First tests of the Trapped Ion Source

Recently the detailed design and the construction problems of a Trapped Ion Source (TIS) have been presented previously. In practice, TIS can be seen as a modified version of an Electron Beam Ion Trap (EBIT) or of an Electron Beam Ion Source (EBIS). The main new feature of TIS, with respect to an EBIS (or EBIT), is the transverse ion confinement given by a quadrupole field instead of the electron beam space charge. One can foresee that TIS could overcome some drawbacks of the EBIT and EBIS making it a more flexible device. In this paper a detailed discussion on the radiofrequency containment of high charge state ions with the first RF containment test is presented
