| The Multi-Spectral Solar Telescope Array (MSSTA) is a comprehensive solar rocket-borne observatory which utilizes multilayer coated optics to achieve high resolution thermally resolved images of the sun at FUV, EUV and soft X-ray wavelengths. The MSSTA was successfully flown on May 13th, 1991, obtaining high resolution images of chromospheric and coronal structures, including loops, filaments, polar plumes, and bright points. These images were obtained in six emission bandpasses (C IV {dollar}lambdasim{dollar} 1550A, H Lyman-{dollar}alpha{dollar} {dollar}lambdasim{dollar} 1216A, Fe XIV {dollar}lambdasim{dollar} 211A, Fe XII/XIII {dollar}lambdasim{dollar} 193A, Fe IX/X {dollar}lambdasim{dollar} 173A and Si XII {dollar}lambdasim{dollar} 44.1A) and represent a unique combination of high spatial resolution and spectral differentiation. Four chapters are contained in this thesis. Chapter one reviews the scientific objectives, configuration, and initial flight results from the 1991 MSSTA launch. Chapter two discusses the pre-flight and post-flight calibration of the MSSTA instruments. Chapter three uses the May 13th, 1991 image data to present an analysis of polar plumes and their possible role in the generation of the solar wind. The final chapter details a complete re-design of the payload control electronics undertaken to significantly enhance the capabilities and reliability of the MSSTA for future flights. |
