The purpose of the CORSIKA 8 Focus Week is to connect CORSIKA 8 developers and interested enthusiasts for a sequence of days, each day, with a flexible agenda. Please send proposals to be discussed or points for the agenda, otherwise we decide dynamically with ~one day advance what are the most important points.

It is of course optimal if a sufficient number of people actually pledges to do significant work on CORSIKA 8 development during this period of time, so that each day we can shift our topics/focus given the ongoing discussions on gitlab.ikp.kit.edu.

        Discussion

        Welcome to the 2nd CORSIKA 8 Focus Week

        The aim is to make a major concerted step toward the next milestone release "Physics demonstrator (hadron core)", which should become the foundation of what we want to show at ICRC 2019. We should have a final milestone release in ~May/June to identify the actual version of CORSIKA 8 used for ICRC 2019.

        Today we should set our priorities for the coming week and also for the upcoming milestone.

        We should try to focus on physics aspects, including first validation and comparisons to CORSIKAv7. Only critical technical aspect should be addressed now if they are needed for physics.

        Discussion

        We need at least one low-energy hadron interaction model. Could be GHEISHA or URQMD (good for comparisons to CORSIKAv7) or HillasSplitting (comparing to AIRES).

        We need to test and finalize the mechanics to switch between high/low energy models for given projectile particles.

      Not open meeting on licensing and considerations

      Session together with legal experts from KIT to discuss options and issues with licensing choices, and related agreements. Relevant results and conclusions of this meeting will be be discussed with everybody in the corsika project.

      No direct or firm conclusions from this interesting meeting. Here is what we could do from our side

      - GPL, if supported (enforced) by KIT --> check

      - Need to still formulate collaboration agreement or MoU that is good for all of us.

      We should discuss this until and at our June workshop.

        Discussion

        We need energy losses and multiple scattering for hadrons and muons.

        We will work on this milstone until we manage to get a direct comparison between CORSIKA7 and CORSIKA8 which we are able to understand. The phase space for this comparison should be

        - No magnetic field, B=0T

        - In air

        - Exponential density profile, need to clarify if 1 layer or 5 layers, both possible.

        - switch off Electron/gamma in CORSIKA7

        - Only hadrons+muons

        - use 80GeV cutoff energy for hadron, muons (and electrons)

        - SIBYLL 2.3c

        - start with vertical showers, proton... iron, several energies, maybe ~100 shower samples

        - compare particles on observation level, e.g. 1400m (?) any number is ok...

        - compare longitudinal dEdX for hadrons and muons

        Stack infrastructure

        Status of particle stack infrastructure. There are many ways where we need to access the stack and stack data, which is not yet fully implemented and designed.
        In this context we may also talk about the Cascade workflow and the best way to define "stack view" and "full stack" analysis processes etc.
