| | Recent developments on high duty cycle high intensity
proton linac have used, in the high energy part, the
superconducting technology because it is considered to be
advantageous in terms of power consumption,
construction cost and beam loss. In the framework of the
European CARE/HIPPI program, we investigate different
options to use the same superconducting technology even
in the low energy part of the linac (from 5 MeV to 200
MeV). Different kind of superconducting structures (CH
structures, spoke or elliptical cavities) are necessary to
cover this whole energy range. Since the higher energy
part will be equipped with elliptical cavities, we propose a
704 MHz elliptical cavity which could be advantageously
used in the range 80 MeV up to 200 MeV. An optimized
design of this cavity for running in pulsed mode is
presented. The sensitivity of the cavity to pulsed RF is
investigated to assess the efficiency of the stiffening
scheme. | |
