Conceptual Design of Polychromator for Thomson Scattering System in JT-60SA

چکیده
Significant loss in transmissivity of the fiber used for the 18 years operations in JT-60U has been discovered: thereby making optimization of the filter configuration in the polychromator in Thomson scattering system for the high performance plasmas in JT-60SA is an essential task. The loss in the optical components induced by radiation from neutrons and γ-rays in particular needs to be examined. This paper concerns the optimization of the filter configuration in the polychromator with the expected error in measurements due to the radiation damage also being estimated through comparing between fibers used in JT-60U with radiation resistant fibers.

متن کاملDesign and Calibration of a Polychromator for the Thomson Scattering at Wendelstein 7-X
On Wendelstein 7-X, electron density and electron temperature profiles are planned to be measured by Thomson scattering. The specific system employs fiber bundles for the scattered light which is detected by means of a five-channel polychromator system. The detection system is assembled and its components are characterized. A calibration technique employing a super-continuum light source is ass...
متن کاملA Plan for a Fast-Ion D-Alpha (FIDA) Measurement for JT-60SA∗)
A new fast-ion diagnostic based on the spectroscopy of the Doppler shifted Balmer-alpha line of Deuterium is considered for JT-60SA. Two sight lines, one tangential and the other perpendicular, are examined as candidates. It was found that the tangential one has better sensitivity than the perpendicular one. A trial of the FIDA measurement was performed on JT-60U. Signals due to the tangential-...
