The measurement of the variation of fluence from a Plasma Radiating Source (PRS) with polar angle is critical to the definition of the stimuli acting on an effects experiment using PRS diagnostics because in general experiments and diagnostics view thesource from different angles. The polar angle fluence distribution is controlled by the opacity of the pinch, which is a sensitive function of pinch conditions. The frequently assumed Lambertian (cosine) radiator conditions results in significant error.Polar angle fluence distribution of a source must be measured for each PRS design. No capability to make these measurements presently exists.It is proposed to develop a fast total stopping intrinsic (FTSI) calorimeter array to measure the polar angle fluence distribution of NWE PRS. FTSI calorimeters are potentially the most accurate and least expensive diagnostic option that can be fieldedwithin the test chamber.The velocity of existing calorimeter designs is questionable at best because of their configuration, slow response and ill defined thermal loss corrections. Accurate estimation of the fluence incident on a calorimeter can be obtained if the calorimeter isdesigned to provide fast response and the configuration allows proven dynamic error compensation. These design techniques were successful in UGT calorimeter design.Polar angle PRS fluence distribution measurements for each PRS are critical to accurate NEW experiments. Development of a FTSI calorimeter will significantly improve the available suite of PRS diagnostics. The FTSI calorimeter design has wide applicationto electron and ion beam, laser and thermal radiation diagnostics. The required thermal analysis techniques can be used to evaluate high rate thermal industrial processes.
