Magnetic Spring Device

open access: yes, 2009
A cylindrical system is proposed that will store magnetic energy in a localized azimuthal field that can then be quickly released on Alfvenic timescales, accompanied by the formation of a flowing Z-pinch plasma. The magnetized plasma is MHD in character and will have unilateral axial momentum with Alfvenic speeds.

Design and Strength Safety Analysis of Pressure Relief Device for Perforating Gun

open access: yesShiyou jixie
Perforation detonation produces high-temperature and high-pressure gas. If the pressure exceeds the internal pressure strength of the gun body, the perforating gun would break, leading to accidents such as gun expansion and jamming.
