abstract = {New CH-DTL cavities designs of the planned Helmholtz Linear
Accelerator (HELIAC) are developed in collaboration of HIM,
GSI and IAP Frankfurt. The linac, operated in cw-mode with a
final energy of 7.3 MeV/u, is intended for various
experiments, in particular with heavy ions at energies close
to the Coulomb barrier for research on SHE. Twelve sc CH
cavities are foreseen, divided into four different
cryostats. Each cavity will be equipped with dynamic bellow
tuner. After successful beam tests with CH0, CH3 to CH11 are
being designed. Based on the experience gained so far,
optimization will be made, which will lead to both an
increase in performance in terms of reducing the peak fields
limiting superconductivity and a reduction in manufacturing
costs and time. In order to optimize manufacturing,
attention was paid to design many parts of the cavity, such
as lids, spokes, tuner and helium shell, with the same
geometrical dimensions. In addition, a tuner test rig was
developed, which will be used to investigate the mechanical
properties of the bellow tuner. For this purpose, different
simulations were made in order to realize conditions as
close as possible to reality in the test rig.},
