Query: Measurement of the six Dimensional Phase Space at the New GSI High
  Current Linac   For the characterization of the 10 mA ion beam delivered by the new High
Current Linac at GSI, sophisticated, mainly non-intersepting diagnostic devices
were developed. Besides the general set-up of a versatile test bench, we
discuss in particular bunch shape and emittance measurements. A direct
time-of-flight technique with a diamond particle detector is used to observe
the micro-bunch distribution with a resolution of $\sim 25 $ ps equals
0.3$^{o}$ in phase. For the determination of the energy spread a coincidence
technique is applied, using secondary electrons emitted by the ion passing
through an aluminum foil 80 cm upstream of the diamond detector. The transverse
emittance is measured within one macro pulse with a pepper-pot system equipped
with a high performance CCD camera.
