Development of a Potential-Life Ion Source

摘要

Generally, an ion source is supplied with high voltage to accelerate ions. However, the high voltage on the ion source makes some difficulties in applying pulse voltage or introducing samples etc. We developed a new ion source to solve these problems. This new ion source consists of a grounded ionization region, and acceleration region and a cylinder. While the electric potential of the cylinder is varied, the electric field in the cylinder does not change and the kinetic energy of the ions in the cylinder is independent of the potential of the cylinder.
