Summary
The goals of the Year 2006 Continuation Phase 2 three months period (April 1 to Sept. 30) of this project were to (a) conduct a probe elements industrial environment feasibility study and (b) fabricate embedded optical phase or microstructured SiC chips for individual gas species sensing. Specifically, SiC chips for temperature and pressure probe industrial applications were batch fabricated. Next, these chips were subject to a quality test for use in the probe sensor. A batch of the best chips for probe design were selected and subject to further tests that included sensor performance based on corrosive chemical exposure, power plant soot exposure, light polarization variations, and extreme temperature soaking. Experimental data were investigated in detail to analyze these mentioned industrial parameters relevant to a power plant. Probe design was provided to overcome mechanical vibrations. All these goals have been achieved and are described in detail in the report. The other main focus of the reported work is to modify the SiC chip by fabricating an embedded optical phase or microstructures within the chip to enable gas species sensing under high temperature and pressure. This has been done in the Kar UCF Lab. using a laser-based system whose design and operation is explained. Experimental data from the embedded optical phase-based chip for changing temperatures is provided and shown to be isolated from gas pressure and species. These design and experimentation results are summarized to give positive conclusions on the proposed high temperature high pressure gas species detection optical sensor technology.
