MO102 | XFEL: plans for 101 cryomodules | 6 |
| | |
| The XFEL project [1,2] will use 101 accelerator
modules in its superconducting electron linac. A review of
the design is being given as well as the most recent test
results at the module test stand and at the FLASH [3]
accelerator. The fabrication and preparation of the
superconducting cavities will be done in industry. The
current plans for the acceptance testing of the cavities and
the final test of the completed modules will be discussed. | |

| The new simplified version of the piezo-assisted Blade
Tuner has been tested at DESY in the horizontal cryostat
CHECHIA in September. The tuner mechanism has been
characterized at room temperature and one high gradient
cavity of the last production has been recently tuned and
equipped with a properly modified helium tank. In view
of its possible adoption for the ILC, the cheaper stainless
steel version of the tuner has been chosen for the cold
tests. In this paper the results are presented and discussed. | |
TUP77 | Recent Experience with Nine-cell Cavity Performance at DESY | 334 |
| | |
| The rf performance of the last nine-cell cavity
production for TTF/FLASH1 is analysed with respect to
maximum gradient, usable gradient and field limitation.
30 cavities have been manufactured at one company from
high RRR niobium (RRR > 300) by two vendors. All
cavities have been treated by a long (>150 um)
horiziontal EP (Electropolishing) and 800 degree C firing. The
cavity performance after final short (app. 50 um) EP with
or without subsequent ethanol rinse as well as a short
chemical etch (~10 um BCP) is compared. | |
