High speed time resolved spectroscopy of plasmas is limited to relatively short record lengths and is very expensive. Advancements in fiber-coupled silicon photomultiplier detectors and ubiquitous low cost computing electronics provide deep record-length, high-speed spectral imaging solutions which are poorly explored. HyperV Technologies Corp. proposes to construct a 16 pixel fiber-coupled, low-light camera head for time resolved spectroscopy of fast plasma events as a proof-of-concept towards an eventual goal of constructing a spectroscopic camera head capable of recording the behavior of 2-4 spectral lines at multiple diagnostic sites with frame rates of 10 MHz or better, and a record length of at least 256,000 frames. This will allow tens to hundreds of milliseconds of time resolved spectra of plasma events to be recorded in a single shot. The primary commercial application is in sales or rental of the device to researchers performing spectroscopy on experiments in which long record length at high time resolution is needed. This includes magnetic fusion devices such as tokamaks, as well as plasma propulsion, and basic plasma physics research. However other low-shot-count, fast emission events could be recorded as well, such as in applications like research in explosives and combustion.
