4-Instruments for the Extreme Ultraviolet
4-instruments for the extreme ultraviolet Four instrument systems developed specifically for analytical and diagnostic spectral metrology of soft x-ray and ultrafast extreme ultraviolet photon sources and laser systems. These spectrometer instruments can make optical measurements from 0.5 to more than 500 nanometers. Working in the UV? McPherson has it covered. McPherson makes spectrometers proven to work at the shortest optical wavelengths. From wavelengths less than one nanometer, up to the visible light range, our analytical and diagnostic instruments fit to your application. They work in high harmonic generation (HHG) laser diagnostics. They work in advanced semiconductor extreme UV metrology and analytics. They work in high temperature soft x-ray plasma physics diagnostics. All are available for ultra high (UHV) or high-vacuum applications. McPherson manufactures numerous spectrometer models and optical designs. Here are those with staying power popular across many spectroscopy disciplines. 1. For measuring low energy deep-UV wavelengths (50-500nm) there is the Model 234/302. It’s a great instrument to transition from ultraviolet to wavelengths as short as 30 nanometers. Works equally well in scanning applications as with direct detection CCD for rapid collection of diagnostic spectra. If you need finer spectral resolution, consider Model 235 or Model 225 for the same wavelength range. 2. Do you need analysis and diagnostics with high energy spectra (1-300nm)? Then the vacuum ultraviolet (VUV) Model 248/310 fits the bill. It works with point detectors or as a scanning monochromator using concave spherical gratings. The slit or detectors scan along the Rowland circle. It works with direct- detection CCD, MCP intensifier, and when integrated with a spectral lamp, makes a tunable light source. -
Thomas Pütterich Investigations on Spectroscopic Diagnostic
Thomas Pütterich Investigations on Spectroscopic Diagnostic of High-Z Elements in Fusion Plasmas IPP 10/29 April 2006 Abstract Nuclear fusion of deuterium and tritium relies on the accomplishment of plasma temperatures in the range of 20 keV. In magnetic confinement fusion, the heat transport and radiation losses are compensated by plasma heating. This scheme relies on the control of the loss mechanisms and in particular the plasma radiation. Tungsten (W) is the main candidate for the first wall of a reactor due to its robustness against physical sputtering by the plasma ions, however, 4 when W reaches concentrations of 10− in the plasma, it causes unduly large plasma cooling by radiation. This implies restrictive impurity control for W, which needs reliable diagnostic by plasma spectroscopy. A pre-requisite for interpretation of the W-spectra is the availability of atomic data for W. The most intense spectral lines of highly ionized W are emitted in the VUV and soft X-ray range. To perform calculations on atomic data the code packages incorporated in the ADAS project are used. The electronic structure of nearly all W-ions is calculated by the Cowan-code (Hartree-Fock algorithm). In a second step, the cross sections for electron impact excitation are evaluated via the Cowan-code using the plane wave Born-approximation. A detailed collisional-radiative model is employed to calculate the model-spectra for each ion in equilibrium. Finally, ionization and recombination rates of W are evaluated by semi-empirical formulae, which make use of the electronic structure calculations of the Cowan-code. -

Planetary Science Institute Spectroscopy Lab Annual Report for 2017 Prepared by Neil Pearson
Planetary Science Institute Spectroscopy Lab Annual Report for 2017 prepared by Neil Pearson Summary In October of 2017 Neil Pearson was hired as the Lab Technician for the Planetary Science Institute (PSI), with the primary purpose to run and upkeep equipment that was purchased by PSI and its associated scientists. This report will cover activities between October, November and December of 2017. The spectroscopy lab currently has three main instruments in house and a fourth that is with Dr. Eldar Noe Dobrea at NASA Ames. The three instruments currently at PSI are the Andor-McPherson Vacuum Ultraviolet (VUV) Spectrometer, the Ocean Optics Ultraviolet to Visible spectrometer, and the Analytical Spectral Devices (ASD) Fieldspec 3 visible to short wave infrared spectrometer. Dr. Eldar Noe Dobrea has in his possession an Olympus Terra X-ray diffractomeer and X-ray fluoresence spectrometer. Additionaly, the lab contains and high vacuum chamber for measuring samples in space like conditions. Efforts since October have focused on tuning and calibrating instruments, and preparing the laboratory for measuring samples for the Toolbox for Research and Exploration project headed by PSI’s Dr. Amanda Hendrix, and investigating reflectance standards for the vacuum-UV Currently two abstracts were submitted to the 2018 Lunar and Planetary Science Conference that will use spectra taken at the PSI spectroscopy lab. Laboratory Instruments The Andor-McPherson VUV spectrometer is the most unique instrument at the PSI spectroscopy lab. This instrument combines a Andor Solis cooled silicon detector array with a McPherson Inc. Monochrometer and 300 line/mm grating. The VUV spectrometer measures reflectance of minerals samples in the VUV down to ~0.115μm and in its normal operating mode goes to 0.4μm with a spectral resolution of 8nm.
