neutron detectors and proton detectors for the measurements of the fusion yields. The calibration method of neutron detectors is described in detail. Through the yield measurements of the 2.45 MeV neutrons from the DD fusion reactions and 14.7 MeV protons from the D-3He fusion reactions in the deuterium-helium-3 mixture target, we successfully measured the ion temperature of the fusion plasma at the time of the fusion reactions.
