Remote Non-contact High-Temperature Measurement

SBIR第一阶段的目标是支持一种非侵入性方法的开发，该方法可以精确地检测600至1200摄氏度范围内的表面温度，这是支持“专家”金属有机化学气相沉积系统开发的迫切需要。本文将研究一种基于对埋藏在受热表面的痕量放射性核素的随温度变化的伽马射线通量进行远程探测的无线系统。所提出的方法将在被监测的地点诱发微量的近地表伽马活动，然后遥感由于蒸发而导致的光子通量的减少。多点测量产生的温度均匀性应该是可行的。

The objective of this SBIR Phase I award is to support the development of a non-invasive method of precisely sensing surface temperature in the range 600 to 1200 degrees Centigrade acutely needed to support development of "expert" Metalorganic chemical vapor deposition systems. A wireless system based upon remote detection of the temperature dependent gamma ray flux from trace radionuclides buried in the heated surface will be studied. The proposed approach will induce minute quantities of near-surface gamma activity at the site to be monitored, then remotely sense decreases in photon flux due to evaporation. Multi-point measurements yielding temperature uniformity should be feasible.
