This book was released on 2018-08-16 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contract baseline, contract requirements review, contract modifications, contract problem areas and conclusions are addressed. Contract baseline was established 11 June 1987 and updated 1 December 1989. Significant changes were introduced into the 1989 baseline as compared to the original baseline. Contract modifications were made to add requirements as the program matured and as definition of requirements were completed. Problems were solved in real time through the contractor/customer team involvement and relationship to assure a timely and successful mission. The conclusion is that the CGF performed as designed and the experiments performed during the USML-1 Mission supports the conclusion.

This book was released on 2018-08-16 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Crystal Growth Furnace (CGF) is currently undergoing modifications and refurbishment and is currently undergoing modifications and refurbishment and is manifested to refly on the Second United States Microgravity Laboratory (USML-2) mission scheduled for launch in September 1995. The CGF was developed for the National Aeronautics and Space Administration (NASA) under the Microgravity Science and Applications Division (MSAD) programs at NASA Headquarters. The refurbishment and reflight program is being managed by the Marshall Space Flight Center (MSFC) in Huntsville, Alabama. Funding and program support for the CGF project is provided to MSFC by the office of Life and Microgravity Sciences and Applications at NASA Headquarters. This paper presents an overview of the CGF system configuration for the USML-2 mission, and provides a brief description of the planned on-orbit experiment operation.

Available in PDF, EPUB and Kindle. Book excerpt: The concepts of thermal-imaging as applied to the growth of single crystals are presented. A brief history of thermal-imaging is covered with special emphasis on the work done at AFCRL. The design and construction of a vertical furnace embodying these principles is covered together with its use for the growth of a number of single crystals. The furnace represents an advance in the techniques of growth of single crystals of many materials with Air Force applications, including laser hosts, substrate materials, and permanent magnet alloys. It makes possible the growth of these materials without contamination from crucibles and in optimum atmospheres. (Author).

Download or read book Optical Furnaces for Crystal Growth written by Gerhard Kloos and published by Materials Research Forum LLC. This book was released on 2017-03-15 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Well-defined single crystals of high quality are of importance in some branches of industry as well as in fundamental investigations of materials research. This monograph is devoted to the growth of crystals using optical furnaces. Optical furnaces can be understood and designed making recurrence to concepts that stem from analytical geometry. Therefore, these ideas are presented taking both “faces” of analytical geometry into account. For the operation and maintenance of optical furnaces it is advantageous to gain an understanding of their principle of operation and alignment sensitivities. The method of analysis presented in this book strongly relies on pictorial representations and ray tracing is used as a means to visualize the working principles of these furnaces.
