Abstract
This paper describes an analyzer of the energy of secondary slow ions, which is used to measure the degree of compensation of the spatial charge of a hydrogen ion beam in a low energy beam transport channel (LEBT) to the input of an accelerator with high-frequency quadrupole focusing. The electrostatic analyzer with a retarding field has increased accuracy due to the use of a double analyzing grid. The results of measuring the degree of compensation of the space charge of a hydrogen ion beam with a pulse current of 60 mA and an energy of 400 keV are presented. The analyzer also allows non-disturbing measurements of the radial size of the ion beam. [ABSTRACT FROM AUTHOR]
