VUV spectroscopy in impurity injection experiments at KSTAR using prototype ITER VUV spectrometer
VUV spectroscopy in impurity injection experiments at KSTAR using prototype ITER VUV spectrometer
The ITER vacuum ultra-violet (VUV) core survey spectrometer has been designed as a 5-channel spectral system so that the high spectral resolving power of 200–500 could be achieved in the wavelength range of 2.4–160 nm. To verify the design of the ITER VUV core survey spectrometer, a two-channel prot...

The ITER vacuum ultra-violet (VUV) core survey spectrometer has been designed as a 5-channel spectral system so that the high spectral resolving power of 200–500 could be achieved in the wavelength range of 2.4–160 nm. To verify the design of the ITER VUV core survey spectrometer, a two-channel prototype spectrometer was developed. As a subsequent step of the prototype test, the prototype VUV spectrometer has been operated at KSTAR since the 2012 experimental campaign. From impurity injection experiments in the years 2015 and 2016, strong emission lines, such as Kr xxv 15.8 nm, Kr xxvi 17.9 nm, Ne vii 46.5 nm, Ne vi 40.2 nm, and an array of largely unresolved tungsten lines (14-32 nm) could be measured successfully, showing the typical photon number of 1013–1015 photons/cm2 s. |
