Beschreibung

The workshop is organized by the LIGHT collaboration and focuses on the beam shaping of laser-driven ion beams. The main topics are:

I. recent progress within the LIGHT collaboration
II. defining the next milestones for the collaboration beyond 2015
III. international cooperation possibilities

The workshop will start Monday, January 12th, at 01:00 PM and will end on Tuesday, January 13th, around afternoon. There will be several sessions for talks and discussions as well as a dinner on Monday evening.

The current timetable (and contribution list) is preliminary and will be subject to changes.

Registration please via the form on this page. Application for a talk is possible within the registration form, too. (If you have an indico account, you may first log in and then use it for the registration process.)

Recommended accommodation possibilities for external paticipants are:
- GSI guesthouse (on-site, please refer to the LIGHT collaboration meeting [plasma physics department; contact: Simon Busold])
- Hotel Weißer Schwan (Arheilgen, 3.7km, public transport available)

    Target Fabrication at TUD
    
    The Detector & Target Laboratory at the TUD-Institute for Nuclear Physics is a small scale university facility with its focus on the development of manufacturing techniques for targets used in particle and laser beam experiments. This presentation informs on our characterization and manufacturing capabilities with respect to target specifications achievable, possible geometries, tolerances and material combinations. We both produce for in-house experiments and supply targets for experiments at key laser and accelerator facilities world wide.

    The Current LIGHT Beamline at Z6
    
    The experimental parameters and results are presented in detail: The available laser parameters from the PHELIX 100 TW laser beamline, the accessible proton beam parameters from the TNSA source at Z6, the applied ion optics for energy selection and beam transport and the installed radio-frequency cavity. Two operational modes have been demonstrated successfully for protons in the range of 10 MeV energy: 1. energy compression of the bunch to <3% energy spread and 2. phase focusing to a pulse length <500ps, in both cases with about 10^9 protons in a single short bunch.

    Post-acceleration of laser generated protons by a high gradient CH-cavity
    
    The linac activities are aimed to increase the accelerating field gradient. A high gradient CH – cavity operated at 325 MHz was developed at IAP – Frankfurt. The accelerating field gradient is expected to reach > 10 MV/m. Within a funded project, this cavity will be further developed towards a high gradient cavity. The new GSI 3 MW Thales klystron test stand will be used for the cavity RF power tests. The results will influence the rebuilt of the Unilac - Alvarez section, aiming to optimize and achieve finally the beam intensities specified for the GSI-FAIR project. Another option for this cavity, it might be used to post-accelerate a proton bunch, generated by an intense laser, from 10 – 16 MeV.

    Pulsed power technology in the field of laser-plasma physics - Status update 2014
    
    The presented work will summarize the development of pulsed high-field magnets and power converter technology at HZDR in 2014 for application in laser-plasma physics. The talk will focus on miniature magnetic solenoids, pulsed multipole magnets and the generation of high-current pulses.

    Optimum parameters for Radiation Pressure Acceleration
    
    This work faces on the optimization of the RPA beam quality in dependence of the laser and target parameters: - A relativistic two fluid model of the laser plasma interaction is derived. From this analytical model, two important perceptions will be obtained: 1) An approximation to the maximum achievable kinetic energy. Within this, a termination criterion for the RPA mechanism is achieved, above which the acceleration process collapses. 2)The optimization of the RPA: An analytical prediction is supported by a 1D PIC simulation, to work out the optimum working point for the acceleration process.

    The UK A-Sail Ion acceleration collaboration
    
    A UK grant funded consortium was formed in 2013 to further research into laser driven ion accelerators for potential medical applications. The consortium which consists of Queens University, The University of Strathclyde, Imperial College London and the Rutherford Appleton Laboratory will coordinate developments in this area. I will report on our efforts to improve the understanding of ion acceleration at high intensities and deliver better beam stability and the development of new cryo target capability and ion beam diagnostics which can operate at high repetition rates. I will present an overview of our work in the first year of this grant and our plans for the future years.
