Recent advances in megagauss physics

Generation of megatesla magnetic fields by intense-laser-driven microtube implosions

“…Laboratory generation of strong magnetic fields have been intensively studied [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], because such fields may realize new experimental tools for fundamen-tal studies and support diverse applications. Examples include plasma and beam physics [19][20][21][22][23][24], astro- [25,26] and solar-physics [27,28], atomic and molecular physics [29], and materials science [30,31].…”

Advances in the Filamentary Modelling of Electromagnetic Flux Compression

“…Predictions provided by the two models were compared with experimental results from a 4 MJ EFC experiment in which flux densities up to 550 T were produced. 6) As a full Figure 3 shows the history of the flux density during the 4 MJ experiment, 6) with, as in all other later results, the time origin being the moment that the switch S1 of Fig. 1 is closed.…”

Laser scaling for generation of megatesla magnetic fields by microtube implosions

“…In the past 50 years, researchers have strived to realize strong magnetic fields in laboratories for fundamental studies and diverse applications [1][2][3][4][5][6][7][8][9]. Approaches include high explosives [10,11], electromagnetic implosions [12,13], high-power lasers [14][15][16][17][18][19], and Z pinches [20,21]. The principal physical mechanism of these methods is based on magnetic flux compression (MFC) [10] using hollow cylindrical structures and pre-seeded magnetic fields.…”
