Book excerpt: This volume contains the proceedings of the IX International Conference on Hypernuclear and Strange Particle Physics (HYP 2006). This conference series is devoted to the progress of our knowledge about strangeness flavor in hadron and nuclear physics. Besides the traditional topics such as hadron structure, hypernuclear spectroscopy and weak decay of hypernuclei, a particular focus of this conference was on the properties of strange mesons and their binding in nuclear systems.

Available in PDF, EPUB and Kindle. Book excerpt: The radiation detection field has been rapidly growing in the recent three decades due to the Special Nuclear Materials (SNM) proliferation hazards. Monitoring and detecting SNM with high resolution has been a practical issue. Recently, Neutron Scatter Camera (NSC) addressed this issue by identifying the different SNM with high efficiency. However, the huge size of the detection system beside the poor resolution requires developing an alternative NSC. Two Diamond-based Neutron Scatter Camera (DNSC) systems were investigated. The two-diamond array demonstrated good energy resolution of reconstructing spectrum of multiple neutron sources. Moreover, the spectrum of 239PuBe source was reconstructed experimentally via the two-diamond array NSC. The measured spectrum agreed well with the peak of 3 and 10 MeV. On the other hand, the diamond array, in addition to its capability of spectroscopy, pinpointed several neutron sources. For instance, the simulated system could locate and identify a highly active 252Cf source ( 2.3*1010 n/s) placed 1 meter away within 6 hours.The Chi-Nu measurements started back in 2012 at Los Alamos National Lab to obtain more accurate data of fission neutrons. In this dissertation, a novel Double Time-of-Flight (DToF) detection system was utilized to investigate the capability of reconstructing the prompt fission neutrons spectra that were produced by the fast neutron irradiation of two fissile materials which coated a diamond detector. Unlike the Chi-Nu, DToF simulation measurements used only one type of detector (diamond detectors) for all neutron energy range. The simulation results represented good resolution but more accurate correction factors are needed for the low detection efficiency (≈3%) of the system. Protecting astronauts for future space missions from galactic cosmic rays (GCR) is an issue for NASA. Identifying the light ions that strike through the spaceship craft is the first goal to design a shielding material. To address this issue, a [delta]E/[delta]E detector was explored for the measurement of Minimum Ionizing Particles (MIPs) using the beam-line at the NASA Space Radiation Laboratory (NSRL). The measurements were analyzed by Geant4 simulation, which showed promising results in using a delta]E/[delta]E detector to define interacted isotopes.

This book was released on 2008 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the National Ignition Facility (NIF), 192 laser beams will compress a target containing a mixture of deuterium and tritium (DT) that will release fusion neutrons, photons, and other radiation. Diagnostics are being designed to measure this emitted radiation to infer crucial parameters of an ignition shot. Chemical Vapor Deposited (CVD) diamond is one of the ignition diagnostics that will be used as a neutron time-of-flight detector for measuring primary (14.1 MeV) neutron yield, ion temperature, and plasma areal density. This last quantity is the subject of this study and is inferred from the number of downscattered neutrons arriving late in time, divided by the number of primary neutrons. We determine in this study the accuracy with which this detector can measure areal density, when the limiting factor is detector and electronics saturation. We used laser-produced x-rays to reproduce NIF signals in terms of charge carriers density, time between pulses, and amplitude contrast and found that the effect of the large pulse on the small pulse is at most 8.4%, which is less than the NIF accuracy requirement of ± 10%.

Book excerpt: The authors discuss the dynamics, construction, implementation and benefits of a time-of-flight (TOF) detector with count rates an order of magnitude higher and resolution three to four times better than that obtainable with a surface barrier detector. The propose use of design criteria for a time-of-flight detector is outlined, and the determination of a TOF detector's total relative timing error and how this value determines the mass resolution are illustrated using a graphical analysis. They present simulation and experimental examples employing light ions and discuss advantages and pitfalls of medium-energy heavy ion TOF spectrometry.

Download or read book Development of Silicon Drift Detectors for Strangeness Measurements written by and published by . This book was released on 1995 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detection of multi-strange and charm particles requires precise measurements of the secondary vertices close to the interaction point and the decay products of strange and charm particles. This presents an unprecedented challenge for relativistic heavy ion experiments, where multiplicity reaches thousands of final state particles per collision. Development of affordable technology for realizing high spatial resolution and low mass vertex detectors has become the ultimate goal of many R & D projects in major laboratories. In this paper we present preliminary results on silicon drift detectors fabricated for the first time on p-type silicon substrates. These detectors were designed, fabricated and tested recently at LBL and show very interesting properties which make their use in future experiments very likely.

Download or read book CVD Diamond Detectors for Current Mode Neutron Time of Flight Spectroscopy at OMEGA written by and published by . This book was released on 2001 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a laser fusion diagnostic development program, we have performed pulsed neutron and pulsed laser tests of a CVD diamond detector manufactured from DIAFILM, a commercial grade of CVD diamond. The laser tests were performed at the short pulse UV laser at Bechtel Nevada in Livermore, CA. The pulsed neutrons were provided by DT capsule implosions at the OMEGA laser fusion facility in Rochester, NY. From these tests, we have determined the impulse response to be 250 ps fwhm for an applied E-field of 500 V/mm. Additionally, we have determined the sensitivity to be 2.8 mA/W at 500 V/mm and 4.5 mA/W at 1000 V/mm (2 to 6x times higher than reported values for natural Type IIa diamond). These detector characteristics allow us to conceive of a neutron time-of-flight current mode spectrometer based on CVD diamond. Such an instrument would sit inside the laser fusion target chamber close to TCC, and would record neutron spectra fast enough such that backscattered neutrons and y rays from the target chamber wall would not be a concern. However, the data we have taken show that the Electromagnetic Pulse (EMP) noise could be a limiting factor in performance. Determining the degree to which this noise can be shielded will be an important subject of future tests.
