AbstractAbstract
[en] The injection archiver system is developed for the SuperKEKB collider. It records the information related to beam injection, pulse-by-pulse, so that the detailed studies of injection conditions become possible. The system is successfully operated during the phase-2 operation of SuperKEKB. The fluctuation and significant loss of injected current are observed with its new determination method. Besides, the recorded data can be utilized for studying the beam backgrounds related to the injection. (paper)

AbstractAbstract
[en] Blood and urinary excretion time courses of 18F administered parenterally to rats were monitored for two hours. The intraperitoneal, subcutaneous, and intravenous routes gave kinetically indistinguishable results after ten minutes following the dose. The blood time course during the first hour following intramuscular dosing showed a relative constancy and suggested a delayed absorption time

AbstractAbstract
[en] Preliminary experiments are described that utilize some of the unique properties of intense electron beams to help achieve the necessary conditions of high energy and power density. The experiments are divided into two groups, dealing with the study of beam dynamics and with plasma heating. (MOW)

AbstractAbstract
[en] The first pellet injection experiments on NBI-heated current-free plasmas in Heliotron E have been carried out. The pellet and plasma species are hydrogen. The increment of line-averaged density is up to 8.2x1019m-3, which is consistent with particle numbers of 1020 contained in a pellet used in the experiment. The behaviour of the plasma is studied in two cases of magnetic field strength, B=1.9 T and B=0.94 T. The density after pellet injection decays slowly (50-150 ms) in most cases, but in some cases with B=0.94 T it decays rapidly (<10 ms). This may be related to power balance. (author)

AbstractAbstract
[en] The aim of the present paper is to introduce the Swedish French Project and to explain its philosophy and expectations. We compare it to other injectors of the same family and underline the conceptual differences. Let us recall that the D- ions are obtained through the following reactions: [D2+ or D+ or D0] + [Cs or Na] → D-. The best rates are achieved with Cesium (approximately 30%) and incident ions of < 1 keV, but it is difficult to create convenient beams at such low energies. Therefore, sodium cells exhibing less efficiency (approximately 18%) are also utilized, because these rates are achieved with incident particle beams of 10 - 20 keV

AbstractAbstract
[en] The DITE Phase II neutral injection system utilises a novel high efficiency plasma source to illuminate a three electrode extraction system operating at 30 kV. The plasma source is a natural development from the multi-dipole permanent magnet confinement system used for basic plasma physics studies and in the Oak Ridge large duopigatron. The design is mechanically simple, gives high electrical efficiency and good uniformity of plasma density across the extraction system. Both Phase II beam lines have two ion sources, each with an extraction area of 8x36 cms and delivering approximately > 300 kW of neutrals to the DITE plasma. Details are given of source efficiency, beam divergence and beam line design

AbstractAbstract
[en] The main components of a cluster injection line intended for plasma heating is briefly discussed, that is the beam source, the cluster ionizer and the accelerating tube, as well as the behavior of clusters interacting with a plasma. Outlines of the experiment of cluster injection into TFR, in progress at Fontenay-aux-Roses, and expected results will be presented and discussed all along the paper

AbstractAbstract
[en] A device and method for relativistic electron beam heating of a high density plasma in a small localized region. A relativistic electron beam generator produces a high voltage electron beam which propagates along a vacuum drift tube and is modulated to initiate electron bunching within the beam. The beam is then directed through a low density gas chamber which provides isolation between the vacuum modulator and the relativistic electron beam target. The relativistic beam is then applied to a high density target plasma which typically comprises dt, dd, hydrogen boron or similar thermonuclear gas at a density of 1017 to 1020 electrons per cubic centimeter. The target plasma is ionized prior to application of the electron beam by means of a laser or other preionization source. Utilizing a relativistic electron beam with an individual particle energy exceeding 3 mev, classical scattering by relativistic electrons passing through isolation foils is negligible. As a result, relativistic streaming instabilities are initiated within the high density target plasma causing the relativistic electron beam to efficiently deposit its energy into a small localized region within the high density plasma target
