The SSC needs a hydrogen temperature sensor that can provide high accuracy, fast response and can be operated on a superheated hydrogen (SHH2) environment. This will help prepare the SSC testing facility to support the new NASA mission for US space exploration as proposed by the President in January 2004. Here, we propose to develop an innovative, non-intrusive temperature sensor based on Spontaneous Raman Scattering (SRS). SRS has been known for years as a relatively simple analytical method. The goal of the proposed effort is to demonstrate a SRS sensor, which is able to provide millisecond sampling time for temperature measurements in SSH2. During Phase I, a SRS system based on a 0.5 spectrometer and ICCD detector will be used to find the best hydrogen bands for the temperature measurement. The fast response PMTube - based SRS system will then be designed for selected spectral lines. Experimental parameters will be evaluated to achieve optimum response time and sensitivity for this application. The study from Phase I will provide the necessary information to design a phase II prototype unit to achieve millisecond response time and better sensitivity in a compact package. In Phase II, the prototype SRS system will be developed and tested at the SSC and will be delivered to NASA/SSC for their evaluation.
