Far Ultraviolot Space Telescope (FAUST)

The Far Ultraviolet Space Telescope is a compact, wide field-of-view, far ultraviolet instrument designed for observations of extended and point sources of astronomical interest. It was originally used in sounding rocket work by both French and American investigators. The instrument was modified for flight on the space shuttle and flew on the Spacelab 1 mission as a joint effort between the Laboratoire d'Astronomie Spatiale and the University of California, Berkeley. The prime experiment objective of this telescope on the Atmospheric Laboratory Applications and Science (ATLAS 1) NASA mission is to observe faint astronomical sources in the far ultraviolet with sensitivities far higher than previously available. The experiment will cover the 1300 to 1800 A band, which is inaccessible to observers on earth. The observing program during the mission consists of obtaining deep sky images during spacecraft nighttime. The targets will include hot stars and nebulae in our own galaxy, faint diffuse galactic features similar to the cirrus clouds seen by the Infrared Astronomical Satellite (IRAS), large nearby galaxies, nearby clusters of galaxies, and objects of cosmological interest such as quasars and the diffuse far ultraviolet background

Fabrication and evaluation of large-area ultrasoft X-ray detectors suitable for spacecraft application

The modifications to the Houston/MSC design of the gas proportional counter flight electronics system are discussed. The following modifications are described: charge amplifier bandwidth improvements, power converter redesign, serial data output buffer, second differentiator, and risetime discriminator. In addition, the redesign of the stellar aspect camera is discussed along with developments in thin film fabrication

Research in extreme ultraviolet and far ultraviolet astronomy

The Far Ultraviolet imager (FUVI) was flown on the Aries class sounding rocket 24.015, producing outstanding results. The diffuse extreme ultraviolet (EUV) background spectrometer which is under construction is described. It will be launched on the Black Brant sounding rocket flight number 27.086. Ongoing design studies of a high resolution spectrometer are discussed. This instrument incorporates a one meter normal incidence mirror and will be suitable for an advanced Spartan mission

A study of the atmosphere and ionosphere using satellite observations of 300-1400 Ang airglow

A study of the O(+) ion distribution reveals that the OII 834 A emission can be used to infer the O(+) density as a function of altitude. The ion temperature was obtained from these measurements. Variations of the ion density distributions were obtained as a function of latitude. Daytime observations show that the OII 834 A emissions contain the signature of the Appleton anomary. Analysis of the 300 to 900 A auroral spectra reveals a large number of OII features. Several pairs of OII features with a common upper state were used to obtain their branching ratios and compared with laboratory observations and theoretical calculations. Evidence for OIII emissions were also found in an aurora

Research in extreme ultraviolet and far ultraviolet astronomy

Analysis and interpretation continued on data generated by the flight of 27.086 in April of 1986 and by the successful UVX mission. Optical and mechanical design of the 1 meter EUV telescope, planned for launch with the large SPARTAN type carrier, ASTRO-SPAS, was also continued. The major effort centered on the preparation of flight 27.106, scheduled to launch in September, 1986. Work which was performed included: design of the skins and bulkheads; completion of the optical, mechanical, and electrical design; purchase of the major components of the instruments; assemblage of the electrical components; and performance of theoretical work, to support the data interpretation

Apollo-Soyuz test project Extreme Ultraviolet Telescope MA-083

Follow-on studies to the Apollo-Soyuz Extreme Ultraviolet Telescope experiment (MA-083) include analyses of individual target stars or classes of stars, not only with regard to the EUV data but also in connection with theoretical models and observations in other parts of the spectrum. Topics discussed include: observations of SS Cygni, Proxima Centauri, HZ 43, and Feige 24; computer searches for new EUV sources; Sirius: models and inferences; EUV emission from a hot gas; and the diffuse EUV background

High-intensity source of extreme ultraviolet

High intensity ultraviolet radiation source was developed which is suitable for emission below 500 A. Source, useful for 100 to 1000 A range, is simple and inexpensive to construct, easy to operate, and very stable. Because of sufficiently intense output spectrum, source can be used with monochromator at wavelengths as low as 160 A

Study of X-ray emission from selected regions of the Southern Hemisphere sky Summary report

Acquisition and processing of X ray data from Southern Hemisphere sk

FUSE/Lyman grant

A variety of options for a short wavelength spectrometer for the Lyman telescope has been studied, and the optimum configuration for this instrument identified. In this spectrometer option study it is assumed (consistent with performance goals outlined by the project) that the instrument, whose prime spectral domain is 900-12000A, will incorporate a grazing incidence telescope which will maintain good collecting efficiency down to 100A. In particular it is assumed that the telescope will have an effective focal length of 10 meters, an image quality of 1.5", and will provide a diverging f/10 beam. Designs compatible with this telescope are analyzed, and it is determined that a two-element grazing incidence spectrometer using as its first optic an ellipsoid to re-focus the beam and a varied line-space plane diffraction grating to disperse the light is the best overall design. This spectrometer could be fed by a small pick-off mirror located just behind the prime focus of the telescope and would clear the light path when not in use. A test of the diffraction efficiency of a low blaze angle grating is undertaken, which is the only technical uncertainty in the spectrometer design

Leeds Free School Meals Research Project (Phase 2 Report: Findings from the pilot phase Leeds Metropolitan University)

Free school meals aim to provide a “nutritional safety net” for the poorest UK children. Yet it is estimated that up to 30% of those entitled do not take up this entitlement. In Leeds approximately 6,000 children do not take the free school meals that they are entitled to. National and local targets are for 100% take up. Phase 2 of the Leeds Free School Meal Research Project aimed to develop, implement and evaluate a series of interventions to increase the uptake of free school meals. The interventions were tested in ten Leeds schools between December 2007 and October 2008. The research was undertaken by the Department of Nutrition & Dietetics within The Centre of Food Nutrition and Health at Leeds Metropolitan University on behalf of Education Leeds
