9612538 Kenny This proposal describes an effort to develop a Micromachined Calorimeter for the NASA/JPL New Millennium Spacecraft Program. This device will be used to study effects of the ion engine exhaust plume on passive infrared radiators used to release heat from the spacecraft core and from science instruments. New Millennium is a technology validation program, and will provide a flight opportunity on the first Deep Space 1 (DS1). The performance of exposure calorimeters is improved through reduction of heat capacity and thermal conductance. Silicon Micromachining is ideally suited to this task, offering low-stress nitride membranes with well-characterized, thermal, mechanical, and optical characteristics. The expected characteristics of the Micromachined Calorimeter offer a significant performance improvement over conventionally-built calorimeters. ***

9612538 Kenny这个提案描述了为NASA/JPL新千年航天器计划开发微机械热量计的努力。 该装置将用于研究离子发动机排气羽流对用于从航天器核心和科学仪器释放热量的被动红外辐射器的影响。 新千年是一项技术验证计划，将为第一个深空1号（DS 1）提供飞行机会。 通过降低热容和热导率来改善曝光量热计的性能。 硅微机械加工非常适合这项任务，提供具有良好特性，热，机械和光学特性的低应力氮化物膜。 微机械量热计的预期特性比传统量热计提供了显着的性能改进。 ***
