Published 1990Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: One of the objectives of the TISOL (Test Isotope Separator On Line) facility at TRIUMF is the production of low Z radioactive isotopes, with a special interest in those related to nuclear astrophysics. A part of experimental objectives is the installation of an electron cyclotron resonance ion source on-line to test its suitability for this use. In collaboration with TISOL, the University of Alberta has designed, built, and tested off-line a single stage ECRIS. As part of the source, testing measurements were carried out to determine the efficiency of the source; some preliminary results indicate efficiencies of 20% for Ne+ and 30% for Ar+. In general, it was attempted to test the source under as wide as possible a set of operating conditions. The final off-line testing is completed. It is hoped that the source will go on-line in the early summer of 1989.Type of Medium: Electronic ResourceURL: -

Published 1998Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: An ECR ion source is converted to produce a beryllium fluoride beam, which will be stripped to 7Be+2 beam and used in 7Be(p,γ)8B experiments at ISAC. The source consists of an injection chemical chamber and a plasma chamber. Chemically purified (99.9%) BeO is placed in the chemical chamber which can be heated up to 1000 °C. A CF4 leak connected to that chamber serves as the source of CF4 for the reaction to produce BeF2. The BeF2 is then injected into the hot electron layer region of the plasma chamber to enhance the ionization efficiency. A detailed source description, beam parameters and ionization efficiency measurements are presented in this paper. © 1998 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1998Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: We describe an ultrahigh vacuum instrument for transmission electron microscopy and reflection electron microscopy for the study of surfaces and thin film growth. The focus of previous experiments was on the high spatial resolution (〈3 Å) generally associated with microscopy, at the cost of controlled growth and characterization. We have taken a different approach. It has been shown that most experiments using diffraction and diffraction contrast imaging can be performed well at poorer resolution (∼20 Å), including the imaging of monatomic steps and monolayer coverages. The instrument is designed for best control of growth and vacuum, with sacrifices in optical resolution, which is theoretically ∼2 nm. The instrument is called SHEBA (surface high-energy electron beam apparatus). We can examine a ∼1 cm2 sample in both transmission electron microscopy and reflection electron microscopy, in situ with well-controlled molecular beam epitaxy (MBE) growth capabilities, well characterized vacuum, and surface characterization by Auger spectroscopy and low-energy electron diffraction. Preliminary experiments of cobalt on silicon have shown MBE growth rates ranging from 1.5 monolayers per hour to 18.3 monolayers per hour depending on the temperature of the evaporation source. Using SHEBA for a reactive MBE experiment has provided the first direct evidence of the formation of aluminum nitride by nitridation of basal plane sapphire. The most serious design problems were stray magnetic fields and mechanical vibrations. These have been overcome and allow a spatial resolution of 〈10 nm. The instrument is expected to be very valuable in studies of film growth. © 1998 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1996Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: An on-line emittance–mass scanner (EMS), with a size of 10 cm×10 cm×8 cm, has been developed for use with low energy and light ion beams (A〈40) at TRIUMF. Computerized data acquisition and procession give the rms emittances, intensities, and contour plots of each beam component. The angular resolution of the scanner is ±1.0 mrad, the maximum divergence of each component that the scanner can take is 140 mrad. Some experimental results of the measurement are given. The comparison between the contour shapes and the values of the emittance measured by both the emittance scanner and EMS is in good agreement. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1994Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: Several H−/D− dc sources employing multicusp confinement and magnetic filtering to enhance H−/D− production have been designed, built, and tested. Source performance in terms of beam output, emittance merit as functions of arc current, confinement magnetic strength, plasma volume, beam exit diameter, and extraction lens configuration have been studied in detail. At present, up to 9 mA H− and 3 mA D− beams with a normalized emittance of 0.44 mm mrad for H− beam have been extracted. A number of sources are tailored to fit the requirements of individual projects. In this article, a general description of source structure, power and biasing algorithms, and extraction geometries of these cusp sources will be given.Type of Medium: Electronic ResourceURL:
