“…These specimens were stress relieved at 1573 K for 1 h and polished to a mirror finish on the plasma exposure side. The specimens were installed using the multi-target holder in Magnum-PSI device [12] and was -30 V and the pulse length was 12 s for all exposures. Typically, the specimens were exposed to 3 or 4 shots, separated by about 20 minutes to allow for the magnets to cool.…”

A collective Thomson scattering system has been developed for measuring ion temperature, plasma velocity and impurity concentration in the high density magnetized Magnum-PSI plasma beam, allowing for measurements at low temperature (<5 eV) and high electron density >4 × 1020 m−3, while avoiding laser plasma heating caused by inverse Bremsstrahlung. The collective Thomson scattering system is based on the fundamental mode of a seeded Nd:YAG laser and equipped with an LIVAR M506 camera (EBABS technology). The first collective Thomson scattering measurements are taken at the linear plasma generator Pilot-PSI, 40 mm downstream of the cascaded arc source. At this location, the ion temperature is about equal to the electron temperature in the bulk of the plasma beam.

“…The units can supply a 700 V pulse for the ignition of the plasma. In addition, a capacitor bank has been added recently to the installation to allow repetitive high power loads on the target by shortly increasing the cathode current up to several kA [4].…”

“…Additionally, the thermal imaging camera is used to verify the laser spot size and duration. The laser can also be used on the target during plasma exposures to create an additional heat load to simulate ELM-like events [4].…”

h i g h l i g h t s• High heat flux, high density plasmas in a highly accessible linear plasma device.• Plasma exposure of targets of different sizes under selectable plasma beam angles.• Dedicated plasma and surface diagnostics.• Differential vacuum pumping system. a r t i c l e i n f o b s t r a c tThe construction phase of the linear plasma generator Magnum-PSI at the FOM institute DIFFER has been completed and the facility has been officially opened in March 2012. The scientific program to gain more insight in the plasma-wall interactions relevant for ITER and future fusion reactors has started.In Magnum-PSI, targets of a wide range of materials and shapes can be exposed to high particle, high heat flux plasmas (>10 24 ions m −2 s −1 ; >10 MW/m 2 ). For magnetization of the plasma, oil-cooled electromagnets are temporarily installed to enable pulsed operation until the device is upgraded with a superconducting magnet. The magnets generate a field of up to 1.9 T close to the plasma source for a duration of 6 s. Longer exposure times are available for lower field settings.Plasma characterizations were done with a variety of gases (H, D, He, Ne and Ar) to determine the machine performance and prepare for subsequent scientific experiments. Thomson scattering and optical emission spectroscopy were used to determine the plasma parameters while infrared thermography and target calorimetry were used to determine the power loads to the surface. This paper reports on the status of Magnum-PSI and its diagnostic systems. In addition, an overview of the plasma parameters that can be achieved in the present state will be given.
