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.
The plasma physics ion beamline
The 50 m long ion beamline is designed as a multi-use ion beamline to should 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.
Work packages
The work packages follow the FAIR nomenclature and concern sub-systems of the beamline installation. Below is a list of the plasma physics technical work packages. The work packages are described by technical design reports written by the collaboration and approved by the FAIR Expert Committee Experiments (ECE).
