Experevients On A Long Magneucally Insulated Transmission Line Downstream Of A Peos

Magnetically Insulated Transmission Lines (MITLs) have been used to transport electrical energy over long distances in vacuum. In the past MITLs have only been used on machines where all pulse compression occurs outside the vacuum. On inductive store pulsed power machines, however, pulse compression may be achieved in vacuum by means of a Plasma Erosion Opening Switch (PEOS). Transport of power from the switch to load may require long MITLs that must function in the presence of plasma debris from the opening switch. Experiments have been performed with a one-meter-long MITL downstream of a PEOS on EYESS demonstrating successful operation of a PEOS MITL system. Several different MITLs were tested. We observed no significant current losses in the MITL for normal operation, and power was delivered efficiently to the load. There is, however, a poorly understood time delay in the system which cannot be attributed to propagation in the MITL and does not appear when the PEOS is operated without a MITL.
