Abstract

Numerical estimates for pair production from vacuum in the presence of strong electromagnetic fields are derived, for two experimental schemes : the First concerns a laser based X-FEL and the other imitates the E144 experiment. The approximation adopted in this work is that of two level multiphoton on resonance. Utilizing achievable values of laser beam parameters, an enhancedproduction efficiency of up to 10^11 and 10^15 pairs can be obtained, for the two schemes respectively., Comment: 6 pages, 4 figures

Abstract

International audience; A novel scheme and methodology for the production, acceleration and extraction of ions, both negative and positive, for a broad spectrum of applications is investigated. The production of the plasma, from which the ions are extracted, is based on ultra-short high intensity laser beam interaction with clusters. The non-linear propagation and filamentation effects during the propagation of the ultra-short laser pulse in the clusters improve the volume ion production [1]. The selection of negative or positive ions extraction from the plasma is based on the magnetic insulation principle, where a strong external magnetic field is coupled to an accelerating electric field in a diode-like configuration [2]. The main advantages of the proposed ion source are (a) the high density of the produced ion beam and (b) the relatively small volume of production. A multi-fluid code in cylindrical geometry describes the spatio-temporal evolution of plasma species in the magnetically insulated diode configuration [3]. The code is also used to calculate the evolution of the state parameters of the plasma produced from filamentation [1]. These results enable us to investigate an improved configuration for plasma generation based on filamentation effects in (i) compact magnetic fusion devices and (ii) important applications of negative ion beams for plasma heating. The new high energy, high average power, high efficiency ICAN fiber laser [4] is a good candidate for both the plasma generation and the photoneutralization of negative ions beam. [1] Moustaizis, S.

Abstract

We present experimental results concerning the observation and acceleration of negative and positive ions produced from high-intensity laser beam interactions with deuterated and hydrogenated clusters. The 30-fs, 10-Hz rep. rate, 30 TW Ti-Sa laser of LOA was focused on clusters produced from a pulsed gas nozzle. The novelty of our experimental work was the gas composition (CD4 and CH4), which was used for the cluster formation. Both kinds of ions, negative and positive, were observed with approximately equal energies. The maximum energy of both kinds of ions as well their energy distribution was measured using a Thomson parabola mass spectrometer. Negative and positive ions of H, D, and C were observed with a maximum energy up to 70 keV for a maximum laser beam intensity of 10[sup 18] W/cm². The mass spectrometer allowed us to correlate both the positive and negative ion energy spectrums with the laser beam intensity in order to study the process of cluster explosions, ion acceleration, and negative ion formation in the fs regime. We summarize the more important and new results as follows: (1) only single positive and negative ions were measured on the mass spectrometer; (2) the number of negative ions is equal to the number of positive ions; (3) similar energy spectrums for positive and negative ions were measured; (4) the positive and the negative ions are accelerated in the same radial direction, outwards from the interaction volume; and (5) similar energy spectrums for positive and negative ions at different laser energies (the laser intensity increases by a factor of 5) were measured. There are two possible "scenarios" concerning the process of negative ion formation. The first process is related with the formation of different ion species during the Coulomb explosion of the clusters. The second process for negative ion formation is the double electron attachment caused by collisions between the positive ions with the backing gas. A number of... [ABSTRACT FROM AUTHOR]

34. Towards a laser neutron driver.

Abstract

During the last few years, important experimental investigations have been made concerning the possibility of induced nuclear fission of high-Z elements by electromagnetic interaction (photofission, electron fission, neutron fission). Fast ions, neutrons and fission fragments from such interactions can be used to pump a laser medium, to produce energy from the (232)Th-(233)U nuclear fission cycle. The main aim of the present work is to study a three-step process, in a relatively new experimental scheme, in order to improve the number of both neutrons and fast ions. In the proposed scheme, high-energy particles and photons are produced by high-intensity laser beam interaction with a solid or gas target, which are utilized later on to trigger the nuclear reactions for the production of (photo) neutrons. These neutrons can give rise to fission of (232)Th that leads through a cascade of decays to (233)U --a highly fissionable material. Such a process will enhance, by an important factor, the final neutron flux and the energetic fission fragments. The use of a high intensity pulsed laser beam will control the turn-on and turn-off of the nuclear reactions and allow one to ensure the security of the whole operation. Finally, the produced neutrons are used to accomplish a major population inversion in an appropriate gas medium for the last stage of amplification of a high-contrast ultra-short laser seed pulse.
