DESIGN AND CALIBRATION OF THE JET NEUTRAL PARTICLE ANALYZER
The neutral particle analyzer with energy and mass selection capability constructed for JET is described in this paper. The analyzer is able to detect in the same shot both H atoms from 0.3 to 320 KeV and D atoms from 0.14 to 160 keV. The design of the analyzer has profited from extensive calculation of ion trajectories by means of a computer code, which is fully illustrated. The problems inherent in the analyzer calibration for a wide energy range are discussed, and the calibration procedure is described. In conclusion, the calibration results obtained with five analyzers are presented together with theoretical considerations on ion optics and atomic processes, which have enabled us to write simple interpolation formula for the experimental data.
