Abstract

Abstract: The calibration system of multi-channel compact pinhole neutral particle analyzer (CP-NPA) is introduced, which includes a high-energy, low-current neutral beam line and a supporting rotation platform. The beam source is composed of a high-frequency ion source, a focusing electric single lens, an accelerating tube, a focusing electric quadrupole lens and a neutralization chamber. The high-frequency ion source has been built, and the plasma has been successfully established in the experiment. Simulation, manufacture and test of the single lens have been finished. In the experiment, fixing the extracting voltage at 1.0kV, adjusting the focusing voltage of the single lens, the maximum current is 36.4μA. Design of the other parts of the beam source has been finished as well.

Key words: Neutral particle analyzer, Calibration, Fast ion
