Title:
Physical Results Derived From a Possible Analogy Between Laboratory Laser Plasma Acceleration And Cosmological GRBs Explosions
Date: Wednesday, April 5th, 2006
Time: 12:00 noon
Venue: Villa Bazzoni

Abstract:
GRBs are cosmological explosions characterized
by the most spectacular power surface density emitted in any `cosmic
phenomenon . This special cosmological Fire Work, lasting few seconds,
outshine by one order of magnitude the total gamma flux in the energy
range of few hundred kev, emitted by all Universe reaching the top of
our atmosphere . Among the most power full man made devices the Lasers
of very short pulses can concentrate enormous power surface density on
a gas target .In the seminar the preliminary consequences derived by
the analogy between the two phenomena GRBs and Laser plasma
acceleration are considered together with the proper scaling from the
laboratory experiment to the physical environment around the GRBs
engine.
