VOLUME IGNITION BY A PLASMA BLOCK IGNITOR

摘要

Methods for single-event laser-target schemes leading to volume ignition are discussed. Conditions have been explored where single-event ns-laser pulses give temperatures sufficient for volume ignition. A modification of this scheme is discussed here whereby use of PW-ps laser pulses produce blocks of DT ion beams in the target. This phenomena is based on the anomalous ion beam emission effect observed by Badziak et al and is attributed to a skin layer interaction. In addition to normal DT fusion, Ms concept could be very advantageous for achieving advanced fuel operation, eg. use of tritium-lean and eventually p-B~(11) fuels.
