Superconducting CH structure
The superconducting CH structure is a novel multicell cavity for the acceleration of protons and ions in the low and intermediate energy regime. The CH structure is a cross-bar-type cavity; it is the first superconducting low energy multicell cavity operated in an H mode. A superconducting CH-prototype cavity with 19 gaps at 0:1 has been built and tested successfully. Maximum surface fields of ...
متن کاملA Tuner for the 350 MHz Superconducting CH-Structure
The superconducting CH multi-cell prototype cavity, which has passed a very succesfull power test recently leading to an accelerating gradient of Ea = 7 MV/m, will be equipped with a frequency tuning system [1]. The rftuning during operation bases on the principle of a slight elastic deformation at both ends of the tank. This is causing a change in the gap width of the first and last accelerati...
متن کاملA cw Heavy Ion Linac Based on Superconducting CH-Structures
According to the Unilac upgrade program for the SHE research at GSI, a new high energy part of the High Charge State Injector (HLI) has to be worked out. One of the versions of this linac foresees the acceleration of the highly stripped ions with charge-to-mass ratio of 1/6 delivered from the existing HLI at 1.4 MeV/u. The output beam energy should allow experiments at the Coulomb barrier and i...
متن کاملCh-ch-ch-ch-Changes
Change is not made without inconvenience, even from worse to better. Richard Hooker, as quoted in the preface of Samuel Johnson's A Dictionary of the English Language Oh, so they have internet on computers now! Homer Simpson It is with great pleasure that I announce the rebirth of the former print journal of the Canadian Geriatrics Society as a new online publication, the Canadian Geriatrics Jo...
متن کاملSuperconducting gap structure of FeSe
The microscopic mechanism governing the zero-resistance flow of current in some iron-based, high-temperature superconducting materials is not well understood up to now. A central issue concerning the investigation of these materials is their superconducting gap symmetry and structure. Here we present a combined study of low-temperature specific heat and scanning tunnelling microscopy measuremen...
