Abstract
To investigate excited shockwaves in a collisional-merging field-reversed configuration (FRC), soft X-ray (SXR) measurement was initiated on the FRC amplification via translation collisional merging (FAT-CM) instrument. Since the FRCs collide at a relative speed of 300 - 400 km/s on the FAT-CM, which is faster than the Alfvén velocity in the separatrix, shockwaves are assumed to be excited in the colliding FRCs. These excited shockwaves would play an important role in energy conversion during the collisional merging formation process of the FRC. The relation between the global behavior of the FRC in the collisional merging process and the time evolution of SXR signals are discussed herein.
Keywords
