Measurement of Ion Beam from Laser Ion Source for Rhic Ebis
نویسندگان
چکیده
Laser ion source (LIS) is a candidate of the primary ion source for the RHIC EBIS. LIS will provide intense charge state 1+ ions to the EBIS for further ionization. We measured plasma properties of a variety of atomic species from C to Au using the second harmonics of Nd:YAG laser (532 nm wave length, up to 0.5 J / 6 ns). Since properties of laser produced plasma is different from different species, laser power density for singly charged ion production should be verified experimentally for each atomic species. After plasma analysis experiments, Au ions was extracted from plasma and emittance of the ion beam was measured using pepper pot type emittance monitor.

Report on Ebis Studies for a Rhic Preinjector
At Brookhaven, an Electron Beam Ion Source (EBIS) is now operational. This source is being used as a test bed to answer questions relevant to the eventual design of an EBIS-based heavy ion injector for RHIC. Such a source can easily produce ions such as Au, but the challenge lies in reaching intensities of interest for RHIC (3 x 10 particles/pulse). The source studies are planned to address iss...

In electron beam ion sources, step-wise ionization to high charge states is accomplished by magnetically confined electron beam. Electron space charge and high voltage electrodes confine the ions. The relativistic heavy ion collider (RHIC) ion source Debye length meets requirements for instabilities with free source of energy to grow. Electrons stripped from ions provide energy for a variety of...
