The CORSIKA 8 air shower simulation framework — •Alexander Sandrock for the CORSIKA 8 collaboration — Bergische Universität Wuppertal, Gaußstr. 20, 42119 Wuppertal

Originally developed for the KASCADE experiment, the air shower simulation code CORSIKA is now used in the simulation chain of numerous experiments in astroparticle physics. The monolithic hand-optimized Fortran code, that has served the community for the last decades, becomes increasingly difficult to maintain and to expand. For this reason, a community effort has been started in 2018 to rewrite CORSIKA as a flexible air shower simulation framework, making use of the possibilities of modern C++ standards.

By now, CORSIKA 8 is capable of simulating both hadronic and electromagnetic components of an air shower, calculate the radio and Cherenkov emission, and offers a considerably increased flexibility in defining properties and geometries of the media, in which the shower is to take place. Several abilities already go beyond what is possible in earlier versions of CORSIKA, such as cross-media showers or full genealogy of particles.

This presentation discusses the status of the implementation and validation of this new air shower simulation framework.
