Scientific application of the Santa Barbara instrument group self-guided spectrograph

Welsh, Frederick V. January 2004 (has links)
The Santa Barbara Instrument Group self-guided spectrograph is aimed primarily at the advanced amateur astronomer. This study has determined that this instrument is capable of being used for scientific research. A comparison lamp box was built to be used in conjunction with the spectrograph. A test was conducted to determine the accuracy of the grating positioning micrometer. A chart was created to allow the conversion of the micrometer readings to correlate with the position of the low-dispersion grating. To determine the scientific applicability of the spectrograph, it was used to: (1) measure the expansion rate of Nova Sagittarius 2004, (2) look for a 13.9-minute periodicity in the width and position of the H-alpha line of the binary star system X Persei, and (3) to measure the Doppler shift of X Persei. The instrument proved to be capable of being used to determine radial velocities and Doppler shifts. / Department of Physics and Astronomy

Design and construction of a high-dispersion infra-red spectrograph

Brealey, George Albert January 1951 (has links)
Details are given of the design and construction of a single-beam, three-prism, infra-red spectrograph, to be used in the near infra-red region 0.7μ to 2.5μ for the purpose of examining fine structure in molecular bands in this region. The problems encountered and methods of solution are explained. Details are presented of the optical and mechanical design of the instrument. The radiant energy transmitted by the spectrograph falls on a PbS photoconducting cell after being chopped at 900 c.p.s. The resulting signal is amplified in a tuned amplifier and, after rectification, is recorded on a Brown recording potentiometer. Details of detector and amplifier are presented. The method of calibration is explained and the performance of the instrument in practice is assessed by consideration of typical spectra taken with the final assembly. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
