Acceleration of macroscopic particle to hypervelocity by high intensity beams
Hypervelocity (～1000 km/s) impact of a macroscopic particle (macron) has profound influences in high energy density physics (HEDP) and impact fusion studies. As the charge-mass ratio of macrons are too low,the length of a electrostatic accelerator can reach hundreds to thousands of kilometers, rendering hypervelocity impact impractical. To reduce the accelerator length,a much higher electric field than what the most powerful klystrons can provide is desired. One of the very few choices is the high intensity charged particle beam blowing-pipe scheme. In this scheme, a high intensity (~ 1 kA), medium energy (1 ~ 5 MV), long pulse (~ 1 ms) positively charged ion beam shots to a heavily charged, millimeter size macron, to create a local high strength electric field (~ 1010 V/m), accelerating the macron. In this paper, we will present a possible approach, and the physics and challenges involved.
