Low inductance switches for pulsed magnetization of hot plasmas

Summary form only given. For the burning process of high density (about 10¹⁸cm^-3) high temperature (tens of keV) plasma, the trapping by a high mirror-like magnetic field is a challenging objective. Numerical simulations^1-3 may lead to conceptual designs of relatively large magnetized volumes (cm³) at large magnetic field (10 to 100T) with a tailored spatial profile. Taking the example of a Compact Magnetic Fusion (CMF) device³, ⁴ driven by ultra-short, high intensity laser beam interaction with cluster or solid targets, we present a pulsed power device capable of feeding a single turn coil at the level of 100s of kA and μs duration. The key component is a low inductance switch which will be described, paying attention to the triggering process, the plasma characterization, the B-field metrology and its scalability. The proposed device will be discussed in comparison with other solutions from the literature.
