Abstract
The hot electron generation by irradiation of intense
short laser pulses onto cone targets is studied by using 2D PIC simulation.
It is shown that the high energy electrons from the cone target are
characterized with three effective temprature, while two-temperature for
plane target. The electrons composing most energetic component are generated
at the cone tip where laser field is intensified by cone-guiding, and
electrons for middle component are generated at cone wing which is not
observed for plane target. The acceleration processes at cone wing, cone
tip, and rear surface are explained.
