  1. B1 Summary: How do the ion sources and injectors presented at RPIA 2006 compare? What are their prospects? Group: J. Barnard (convener), R. Briggs, J. Hasegawa, K. Horioka, T. Iwashita, S. Kawata, S. Lund, Y. Oguri, G. Westenskow, + ...

  2. RPIA 2006 had two talks on injectors/ion sources for heavy ion fusion/hedp. How do they compare? What are prospects for laser sources? Possibility of Laser Ablation Plasma as High Flux Ion Source for Induction Accelerators, M. Nakajima and K. Horioka (TIT) Hot plate source using laser to heat hot plate, G. Westenskow and J. Kwan (VNL) Multibeamlet injector, G. Westenskow, D.P. Grote, J.W. Kwan, F. M Bieiniosek (VNL)

  3. Comparison of parameters

  4. Check list of issues for ion sources for WDM (adapted from Joe Kwan/Glenn Westenskow)

  5. Experimental setup (fromM. Nakajima and K. Horioka (TIT)

  6. Conclusion: Laser ablation source may be good match to NDCX-II accelerator requirements for WDM studies Requirements: Total charge: 0.1 mC Pulse duration: 100 ns Rise time: ~10 ns Low normalized emittance, low longitudinal emittance Main issues: Longitudinal emittance ? Matching beam into low energy transport region (large space charge, conververging beam? Charge state purity? Contaminants?
