Abstract The Extended Electron Beam Ion Source (EEBIS) has been installed and commissioned at Brookhaven National Laboratory (BNL) hadron accelerator complex in the spring of 2023. EEBIS replaced its predecessor, RhicEBIS, which provided ions for BNL facilities over a decade since 2009. motivations source upgrade are to provide higher intensities Au 32+ ion beam Relativistic Heavy Collider (RHIC) an intense polarized 3 He 2+ future (EIC) BNL. is will continue be primary variety different...
The front end of any modern ion accelerator includes a radio frequency quadrupole (RFQ). While many pulsed linacs successfully operate RFQs, several accelerators worldwide have significant difficulties operating continuous wave (CW) RFQs to design specifications. In this paper we describe the development and results beam commissioning CW RFQ designed built for National User Facility: Argonne Tandem Linac Accelerator System (ATLAS). Several innovative ideas were implemented in RFQ. By...
The idea of direct plasma injection scheme (DPIS) was proposed in 2000. This new technique has been studied and proven to accelerate intense ion beams. To provide medium mass ions with highly charged states, small tabletop solid lasers were used for production. Based on the measured properties, aluminum carbon accelerated more than 60 mA current. next experiments will use an radio frequency quadrupole designed q/m=1/6 explore beam productions using targets up silver, future work production...

Two groups found: highly charged with ionization potentials in range 500–1000eV registered all between C12 Fe56; same time, about-one-order-less Ge74 Ta181. The most probable reason such big difference is recombination losses during laser-produced plasma expansion into...
