The GaCl3/SiH4/H2 system is of interest for the production of high quality epitaxial gallium doped silicon. A thermodynamic analysis and spectroscopic investigation of this chemical vapor deposition (CVD) chemistry is described over the temperature r

In many experiments that use pulsed laser excitation, it is necessary to gate a photomultiplier tube either on or off to prevent saturation of the detector while recording much weaker events that follow only a few microseconds later. Several methods

Electrical Contacts - 1999. Proceedings of the Forty-Fifth IEEE Holm Conference on Electrical Contacts (Cat. No.99CB36343).
A new concept for a current-limiting fast circuit breaker was investigated to determine design factors that either significantly limited or enhanced performance capability. Positive factors included location of the arcing contacts adjacent to the cor

A visible chemical laser on the BiF(A-X) transistions at 430-470 nm can potentially be generated by the interaction of Bi-atoms with metastable species such as NF(a1Δ). Experiments were performed in which these constituents were obtained in situ by

A spatially resolved optical diagnostic for GaCl is described. The technique uses 248-nm excimer laser radiation to photolyze GaCl and also to excite fluorescence in the resulting gallium atoms. This yields gallium fluorescence at 245, 266, 287, 294,

Small offsets in frequency from a given reference can be generated in a single sideband mixer employing a PLL. It is shown that the output frequency stability depends linearly on the fractional shift of the offset frequency generated, and on the cohe

Alkaline earth catalyzed N2O-CO flames have been studied as potential electronic transition chemical lasers. The addition of CO to the M+N2O flames, where M=Mg, Ca, and Sr, has been shown to efficiently produce the respective metastable alkaline eart

The potential of isocyanic acid as a fuel for a short-wavelength chemical laser has been investigated. The experiments were performed by carrying out reactions of F atoms with HNCO to obtain NCO radicals and with coreagents of the type RHn.to obtain

Quantitative fluorometry of transient combustion species is complicated by the need for information on the composition and quenching rates of the entire system. Saturated fluorometry is one approach to this problem. An alternative, nonsaturating fluo
