     56Due to clashes, issues with the papers etc, I didn't manage to attend a lot in person, however these are some observations from what was available and a few conversation.
     57
     58Found two of the biggest players, ELI and CLAPA (its likely that I missed some of the other big names). Both have similar ideas: laser-target produced protons with some conventional magnet based capture and delivery system, both targeting radiobiological research.
     59
     60ELI:
     61* Prague institute
     62* Expect first beams by the end of the year
     63* They have designs for a cryogenic H2 target, basically extruding liquid hydrogen into the target area. It wasn't obvious how advanced the designs were
     64* Conventional focussing
     65* Use a reasonably big laser with plans to upgrade in the next few years (>1 Petawatt)
     66
     67CLAPA:
     68* Peking University
     69* Publicized results already,
     70* Very large laser (I think Petawatt class), with planned upgrades
     71* Uses conventional focussing, maybe quadrupole capture,
     72* Claim very high stability and high energy beams
     73* Really seem like they are ahead in the game
     74
     75Observed some comments on polarised beams to improve performance of laser-target interactions - not sure what the logic is?
     76
     77General consensus is to just use a bigger laser and conventional capture/focussing. I got the impression that shop-bought petawatt-class laser was the starting point for several groups.
     78
     79There were no mentions of high-current proton cyclotrons that I could find
     80
     81I found one poster discussing a flash-dose electron cyclotron,
     82
     83Found rapid-cycling synchrotron design with reasonable footprint (20mx10m) producing 250MeV beam. Due to the size of laser systems, this is probably the same footprint as a laser-target facility.
     84
     85Couple of 200+MeV proton cyclotrons in the works, but these are low-current machines
