dc.description.abstract | A new core charge exchange recombination spectroscopy diagnostic has been installed in the ASDEX
Upgrade tokamak that is capable of measuring the impurity ion temperature, toroidal rotation, and
density on both the low field side (LFS) and high field side (HFS) of the plasma. The new system
features 48 lines-of-sight (LOS) with a radial resolution that varies from
±
2 cm on the LFS down
to
±
0.75 cm on the HFS and has sufficient signal to run routinely at 10 ms and for special circum-
stances down to 2.5 ms integration time. The LFS-HFS ion temperature profiles provide an additional
constraint on the magnetic equilibrium reconstruction, and the toroidal rotation frequency profiles
are of sufficiently high quality that information on the poloidal velocity can be extracted from the
LFS-HFS asymmetry. The diagnostic LOS are coupled to two flexible-wavelength spectrometers such
that complete LFS-HFS profiles from two separate impurities can be imaged simultaneously, albeit
with reduced radial coverage. More frequently, the systems measure the same impurity providing very
detailed information on the chosen species. Care has been taken to calibrate the systems as accurately
as possible and to include in the data analysis any effects that could lead to spurious temperatures or
rotations. | es |
