120-keV NEUTRAL-BEAM INJECTION SYSTEM DEVELOPMENT [PDF]

, 1976
The neutral-beam injection systems for the next generation of U. S. fusion experiments (TFTR, MX, Doublet III) have requirements that considerably exceed the present state of development. TFTR, for example, desires 20 MW of 120-keV deuterium atoms in pulses of 0.5-sec duration.

A Beta Beam complex based on the machine upgrades for the LHC [PDF]

, 2006
The Beta Beam CERN design is based on the present LHC injection complex and its physics reach is mainly limited by the maximum rigidity of the SPS. In fact, some of the scenarios for the machine upgrades of the LHC, particularly the construction of a ...
