“…We present the bremsstrahlung measurements from a fast sputtering campaign conducted on the Superconducting Source for Ions (SuSI) at the National Superconducting Cyclotron Laboratory (NSCL). The SuSI source is a fully superconducting ECR ion source nominally operating at 18 GHz [3] and 24 GHz [4] microwave frequencies. Following the path set by Geller's scaling laws for ECRIS [5] the plasma density and beam current of ECR ion sources increase with the square of the operating frequency and as proposed more recently [6] with the square of the magnetic field.…”

Heavy ion facilities such as the National Superconducting Cyclotron Laboratory (NSCL) often use ECR Ion Sources (ECRIS) for the production of highly charged ions to increase the efficiency of accelerating structures. Axial bremsstrahlung emission was studied on the Superconducting Source for Ions (SuSI) at the NSCL for 18 GHz and 13 GHz operation with oxygen. The hot electron temperatures were estimated from the bremsstrahlung high energy tail and seem to depend only on magnetic minimum in the same way as was found on VENUS [1], even in the case where 18 GHz and 13 GHz frequencies were compared for similarly sized ECR zones. Additionally, the time independent x-ray power increased at a significantly larger rate when operating the source in known regions of instability such as where the magnetic minimum approaches the ECR zone [2]. The results are discussed in the context of electron losses due to magnetic confinement.

“…For Uranium Oxide sublimation, the oven temperature is required > 2000 ℃ to produce enough vapor. The mechanical design has been completed based on the inductive oven used at NSCL for Nickel and Germanium beams development (1500 ℃) [7]. Thermal calculations have been performed for the design and integration.…”

T o meet a beam power requirement of 400 kW for heavy ions, a high intensity 28 GHz superconducting Electron Cyclotron Resonance (ECR) ion source is under development at the Facility for Rare Isotope Beams (FRIB) in collaboration with Lawrence Berkeley National Laboratory (LBNL). The magnet was built and tested at LBNL and integrated into the ion source cryostat on the FRIB high voltage platform. Magnet cooldown to 4.2K was completed successfully in December of 2020. The static heat load at 4.2K has been measured to be around 1.2 W, in good agreement with the design value. The heat load is managed through 2 Gifford-McMahon/Joule-Thomson (GM-JT) cryocoolers that have been in operation for several months. Magnet energization is scheduled in November of 2021. Warm components preparation and assembly test are ongoing in parallel. The ion source commissioning with 18 GHz Klystron shall start in December of 2021. Details of the ion source development, status, and commissioning plan will be presented in the paper.

“…The technical considerations required to achieve the given goals were formulated by analyzing existing high-energy, high-intensity ion sources. As a result, the technical configuration of SUSI 4 at NSCL/MSU was found to be the most promising as its performance at 18 GHz met the requirements of the ECR ion source at JYFL (see Fig. 3).…”
