Title: STATUS OF THE BNL HIGH CURRENT EBIS TEST STAND.

Abstract

As part of a new, compact heavy ion injector for AGS/RHIC complex at Brookhaven National Laboratory we are developing an Electron Beam Ion Source (EBIS) that would satisfy present and future requirements. Such a source should be capable of producing intensities of e.g. Al{sup 35+} ions of about 3 x 10{sup 9} particles/pulse or U{sup 45+} of about 2 x 10{sup 9} particles/pulse. To achieve this, the required e-beam intensity is 10A, at a pulse length of 100ms. An EBIS test stand has been constructed, designed for the full electron beam power and having close to 1/2 of the trap length of an EBIS for RHIC. Initial electron beam tests have resulted in a 50{micro}s, 13A electron beam. Ion production and extraction has been shown with a 3.1 A, 50 ms electron beam, achieving an ion yield of 19 nC/pulse (neutralization degree of 61%); fast extraction trials have yielded extracted ion pulses of 1mA peak current and 18{micro}s at FWHM. Details of the test stand construction, results of the electron beam studies, and properties of the extracted ion pulse are presented.
