Absolute intensity calibration of the Wendelstein 7-X high efficiency extreme ultraviolet overview spectrometer system.
The new high effiency extreme ultraviolet overview spectrometer (HEXOS) system for the stellarator Wendelstein 7-X is now mounted for testing and adjustment at the tokamak experiment for technology oriented research (TEXTOR). One part of the testing phase was the intensity calibration of the two double spectrometers which in total cover a spectral range from 2.5 to 160.0 nm with overlap. This w...
متن کاملAn Extreme Ultraviolet Spectrometer
A concept and preliminary design of an Extreme Ultraviolet (EUV) spectrometer is presented. The spectrometer is based on a gas ionization chamber and an advanced eight-electrode electron focusing system to form a narrow electron beam on a photodiode aperture. The design is modeled with the SIMulation of IONs (SIMION) tools and shows the ability to scan through the spectral range of 20.0 – 40.6 ...
متن کاملDesign, fabrication, and characterization of high-efficiency extreme-ultraviolet diffusers.
As the development of extreme-ultraviolet (EUV) lithography progresses, interest grows in the extension of traditional optical components to the EUV regime. Because of the strong absorption of EUV by most materials and because of its extremely short wavelength, however, it is difficult to implement many components that are commonplace in the longer-wavelength regimes. One such example is the di...
متن کاملAn Extreme Ultraviolet Optics-Free Spectrometer With Improved Spectral Resolution and High Signal-to-Noise Ratio
A computer model of an Extreme Ultraviolet (EUV) spectrometer based on a gas ionization chamber and on flight experience of the Optics Free Spectrometer (OFS previously flown), was built and tested with the SIMulation of IONs (SIMION) tools. Our goal in this work was to design an improved and simplified electron beam focusing system which fits the dimensions (D = 180 mm; L = 380 mm) available f...
متن کاملBroadband extreme-ultraviolet survey spectrometer for short-time-scale experiments.
A fast and inexpensive spectrometer system has been developed to record extreme-UV impurity spectra in a magnetic-fusion-research device. To simplify the vacuum system, light is passed out of the spectrometer's vacuum to the detector with a sodium-salicylate-coated, fiber-optic coupler. This coupler is positioned so that the focal field is nearly flat over its aperture. The system's detector is...
