Megagauss 2.0 : a 10 capacitor system for production of megagauss fields for laser plasma experiments
MetadataShow full item record
High magnetic fields greater than 100 Tesla applied to laser generated plasmas can generate unique and interesting conditions. High power laser systems at the University of Texas in the Center for Higher Energy Density Sciences readily produce short lived fusion plasmas in cluster targets. A strong magnetic field could increase fusion neutron yield and plasma confinement while providing a unique plasma physics environment. For this purpose, Sandia National Laboratories in collaboration with the University of Texas designed and constructed a pulsed power device to produce more than 2 megaamperes. This current produces strong magnetic fields in small coils with duration on the order of microseconds. At the University of Texas, tests with this device determined the operational characteristics. I will describe the behavior of this device with currents of approximately a megaamp and magnetic fields of more than 60 Tesla. Emphasis is placed on understanding the behavior of the fields and coils.
