TESLA Test Facility Linac

Common effort of almost all laboratories using s.c. accelerating cavities, e.g.

• (CERN), Cornell, DESY, INFN, (KEK), Saclay, TJNL • 40 partners from 11 countries

More than 75 cavities with gradients up to 35 MV/m

Beam uptime and operational uptime (users or acc.studies)

The TTF Linac was operated 7 days per week, 24 hours.

Approx. 50% of the time was allocated to FEL operation including a large percentage of user time. The FEL requires very stable beam conditions.

In its different set-ups, approx. 13,000 hours beamtime were achieved since 1997.

Based on the TTF experience several FELs using superconducting accelerator technology are proposed.

• another bunch compressor BC3

• new beamlines more than 150 m

• a new collimator concept transv. and energy collim.

• a long undulator 6 modules, 30 m

• a long bypass and a spectrometer line

And again...Finally we‘ll have 48 s.c. cavities at

TTF2.

This is a great test facility for both the X-FEL and the TESLA LC.

Welcome

My talk is about the most..

Some young and unexperienced

speaker need your help!

Thanks

... un-interesting section of TTF2.

Therefore I don‘t like to talk at all!

And my English is so bad.

I don‘t know how to say this.

There are so many faces...

I don‘t like to see them!

OK!

Let‘s enjoy the TTF2 Meeting.
