Summary of actions

Notes from IPAC19

by Christopher Hunt

Due 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.

Found 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.

ELI:

  • Prague institute
  • Expect first beams by the end of the year
  • 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
  • Conventional focussing
  • Use a reasonably big laser with plans to upgrade in the next few years (>1 Petawatt)

CLAPA:

  • Peking University
  • Publicized results already,
  • Very large laser (I think Petawatt class), with planned upgrades
  • Uses conventional focussing, maybe quadrupole capture,
  • Claim very high stability and high energy beams
  • Really seem like they are ahead in the game

Observed some comments on polarised beams to improve performance of laser-target interactions - not sure what the logic is?

General 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.

There were no mentions of high-current proton cyclotrons that I could find

I found one poster discussing a flash-dose electron cyclotron,

Found 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.

Couple of 200+MeV proton cyclotrons in the works, but these are low-current machines
