The Electron Beam Ion Source (EBIS) at the Brookhaven National Laboratory (BNL) is a main source of highly charged ions for both Relativistic Heavy Ion Collider (RHIC) and NASA Space Radiation Laboratory (NSRL). It has delivered a wide variety of ions since 2010 with good stability and reliability. The ongoing development of the electron gun with electrostatic compression has a goal to significantly increase the current density of the electron beam. Such electron beam would allow boosting the charge state of ions, which RHIC EBIS injects into RFQ and therefore to increase their final energy at Booster for NSRL applications. This development can also benefit ISOLDE experiment at CERN, where high charge state of the extracted ions is as important as a large acceptance of EBIS and high repetition rate. The current status of RHIC EBIS and the results of the new gun development are presented.
