Spectrometer faciliates remote measurement of ion temperatures and plasma flow

High-resolution visible spectroscopy with McPherson 1-m-focal-length Model 2061 (or 1.33 m Model 209) facilitates remote and spatially distributed, fiber-optic coupled measurement of ion temperatures and plasma flow, even in hostile environments. High magnetic fields do not greatly affect the stable McPherson cast aluminum housings.

High magnetic fields do not greatly affect the stable McPherson cast aluminum housings. The 1m instrument achieves spectral resolution better than 0.02 nm full-width-half-maximum with 10-µm-wide slits. Equipped for imaging, the McPherson high-resolution spectrometer can simultaneously monitor up to 100 input fibers, each with 200 µm core, on 400 µm vertical center-to-center spacing. All on commercial 1024*1024 pixels, ~13mm square CCDs. The systems allow scientists to "peep" at fusion and other plasma experiments, in a noninvasive manner, to monitor select spectral emission lines, like 529 nm carbon, to better understand the plasma formation, temperature, boundary layer interaction and more.

Peeping at Plasmas

High-resolution visible spectroscopy with McPherson one meter focal length Model 2061 (or 1.33m Model 209) facilitates remote and spatially distributed, fiber-optic coupled measurement of ion temperatures and plasma flow, even in hostile environments. High magnetic fields do not greatly affect the stable McPherson cast Aluminum housings.

The 1m instrument achieves spectral resolution better than 0.02nm full-width-half-maximum with 10µm wide slits. Equipped for imaging, the McPherson high resolution spectrometer can simultaneously monitor up to 100input fibers, each with 200µm core, on 400µm vertical center-to-center spacing. All on commercial 1024*1024 pixels, ~13mm square CCDs.

Multi chord spectroscopy benefits from McPherson accessories like multiple entrance slit adapters. We use several parallel entrance slits to multiplex light input when doing narrow-range, high resolution systems. McPherson multiple entrance slit accessories are adjustable in width (e.g. 25, 50, and 100µm) to adjust for resolution and light intensity. They are also adjustable with respect to image rotation and fiber matching. Put a filter in the optical path, add a multiple fiber assembly, and monitor many, many remote and spatially distinct spectral events simultaneously.

The McPherson systems allow scientists to "peep" at fusion and other plasma experiments, in a non-invasive manner, to monitor select spectral emission lines, like 529nm Carbon, in order to better understand the plasma formation, temperature, boundary layer interaction and more.
