Abstract

A design for a device to move a sensitive element (compression tube, Faraday cylinder or other sensor) relative to an atomic or ionic beam to measure its intensity profile is described. The device is a two-axis manipulator with mechanical adjustment, built on the principle of vacuum motion input with a deformable sealing element (a metal bellows). The manipulator-based measurement system has successfully applied to measure the intensity profiles of beams from the atomic and ionic units of the POLIS polarized ion source. The measurements were conducted within the PolFusion experiment which is aimed at studying double-polarized nuclear fusion and is being carried out at the National Research Center “Kurchatov Institute” — PNPI.

Keywords: vacuum motion input, spin nuclear polarization, atomic beam, ion beam, Faraday cylinder, compression tube, polarized nuclear fusion
