27 Jun 2013 | | Abstract: | We consider a possibilty to use an echelon of mutually coherent laser pulses
generated by the emerging CAN (Coherent Amplification Network) technology for
direct particle acceleration in periodic plasma structures. The plasma
structure survives a single shot only. However, due to it’s simplicity and
projected very low production costs, the structure can be replaced for every
laser shot at a kiloherz repetition rate. We discuss resonant and free
streaming configurations. The resonant plasma structures can trap energy of
longer laser pulses but are limited to moderate laser intensities of about
10^{14},{
m W/cm^{2}} and are very sensitive to the structure quality. The
free streaming configurations can survive laser intensities above 10^{18},{
m
W/cm^{2}} for several tens of femtoseconds so that sustained accelerating rates
well above {
m TeV/m} are feasible. In our full electromagnetic relativistic
particle-in-cell (PIC) simulations we show a test electron bunch gaining up to
120,{
m GeV} over a distance of 5.3,{
m cm} only. | | Source: | arXiv, 1306.6516 | | Services: | Forum | Review | PDF | Favorites | |
