“…Potentially more concerning is the mass transfer phenomena driven by the solubilities of Cr, Ni and Fe in Li, and this is being tested in IFMIF relevant conditions in the ongoing experiments of LiFus 6 in Brasimone (ENEA) with 30 wppm N present in liquid Li (compared to 10 wppm specified) and 80 K higher temperature. The trapping of N in Li to values around 30 wppm was shown to be feasible with Ti pellets doped with Fe in the EVEDA phase [48] and to values around 65 wppm can be done with Cr as gettering element [122] (see section 3.6).…”

IFMIF, the International Fusion Materials Irradiation Facility, is presently in its engineering validation and engineering design activities (EVEDA) phase under the Broader Approach Agreement. The engineering design activity (EDA) phase was successfully accomplished within the allocated time. The engineering validation activity (EVA) phase has focused on validating the Accelerator Facility (AF), the Target Facility and the Test Facility (TF) by constructing prototypes. The ELTL at JAEA, Oarai successfully demonstrated the long-term stability of a Li flow under the IFMIF’s nominal operational conditions keeping the specified free-surface fluctuations below ±1 mm in a continuous manner for 25 d. A full-scale prototype of the high flux test module (HFTM) was successfully tested in the HELOKA loop (KIT, Karlsruhe), where it was demonstrated that the irradiation temperature can be set individually and kept uniform. LIPAc, designed and constructed in European labs under the coordination of F4E, presently under installation and commissioning in the Rokkasho Fusion Institute, aims at validating the concept of IFMIF accelerators with a D+ beam of 125 mA continuous wave (CW) and 9 MeV. The commissioning phases of the H+/D+ beams at 100 keV are progressing and should be concluded in 2017; in turn, the commissioning of the 5 MeV beam is due to start during 2017. The D+ beam through the superconducting cavities is expected to be achieved within the Broader Approach Agreement time frame with the superconducting cryomodule being assembled in Rokkasho. The realisation of a fusion-relevant neutron source is a necessary step for the successful development of fusion. The ongoing success of the IFMIF/EVEDA involves ruling out concerns about potential technical showstoppers which were raised in the past. Thus, a situation has emerged where soon steps towards constructing a Li(d,xn) fusion-relevant neutron source could be taken, which is also justified in the light of costs which are marginal to those of a fusion plant.

“…In particular, LLi jets in the order of 1 cm thickness are used as targets for MeV proton beams to produce high flux neutron beams. Power deposited on target of about 0.5 MW and of > 1 MW have been obtained or planned with LLi jet velocities of 5 m/s or 30 m/s respectively [19]. In addition to evaporation, beam spot sizes smaller than 1 mm 2 would reach the bubbling regime for LLi.…”

A new scheme to produce very low emittance muon beams using a positron beam of about 45 GeV interacting on electrons on target is presented. One of the innovative topics to be investigated is the behaviour of the positron beam stored in a low emittance ring with a thin target, that is directly inserted in the ring chamber to produce muons. Muons can be immediately collected at the exit of the target and transported to two µ + and µ − accumulator rings and then accelerated and injected in muon collider rings. We focus in this paper on the simulation of the e + beam interacting with the target, the effect of the target on the 6-D phase space and the optimization of the e + ring design to maximize the energy acceptance. We will investigate the performance of this scheme, ring plus target system, comparing different multi-turn simulations. The source is considered for use in a multi-TeV collider in ref. [7].

“…To accordingly validate the free surface target flow, a target with 1:1 length and curvature and scaled down width (1:2.6) was built. This target was integrated into the EVEDA lithium test loop [3] (see section 2.2) where it could be operated with the full range of flow speeds between 10-20 m s −1 (nominal speed 15 m s −1 ). This target was equipped with extra ports for optical inspection (with high speed video cameras) and especially with a laser probe based on optical comb/time of flight technique for time resolved measurements of the lithium-surface position.…”

During the Engineering Validation and Engineering Design Activities (EVEDA) phase of the International Fusion Materials Irradiation Facility (IFMIF), major elements of the Lithium Target Facility (the neutron source) and the Test Facility (implementing the irradiation experiments) were prototyped and tested. These works were successfully concluded in the frame of the Japanese and European Broader approach activities between 2007 -20015.The validation activities included basic research (SSTT, corrosion), components (irradiation modules) and large scale facilities (lithium and helium loops). The results were fed back to the EVEDA design process and support the ongoing design activities towards an IFMIF plant to be realized timely, as necessary element of the fusion roadmaps.
