ERR

• The first ERR was done
• Discussion for reactions to the ERR report
  • Radiation calculations will be done by Tokyo group by using FULKA and Geant4.
    → Sho installed FULKA in his laptop, and obtained a sample code for HKS from Pavel.
    → Sho will share the FULKA code with us, and Guido will work on it as well.
    → At first, we are going to ask Pavel to create the first code based on the latest design.
