Design concepts of a Cherenkov detector at the Facility for Rare Isotope Beams*

The mechanical design of a Cherenkov detector for the MoNA Collaboration scientific program at the Facility for Rare Isotope Beams is under study by the MoNA Collaboration. Such detector will complement the existing charged detector system to improve its particle identification capability as exotic ion beams will now reach relative velocities of b » 0.5. The Fusion360 software was used to optimize several configurations from triangular to hexagonal shapes to detect ions across a large area while minimizing losses between tiles. Hybrid devices that include diamond and semiconductors (Si and Ge), as well as single silicon carbide sheet were investigated. We will discuss the various designs including their advantages and deficiencies. This work was done in collaboration with CEMHTI (UPR 3079 CNRS) and Université d'Orléans in France.
