Available in PDF, EPUB and Kindle. Book excerpt: We report results of the TFTR fission detector calibration performed in December 1988. A NBS-traceable, remotely controlled 252Cf neutron source was moved toroidally through the TFTR vacuum vessel. Detection efficiencies for two 235U detectors were measured for 930 locations of the neutron point source in toroidal scans at 16 different major radii and vertical heights. These scans effectively simulated the volume-distributed plasma neutron source, and the volume-integrated detection efficiency was found to be insensitive to plasma position. The Campbell mode is useful due to its large overlap with the count rate mode and large dynamic range. The resulting absolute plasma neutron source calibration has an uncertainty of {plus minus} 13%. 21 refs., 23 figs., 4 tabs.

This book was released on 1989 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutron transport simulations have been carried out to calculate the absolute detection efficiency of a moderated 235U neutron detector which is used on the TFTR as a part of the primary fission detector diagnostic system for measuring fusion power yields. Transport simulations provide a means by which the effects of variations in various shielding and geometrical parameters can be explored. These effects are difficult to study in calibration experiments. The calculational model, benchmarked against measurements, can be used to complement future detector calibrations, when the high level of radioactivity resulting from machine operation may severely restrict access to the tokamak. We present a coupled forward-adjoint algorithm, employing both the deterministic and Monte Carlo sampling methods, to model the neutron transport in the complex tokamak and detector geometries. Sensitivities of the detector response to the major and minor radii, and angular anisotropy of the neutron emission are discussed. A semi-empirical model based on matching the calculational results with a small set of experiments produces good agreement (+-15%) for a wide range of source energies and geometries. 20 refs., 6 figs., 4 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: Tokamak Fusion Test Reactor (TFTR) final operations and post-shutdown neutron activation measurements were made. Ionization chambers were used to follow TFTR activation during operations and after shutdown. Gamma-ray energy spectroscopy measurements were performed to characterize TFTR activation at accessible vessel-bays and on sample hardware removed from structures at various distances from the vessel. The results demonstrate long-lived activations from common, commercially available materials used in the fabrication and field engineering of TFTR. The measurements allow characterization of residual TFTR neutron activation, the projection of residual activation decay, and benchmarking of low activation issues simulations.

Available in PDF, EPUB and Kindle. Book excerpt: One and two-dimensional neutronic analyses treating the transport and scattering of neutrons and the production and transport of gamma rays in the TFTR demonstrate that the fusion energy production in a D-T pulse in the TFTR can be determined with an uncertainty of +- 15% or less, simply by integrating the measured profile of temperature increase along the central radial axis of a large hydrocarbon moderator that fills the bay between adjacent toroidal-field coils, just outside the vacuum vessel. Limitations in thermopile temperature measurements dictate a minimum fusion-neutron fluence at the vacuum vessel of the order of 1012 n/cm2 per pulse (a source strength of 1018 n/pulse in TFTR), in order that this simple calorimeter can provide useful accuracy.

Download or read book Hypnosis in Clinical Practice written by Rick Voit and published by Routledge. This book was released on 2013-02-01 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is aimed at helping both newly trained and experienced mental health professionals become comfortable and adept in using hypnosis in their clinical practice. Despite dramatic evidence of the effectiveness of hypnosis and its growing acceptance, only a small percentage of psychotherapists employ their hypnotherapy training in their practices. This under-use of hypnosis is due to exaggerated misconceptions about its power and the resultant performance anxiety therapists experience after their training. This text is designed to address therapist performance anxiety surrounding the use of hypnosis by exploring the myths surrounding its power and therapeutic potential. The integration of a straightforward systematic hypnotic approach into therapeutic practice has value both in assessment and treatment. Using clinical anecdotes and personal experience, the authors of Hypnosis in Clinical Practice explain induction style and trance work in a way that is fundamental and highly accessible.

Book excerpt: And here is where I fall. Mina Daaé dreams of performing on Broadway. Like her great ancestor, Christine Daaé, who sang at the prestigious Palais Garnier a hundred years before, Mina has the voice of an angel. But after graduating from Conservatoire de Paris, fortune fails her. Until the circus comes to town. Mina’s close friend Toni Vollini offers her a role in his new Broadway play mixing Mozart with clowns. Known as The Harlequin, the musical is an inimitable adaptation of the opera Don Giovanni. Toni says Mina will soar, but with pathologic acrophobia, she’s afraid she’ll fall. And the ghost in her head says she will. Toni and a ghost vie for her love, but Mina thinks her ghost is just another hallucination. Or is her ghost a phantom of the opera? Phantom Masquerade is a contemporary adaptation of Gaston Leroux’s Phantom of the Opera integrating romance and the paranormal.
