To investigate steady-state as well as fast transport processes in the plasma edge region of magnetically confined fusion plasmas, a thermal helium beam diagnostic has been implemented at ASDEX Upgrade. Neutral helium is injected into the plasma by a piezo valve to perform line ratio spectroscopy for electron density and temperature determination. An optical head with 53 lines of sight aligned...

Measurements of magnetic field profiles on the self-magnetic pinch (SMP) diode are critical to understanding the electron beam pinch dynamics throughout the current pulse. In the SMP diode, the planar anode, consisting of a high Z material, converts the beam energy into bremsstrahlung x-rays, resulting in dense plasma formation, on the anode surface. A fiber array images along the anode...

Diagnosing the density profile at the edge of high temperature fusion plasmas by accelerated Lithium beam is a known technique since decades. By knowledge of the relevant atomic physics rate coefficients the plasma electron density profile can be calculated from the relatively calibrated light profile along the beam. Several additional possibilities have already been demonstrated: CXRS for ion...
