THE SPACECRAFT PROPULSION RESEARCH FACILITY (B-2) LOCATED AT GLENN RESEARCH CENTER, PLUM BROOK STATION IN SANDUSKY, OH WAS CONSTRUCTED IN THE MID-1960S TO CONDUCT TESTING OF SPACE PROPULSION SYSTEMS AND OTHER TESTING INVOLVING EXPOSURE TO SIMULATED SPACE CONDITIONS. DURING CONDUCT OF TESTING, IT IS POSSIBLE THAT FUEL, OXIDIZER, TOXIC OR OTHER GASES COULD UNINTENTIONALLY BE PRESENT IN THE FACILITY VACUUM CHAMBER. FOR SAFE OPERATION, IT IS THEREFORE NECESSARY TO DETERMINE THE GAS SPECIES PRESENT. A RESIDUAL GAS ANALYZER (RGA) SYSTEM HAS EXISTED IN THE FACILITY FOR THIS PURPOSE. THE CURRENT ANALYZER HAS BEEN DEEMED OBSOLETE AND AS PART OF THE CURRENT FACILITY REFURBISHMENT PROJECT, IT IS REQUIRED TO HAVE A NEW RGA SYSTEM DESIGNED, BUILT AND INSTALLED AT B-2. THE NEW RGA SYSTEM DESIGN MUST BE COMPLETE BY 30 OCTOBER 2010.
