An Electron Beam Ion Source charge breeder has been in operation at Argonne National Laboratory since 2017 and has been delivering radioactive ions for the ATLAS experimental program. Single charge state efficiencies average 16% with the radioactive species accounting for up to 99% of the beam incident on target. The electron beam collector which was repaired in early 2019 continues to perform...
The ReAccelerator (ReA) at the National Superconducting Cyclotron Laboratory at Michigan State University is a worldwide unique facility, as it is the only post-accelerator that reaccelerates rare-isotope beams produced by fast-projectile fragmentation. While stable nuclei are delivered from local ion sources, rare nuclei are produced by in-flight fragmentation or fission of primary beams...
The Canadian Rare-isotope facility with Electron Beam ion source (CANREB) is currently being commissioned at TRIUMF in Vancouver, Canada. CANREB can accept stable or rare isotope beams from the existing ISAC facility, or from the Advanced Rare Isotope Laboratory (ARIEL) in the future. The incoming beams are pulsed using an RFQ cooler/buncher, and energy adjusted using a pulsed drift tube for...
The Facility for Rare Isotope Beams, FRIB, is being implemented at Michigan State University (MSU). One-part of FRIB is the ReA post-accelerator, which includes an Electron Beam Ion Trap (EBIT) charge breeder. Currently, RIB are produced by fast-projectile fragmentation and fission in the Coupled-Cyclotron Facility (CCF). After production, these beams are then separated in-flight and...
Atomic mass measurements of short-live radioactive isotopes are useful to determine the nuclear structure and deviations from the existing nuclear models, to explore the nuclear astrophysics reaction paths that are responsible for creating visible matter and to test predictions of fundamental physics beyond Standard model. Electron beam ion source/trap (EBIST) can charge breed these exotic...
Good operator interfaces, alarms, and operating instructions. These are essential for supporting your operations team as they learn to run your system. So why are they often afterthoughts, thrown together at the last minute and dropped in the control room? Spending time early to consider final operation can save time and frustration in the long run. Here I outline an operator-focused HMI...
Highly charged ion sources play an important role in the advancement of heavy ion accelerators worldwide. The beam requirements of highly charged heavy ions from new accelerators have driven the performance of ion sources to their limits and beyond. In parallel to developing new technologies to enhance the performance of ECR ion source, this paper presents a conceptual design of an ion trap...
At the Isotope mass Separator On-Line DEvice (ISOLDE) facility based at CERN, rare isotopes are produced from 1.4 GeV-proton collisions onto a target. Radioactive ion beams of interest are either delivered to low-energy experimental stations or manipulated and accelerated to higher energies, through REX/HIE-ISOLDE post-accelerator. Prior to post-acceleration through REX/HIE-ISOLDE linac, ions...
Contaminants reduction in Electron Cyclotron Resonance Charge Breeders (ECRCB) is a key point for the future experiments foreseen at INFN-LNL and GANIL Isotope Separation On Line (ISOL) facilities. Depending on the resolution of the spectrometer installed downstream an ECRCB, a radioactive ion beam (RIB) could be contaminated by the impurities introduced in the breeding stage, due to the...
The Argonne Tandem Linear Accelerator System (ATLAS) is upgrading the suite of diagnostics used to optimize and deliver radioactive ion beams from the Californium Rare Isotope Breeder Upgrade (CARIBU) Electron Beam Ion Source (EBIS) charge breeder. Historically beta decay detectors were used exclusively throughout the facility from low (<50 keV) to high energies (>100 MeV), but they have...
An upgrade of RHIC EBIS, the extended EBIS, is presently under development at Brookhaven National Laboratory to increase the intensity of the Au32+ ion beams by 40%–50% to 2.1 ⋅ 109 Au32+ ions/pulse at the booster ring entrance. Generation of intense beams of polarized 3He2+ ions with up to ∼ 5 ⋅ 1011 ions/pulse for the RHIC and the future electron–ion collider is a goal of the EBIS upgrade...
The Electron Cyclotron Resonance Ion Source (ECRIS) is a versatile and reliable source to charge-breed rare isotopes in TRIUMF’s Isotopes Separation and Acceleration (ISAC) facility. Significant research work has been done by different groups worldwide to improve the efficiency and performance of the ECRIS as a charge state booster (CSB). The most recent of these research works is the...
The CANadian Rare isotope facility with Electron-Beam ion source (CANREB) at TRIUMF delivers beams of highly-charged ions of rare isotopes to experiments. The Electron Beam Ion source (EBIS) is an essential part of CANREB where ions are charge-bred by collisions with an electron beam. We present simulation results for the CANREB EBIS using TRAK (version 8.0 professional).
The EBIS geometry...
