MAGPIE〔Mitchell, I. H. et al., "A high impedance mega-ampere generator for fiber z-pinch experiments", ''Review of Scientific Instruments'' 67, pp.1533-1541, April 1996.〕 (''Mega Ampere Generator for Plasma Implosion Experiments'') is a pulsed power generator based at Imperial College London, United Kingdom. The generator was originally designed to produce a current pulse with a maximum of 1.8 million amperes in 240 nanoseconds (150 nanoseconds rise time). At present the machine is operated with a maximum current of approximately 1.4 million amperes and operates as a z-pinch facility. The generator consists of four voltage multipliers (Marx generators), each one containing 24 capacitors. At the maximum charging voltage of 100 kilo-volts, an output voltage of 2.4 million volts is produced and delivered into the load section 〔("The MAGPIE Generator" ), project-page〕 Research at the MAGPIE generator has focused in the past on the field of inertial confinement fusion, but has recently seen significant adaptations for studies of Laboratory Astrophysics. In particular, the study of astrophysical jets in young stellar objects (see Herbig–Haro object) has been motivated by improved observational capabilities in the recent years.〔Suzuki-Vidal, F. A., "Experimental study of radiatively cooled magnetically driven plasma jets", PhD Thesis, Imperial College London,2009.〕 The simulation of such large-scale events has been undertaken at MAGPIE both from a computational point of view, through the ''GORGON'' code, and from an experimental one by means of the generator.〔Remington, B.A., Drake, R.P., Ryutov, D.D , "Experimental astrophysics with high power lasers and Z pinches", ''Reviews of Modern Physics'', Vol. 78, pp.782-784, July–September 2006.〕 MAGPIE is one of several similar ''pulsed power'' machines worldwide, of which the largest and most powerful is the Z-machine at Sandia National Laboratories, Albuquerque, New Mexico.〔(Z machine homepage ), Sandia National Laboratories〕 ==See also== *List of plasma (physics) articles 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MAGPIE」の詳細全文を読む スポンサード リンク
