Abstract:
Among the three parameters ni τE Ti of the fusion triple product, high ion temperature is a rigid requirement as for the ions to overcome the Coulomb barrier in fusion reaction. Different fusion approaches can be distinguished by the density and confinement time parameter ranges. Inertial confinement fusion ( ICF)(e g The H bomb) is characterized by super high density and transient (extremely short) confinement time; magnetic confinement fusion (MCF) is characterized by low density and steady ( long) confinement time; in between the two extremes, the magneto inertial fusion (MIF) combines the characteristics of ICF and MCF and is characterized by high density and pulsed operation. Magnetized target fusion ( MTF) is a subset of MIF, which compresses magnetized plasmas such as field reversed configuration ( FRC). An FRC-based MTF approach, the HeLong project, is proposed by the ENN’s fusion technology research center. The concept of HeLong will be introduced, and compared to other MTF experiments. The physics design of the Helong-1 experiment, including the FRC formation, acceleration, deceleration/pre compression, modeling of the FRC merging and liner compression, will be presented. The difficulties of the HeLong approach and related future investigation will also be discussed.
