Recently two papers on how to perform passive neutron auto-correlation analysis on time gated histograms formed from pulse train data, generically called time correlation analysis (TCA), have appeared in this journal Dubi et al. Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment (673) (2012) 111; Croft et al. Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment (691) (2012) 152. For those of us working in international nuclear safeguards these treatments are of particular interest because passive neutron multiplicity counting is a widely deployed technique for the quantification of plutonium. The purpose of this letter is to show that the skewness-variance-mean (SVM) approach developed in Dubi et al. (Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment (673) (2012) 111) is equivalent in terms of assay capability to the random trigger interval (RTI) analysis laid out in Croft et al. Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment (691) (2012) 152. Mathematically we could also use other numerical ways to extract the time correlated information from the histogram data including, for example, what we might call the mean, mean square, and mean cube approach. The important feature however, from the perspective of real world applications, is that the correlated information extracted is the same, and subsequently gets interpreted in the same way based on the same underlying physics model.

The present comment concerns the correct presentation of an algorithm proposed in the above paper for the glow-curve deconvolution in the case of continuous distribution of trapping states. Since most researchers would use directly the proposed algorithm as published, they should be notified of its correct formulation during the fitting of TL glow curves of materials with continuous trap distribution using this Equation.

I perform tracking simulations to fit various measurements of the polarization for a stored uncooled polarized deuteron beam, published in the recent paper by Benati et al. [P. Benati et al., Physical Review Special Topics—Accelerators and Beams 15 (2012) 124202]. The collaboration kindly sent me datafiles of the polarization measurements, and also pertinent details of the experimental data acquisition procedure. The latter are essential to obtain quantitative fits to the data. I describe my findings and inferences from the data. In some cases I offer alternative interpretations of the data from that given by Benati et al. [1]. I also correct some mistakes in my recent paper [S.R. Mane, Nuclear Instruments and Methods in Physics Research Section A 726 (2013) 104–112].

With the advent of high-current high-energy proton accelerators used as pulsed neutron sources for condensed matter studies, interest in extending neutron scattering measurements to the eV region has increased. Among the instruments proposed is the resonance-detector spectrometer (RDS) which uses the sharp low-energy nuclear resonances (usually capture) to define the energy of the scattered neutron. These spectrometers require detectors with high efficiency and good background rejection. Two promising candidates for such detectors, a bismuth germanate (BGO) scintillator and a high-purity germanium (HPGe) detector have been tested at the NBS neutron time-of-flight facility. These tests used simple recoil scattering at high scattering angles and several different resonance foils. Efficiencies and signal to background ratios were measured.

One of the main uses for 3He is in gas proportional counters for neutron detection. Such detectors are used at neutron scattering science facilities and in radiation portal monitors deployed for homeland security and non-proliferation applications. Other uses of 3He are for research detectors, commercial instruments, well logging detectors, dilution refrigerators, lung imaging, for targets in nuclear research, and for basic research in condensed matter physics. The supply of 3He comes entirely from the decay of tritium produced for nuclear weapons in the U.S. and Russia. Due to the large increase in use of 3He for science and homeland security (since 2002), the supply could no longer meet the demand. This has led to the development of a number of alternative neutron detection schemes.

The PHENIX experiment at the Relativistic Heavy Ion Collider studies strongly interacting matter in nucleus–nucleus, polarized proton–proton and proton (deuterium)–nucleus collisions. Its prime fields of research are the exploration of hot and dense nuclear matter, studies of the gluon spin composition of the nucleon, and investigations of parton structures in nuclei. The experiment is being upgraded with a silicon vertex detector that will substantially enhance the physics capabilities of its central arm spectrometers. The silicon vertex detector consists of a four-layer barrel, built from two internal layers of pixel detectors and two external layers of projective “strip-pixel” detectors which complement the central electron spectrometer arms of PHENIX.

The predicted reduction in the total background for current balloon-borne instruments is more than a factor of 1.7 between 0.2 and 1.0 MeV. For future satellite instruments, the reduction in this energy range is by more than a factor of 5.

A study is presented of the instrumental background in astrophysical gamma-ray spectrometers using isotopically enriched germanium detectors. Calculations show that the beta-decay background, which is the largest component between ∼ 0.1 and 1.0 MeV in balloon-borne and satellite spectrometers, is dominated by the activation of 74Ge. This component can be reduced by an order of magnitude using detectors enriched to > 80% in 70Ge. The predicted reduction in the total background for current balloon-borne instruments is more than a factor of 1.7 between 0.2 and 1.0 MeV. For future satellite instruments, the reduction in this energy range is by more than a factor of 5.

Nuclear physics experiments to be conducted at future accelerators will result in the accumulation of vast quantities of data. This paper briefly discusses an object-oriented database (OODB) approach for effectively managing this data and, more importantly, presents an object-based conceptual model of a nuclear physics experiments database as an initial by-product of applying this approach. The database model is provided by an object-relationship diagram (ORD). The concepts and conventions related to an ORD are explained, and the ORDs and associated terminology of the proposed model are given. Two prototypes that are currently being developed based on the model are also briefly discussed. The nuclear physics experiments database model and prototypes result from software research and development efforts associated with the Continuous Electron Beam Accelerator Facility (CEBAF).

The pd reaction at ultra-low proton–deuteron collision energies has been studied using the Hall pulsed ion accelerator and the solid target of heavy water D2O. The experiment on measurement of the astrophysical Spd factor and the pd reaction cross-section was carried out at average pd collision energies 8.28, 9.49, and 10.10 keV. The 5.5-MeV γ rays from the pd reaction were detected by detectors based on plastic scintillators and NaI(Tl) crystals. Parameters of the accelerated hydrogen ion flux were measured and monitored with diagnostic equipment consisting of an energy analyzer, plasma optical radiation detectors, the Rogovsky belt, and collimated Faraday cups. The results obtained agree within the errors with the data of the pd experiments carried out by the LUNA collaboration at the Gran Sasso Laboratory with a target filled with gaseous deuterium. The reported experiment was carried out at the Hall ion accelerator of the Research Institute of Nuclear Physics, Tomsk Polytechnic University.

Silicon tracking detectors—historical overview The introduction of planar technology provided a boost to the industrial production and use of silicon strip detectors. Nowadays, all particle physics spectrometers have inbuilt vertex detectors, which deliver excellent results. The application of silicon tracking detectors has expanded to nuclear physics, solid-state physics, astrophysics, biology and medicine.

Semiconductor detectors have been known for more than 50 years, however their tracking capabilities, exhibiting spatial resolution in the 5–10 μm range, began to be explored only in the beginning of the 1980s, when experimental physics began to search for detectors to measure short-living particles. The introduction of planar technology provided a boost to the industrial production and use of silicon strip detectors. The next essential step came with the development of a dedicated VLSI readout, which allowed for integration of detectors and electronics. Efforts towards obtaining two-dimensional detectors were initiated right from the beginning, with CCD devices being the subject of early investigation. A second line of development involved pixel devices with thick sensitive layers—they began to be successfully implemented in experiments towards the end of the 1990s. Radiation effects in detectors and electronics were recognized early, however it took many years to understand the physics of radiation damage—currently, we possess detectors and electronics capable of surviving doses of 10 Mrad and fluxes of 1014 neutrons/cm2, or higher. Nowadays, all particle physics spectrometers have inbuilt vertex detectors, which deliver excellent results. The application of silicon tracking detectors has expanded to nuclear physics, solid-state physics, astrophysics, biology and medicine.
