  The integration of the accelerator components in to the cryogenic module prototype (Advanced Demonstrator) is a major milestone of the R&D for the superconducting heavy ion continuous wave linear accelerator HELIAC at GSI. The HELIAC is joint project of Helmholtz Institute Mainz (HIM) and GSI developed in collaboration with IAP Goethe University Frankfurt. This module is equipped with three superconducting (sc) Cross bar H-mode (CH) acceleration cavities CH0-CH2 and a sc rebuncher cavity, as well as two sc solenoids. The commissioning of the cryogenic module with Argon beam at GSI is scheduled for August 2023. In preparation for the beam test activities, the beamline, which connects the High Charge State Injector (HLI) with the testing area, has been installed. The beamline comprises a pair of phase probes for Time Of Flight (TOF) measurement of the incoming beam energy, quadrupole lenses and a 4-gap RF-buncher cavity. The beam diagnostics bench behind the cryo module is equipped with phase probe pairs, a slit-grid device, a bunch shape monitor (Feshenko monitor) for measurements of the longitudinal beam profile. The bench allows complete 6d characterization of the ion beam.

  The demand for neutrons of various types for research is growing day by day worldwide. To meet the growing demand the Jülich High Brilliance Neutron Source (HBS) is in development. It is based on a high power linear proton accelerator with an end energy of 70 MeV and a proton beam current of 100 mA. The main part of the accelerator consists of about 45 CH-type cavities. As the current beam dynamic layout is still work in progress the number of cavities can change for the final design. For this beam dynamic layout the design of the CH-type cavities was optimized to handle the high accelerating gradient. The results of the performance of the CH-type cavities will be presented in this paper.

A new superconducting (SC) continuous wave (CW) linac, providing high efficient heavy ion acceleration above the coulomb barrier, is going to be built at GSI to fulfill the upcoming demands in the research field of super heavy element (SHE) synthesis. The so called HELIAC (HElmholtz LInear ACcelerator) delivers ion beams in the energy range of 3.5 MeV/u and 7.3 MeV/u with a mass to charge ratio (A/z) of up to 6. Superconducting multi-gap crossbar-H-mode (CH) cavities with a resonance frequency of 217 MHz are used for beam acceleration. In addition, SC single spoke buncher cavities should ensure longitudinal beam matching to the corresponding CH sections. Therefore, the first 217 MHz single spoke cavity with beta 0.07 has been developed at HIM/GSI and built at an industrial partner. In this paper the design of the cavity and first RF measurements during manufacturing are presented.

  The superconducting continuous wave (cw) heavy ion HElmholtz LInear ACcelerator (HELIAC) is intended to be built at GSI in Darmstadt. With its high average beam current and repetition rate, the HELIAC is designed to fulfill the requirements of the super heavy element (SHE) research user program and the material sciences community at GSI. The accelerating cavities are of the superconducting Crossbar H-mode (CH) type, developed by GUF. Within the Advanced Demonstrator project, the first cryomodule, consisting of four cavities is scheduled for commissioning with beam in 2023. The former RF power couplers introduced a high heat input into the cryostat. Therefore, the coupler is redesigned at HIM in order to not only reduce the heat input but to provide an overall improved power coupler for the HELIAC. It is designed for maximal power of 5 kW cw at the frequency of 216.816 MHz. A prototype has been tested and commissioned recently. This includes several RF-tests at room temperature and in cryogenic environments. The results of these tests will be presented in this paper.

  As various experimental reactors in Europe are already or will be decommissioned over the next years, new neutron sources will be necessary to meet the demand for neutrons in research and development. The High Brilliance Neutron Source is an accelerator driven neutron source planned at the Forschungszentrum Jülich. The accelerator will accelerate a proton beam of 100 mA up to an end energy of 70 MeV, using 45 normal conducting CH-type cavities. Due to the high beam current, the beam dynamics concept requires special care. In this paper, the current status of the beam dynamics for the drift tube linac is presented.
