In this concept, propulsion is achieved using large fans driven by superconducting motors. The electrical power for these fans, in turn, is generated by an efficient superconducting hydrogen or natural gas turbine.

The potential for a superconducting proton linac (SPL) at CERN started to be seriously considered at the end of the s. In the first conceptual design report (CDR), published in [1], most. The SPL design in the first conceptual design report (CDR1) [3] was mainly driven by the high-power needs of a CERN-based neutrino factory [ 4 ] and the idea to re-use RF equipment [klystrons.

The potential for a superconducting proton linac (SPL) at CERN started to be seriously considered at a high-power superconducting H L̄inac at CERN book end of the s.

In the first conceptual design report (CDR), published in [1], most of the MHz RF equipment from LEP was re-used in an m long linac, and the proton beam energy was limited to GeV.

During the following years, the design was revisited and optimized to better. An analysis of the revised physics needs and recent progress in the technology of superconducting RF cavities have led to major changes in the speci cation and in the design for a Superconducting Proton Linac (SPL) at CERN.

Compared with the rst conceptual design report (CERN ) the beam energy is almost doubled ( GeV instead of GeV), while the length of the linac is reduced by.

Wright Street, Urbana. A nice demonstration of superconducting permanent currents is shown in Fig A small permanent magnet that is lowered towards a superconducting lead bowl generates induction currents according to Lenz’s rule, leading to a repulsive force acting on the magnet.

Headed by the leading cable manufacturer Nexans and bringing together transmission operators, industrial manufacturers and research.Abstract: This paper describes the conceptual design of a high temperature superconducting (HTS) generator for mobile radar (MR) applications.

The power system for MR consists of a diesel engine, a generator and power conditioning electronics. Significant improvements in power density, performance and system efficiency result if the generator and the power electronics are cryogenically cooled.Losses in superconducting power cables are mainly due to AC, thermal and dielectric effects.

The interplay of cable geometry, operating conditions, transmitted power, and the resulting losses are considered. The design studies indicate that for Bi cables with warm dielectric an operating temperature well below 77 K is favoured.
