Formatted abstract
The literature review discuss about the past projects carried‐out in 1950s to investigate the characteristics of aerothermodynamics heating and the experimental data being analyzed by various methods. In the case of radiation heat transfer, the past results from numerical analysis show a huge uncertainty which is the motivation to conduct this thesis. Besides, studies also been carried‐out on the operation of expansion tube, cavity gauge and radiation heat transfer.

Models of radiation gauge designed in the past were quite successful; however, there are some questions to its accuracy when come to the detection of VUV radiation in which this small wavelength radiation tends to be absorbed easily by air molecules or window glass. Therefore, studies and computational simulation was done in this thesis to find another way to redesign a radiation gauge that could minimize the highly energize stagnated gas from entering into the cavity while maximize the transmission of DUV/VUV radiation to be measured. Otherwise, the gas flow entering into the cavity would eventually build up undesirable pressure or density that will interrupt the transmission of DUV/VUV radiation (20nm‐200nm).
