Adjustable ECR ion source control system: Ion Source Hydrogen Positive project

摘要

ISHP (Ion Source Hydrogen Positive) project consists of a highly versatile ECR type ion source. It has been built with several purposes, on the one hand, at the first stages, to serve as a workbench to test accelerator related technologies and validate in-house made developments. On the other hand, to design an ion source valid as the first step in an actual LINAC. Since this paper is focused on the control system of ISHP, besides the ion source, all the hardware and its control architecture is presented. Nowadays the ion source is able to generate a pulse of positive ions of Hydrogen from 2μs to a ms range with a repetition rate ranging from 1Hz to 50Hz with a maximum of 45mA of current. Furthermore, the first experiments with White Rabbit (WR) synchronization system are presented.
