| | The Crossbar-H-mode (CH)-structure which has been
developed at the IAP in Frankfurt is a multi-cell drift tube
structure for the efficient acceleration of low and medium
energy protons and ions [1, 2]. A superconducting CHcavity
with 19 cells (f=360 MHz, beta=0.1) has been built and
tested successfully (see fig. 1) [2, 3]. After the localization
of a field emission site an additional surface treatment has
been performed. Recent tests showed a significant increase
in performance. A gradient of 7 MV/m in cw operation has
been reached, corresponding to an effective voltage gain
of 5.6 MV in that cavity. This shows that high real estate
gradients can be achieved in superconducting low energy
mulit-cell cavities. Several projects like IFMIF or EUROTRANS/
ADS with fixed velocity profile driver linacs could
profit from this development. | |
