Non-Liouvillian techniques for high-energy density experiments with ion beams: proposal for the CERN accelerator complex

An overview of non-Liouvillian mechanisms useful for application to existing high-energy accelerators is presented. An example under discussion for experiments on high-energy density in matter with intense heavy-ion beams delivered by the CERN accelerator complex is described. A possible scheme has been found for accumulation of relativistic ion beams of gamma 6–10 with total energy ca. 10 kJ and pulse duration ca. 4 ns using a combination of PS and SPS synchrotron rings. Taking into account only electromagnetic interactions of the projectiles with solid matter gives a level of specific deposition power more than 100 TW/g.

Electromagnetic and mechanical design of a 56 mm aperture model dipole for the LHC

The Large Hadron Collider (LHC) project is proposed as the future extension of the CERN accelerator complex. The LHC requires twin aperture superconducting dipoles of highest possible field to guide the proton beams in the existing LEP tunnel of 26.7 km circumference. This paper describes the electromagnetic and mechanical design of a 56 mm aperture model dipole for the LHC.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
