“…Its magnetic field is azimuthally directed and radially linearly increasing. This field focuses a parallel beam onto a spot [1][2][3][4][5][6] or, vice versa, a divergent beam from a production target into a parallel beam [7][8][9][10].…”

A specifically tailored plasma lens could shape a high-energy, heavy-ion beam into the form of a hollow cylinder without loss of beam intensity. It has been experimentally confirmed that both a positive as well as a negative radial gradient of the current density in the active plasma lens can be the underlying principle. Calculations were performed that yield the ideal current density distribution for both cases. A numerical simulation of an experiment with an intense ion beam highlights that the shaping of the beam increases the achievable compression in a lead sample.

“…To accurately align the first and second stages, we made use of the focusing, azimuthal B-field generated by the discharge current. The discharge capillary acts as an active plasma lens [15,16]. Solving the equation of motion for this problem shows that a discharge current of 60 A applied over the 33 mm length of our capillary is sufficient to collimate a 100 MeV electron beam with an initial divergence of 3 mrad if a laser beam dump foil of 15 µm thickness is in the electron beam path.…”

Abstract. We present initial experiments on staging of two separately driven laser plasma accelerators (LPAs) towards high energy physics and beam deceleration experiments. A study establishing long term stability of electron beams accelerated by an LPA in density downramp configuration [1] is presented, demonstrating the appropriateness of these beams as an injector for staged acceleration. Subsequently, these injector beams are used to longitudinally probe the fully characterized wakefield [2] excited in a discharge-capillary-based second stage accelerator.

The progress of the experimental research program at GSI for studying beam-plasma interaction phenomena is reported. Heavy-ion beams from the new accelerator facility SIS/ESR at GSI-Darmstadt are now available for experiments, and will soon deliver > 10 9 particles per pulse in 100 ns. Focused on a small sample of matter, the beams will be able to produce a high-density plasma and to permit investigation of interaction processes of heavy ions with hot ionized matter.For the intense beam from the new heavy-ion synchrotron (SIS), a fine-focus system has been designed to produce a high specific deposition power beam for target experiments with a beam-spot radius of 100 ftm. We further discuss improvements of this lens system by nonconventional focusing devices such as plasma lenses.Intense-beam experiments at the RFQ Maxilac accelerator at GSI have already produced the first heavy-ion-induced plasma with a temperature of 0.75 eV. New diagnostic techniques for investigating ion-beam-induced plasmas are presented. The low-intensity beam from the GSI UNILAC has been used to measure energy deposition profiles of heavy ions in hot ionized matter. In this experiment an enhancement of the stopping power for heavy ions was observed. The current experimental research program tests basic plasma theory and addresses key issues of inertial confinement fusion driven by intense heavy-ion beams.
