RF breakdown is a key issue for the multi-TeV highluminosity
e+e- Compact Linear Collider (CLIC). Breakdowns
in the high-gradient accelerator structures can deflect
the beam and decrease the desired luminosity. The
limitations of the accelerating structures due to breakdowns
have been studied so far without a beam present in the
structure. The presence of the beam modifies the distribution
of the electrical and magnetic field distributions, which
determine the breakdown rate. Therefore an experiment
has been designed for high power testing a CLIC prototype
accelerating structure with a beam present in the CLIC Test
Facility (CTF3). A special beam line allows extracting a
beam with nominal CLIC beam current and duration from
the CTF3 linac. The paper describes the beam optics design
for this experimental beam line and the commissioning of
the experiment with beam.
