AbstractPlasma dynamics critically depends on density and temperature, thus well-controlled experimental realizations are essential benchmarks for theoretical models. The formation of an ultracold plasma can be triggered by ionizing a tunable number of atoms in a micrometer-sized volume of a 87Rb Bose-Einstein condensate (BEC) by a single femtosecond laser pulse. The large density combined with the low temperature of the BEC give rise to an initially strongly coupled plasma in a so far unexplored regime bridging ultracold neutral plasma and ionized nanoclusters. Here, we report on ultrafast cooling of electrons, trapped on orbital trajectories in the long-range Coulomb potential of the dense ionic core, with a cooling rate of 400 K ps−1. Furthermore, our experimental setup grants direct access to the electron temperature that relaxes from 5250 K to below 10 K in less than 500 ns.

Main Effects

Project of compact low energy proton storage ring (1.75 MeV) for production of high energy photons in reaction 13C(p,γ) 14N on internal target is presented. With the help of the photons it is possible to realize the scheme for detection of substances with heightened content of nitrogen using Nuclear Resonance Absorption method. Distinctive features of the construction are use of electron cooling method for beam heating compensation, and strong longitudinal magnetic field along full perimeter of the ring. For optimal work of electron cooling, compensation of space charge of the beam circulating in the ring is necessary. Results of simulation of main effects in the storage ring are shown. The results allow us to expect that proton current up to 100 mA can be stored and luminosity up to 3·1033 cm2 s -1 can be achieved
