“…Note, that the attainment of higher ion energies in linear devices requires target biasing or additional RF heating (as foreseen in MAGNUM-PSI [4]) and that the particle flux densities depicted are normal to the target surfaces. The very particle high fluxes deliv- ered from the cascaded arc source in MAGNUM-PSI will allow to realize ITER flux conditions at inclined surfaces because it matches both densities and temperatures of the ITER divertor strike point as seen in Fig.…”

“…[4] for an extended description of the device), currently under constructions at FOM Rijnhuizen, The Netherlands, will employ a high-pressure cascaded arc source [5]. A prototype of the source has successfully been tested at the Pilot-PSI machine [6], the forerunner of MAGNUM-PSI and proved the plasma parameters anticipated for MAGNUM-PSI and listed in Table 2.…”

“…Moreover, a pulsed operation mode of the source is under development aiming at a transient power flux density of 2 GWm −2 for 0.5 ms to simulate transient loads [7]. Neutron damaged or toxic material cannot be handled but it is envisaged to simulate the impact of neutron activation by in situ high energy ion beam irradiation [4]. MAGNUM-PSI is equipped with a flexible target system consisting of a user-defined target head, a target manipulator and a target exchange chamber, which allows for unique flexibility to investigate different target materials and to handle inclined targets.…”

a b s t r a c tNew linear plasma devices are currently being constructed or planned in the Trilateral Euregio Cluster (TEC) to meet the challenges with respect to plasma surface interactions in DEMO and ITER: i) MAGNUM-PSI (FOM), a high particle and power flux device with super-conducting magnetic field coils which will reach ITER-like divertor conditions at high magnetic field, ii) the newly proposed linear plasma device JULE-PSI (FZJ), which will allow to expose toxic and neutron activated target samples to ITER-like fluences and ion energies including in vacuo analysis of neutron activated samples, and iii) the plasmatron VISION I, a compact plasma device which will be operated inside the tritium lab at SCK-CEN Mol, capable to investigate tritium plasmas and moderately activated wall materials. This contribution shows the capabilities of the new devices and their forerunner experiments (Pilot-PSI at FOM and PSI-2 Jülich at FZJ) in view of the main objectives of the new TEC program on plasma surface interactions.

The FOM Institute DIFFER -Dutch Institute for Fundamental Energy Research has completed the construction phase of Magnum-PSI, a magnetized, steady-state, large area, high-flux linear plasma beam generator to study plasma surface interactions under ITER divertor conditions. Magnum-PSI consists of several hardware subsystems, and a variety of diagnostic systems. The COntrol, Data Acquisition and Communication (CODAC) system integrates these subsystems and provides a complete interface for the Magnum-PSI users. Integrating it all, from the lowest hardware level of sensors and actuators, via the level of networked PLCs and computer systems, up to functions and classes in programming languages, demands a sound and modular software architecture, which is extendable and scalable for future changes. This paper describes this architecture, and the modular design of the software subsystems. The design is implemented in the CODAC system at the level of services and subsystems (the overall software architecture), as well as internally in the software subsystems.

A coherence imaging camera has been set up at Pilot-PSI. The system is to be used for imaging the plasma density through the Stark effect broadening of the H ␥ line. Local density values are then obtained by the Abel inversion of the measured interferometric fringe contrast. This report will present the instrument setup and proof-of-principle demonstration. The inverted spatial electron density profiles obtained near the cascaded arc source of Pilot-PSI in discharges with axial magnetic field of B = 0.4 T are compared with an independent measurement of electron density by Thomson scattering and good agreement is found.
