The APPA Cave

The plasma physics community will have access to a dedicated ion beamline in the APPA cave. The cave, whose layout is shown in the figure below, will be 1064 m2 large and its will be supplemented by the 650 m2 of the supply building. In addition to the plasma physics community, the cave hosts experiments from the SPARC and BIOMAT collaborations.

Overview of the APPA Cave

The plasma physics ion beamline

The 50 m long ion beamline is designed as a multi-use ion beamline to enable employing the proton microscope PRIOR and the other schemes proposed by the community like HIHEX and LAPLAS. The ion beamline location can be seen in the general cave scheme above, while a detailed view of the beamline is shown below. The ion beamline is made of the matching section, a free space to be used by the various schemes, the focusing magnets and the target chamber as depicted below.
