Decisions taken at this meeting:

1) The HCAL barrel absorber material for the new CLIC detector model is steel. (Further optimisation might lead to a reduced outer radius of the HCAL barrel - e.g. one might be able to have fewer layers keeping the overall depth of the calorimeter).

2) The solenoid magnetic field for the new CLIC detector model is 4 T. (It was mentioned that the aspect ratio of the solenoid is not favourable to achieve a homogeneous field - making the solenoid a bit longer would not be a huge technical issue. Conflicts with other design ingredients (related to the L*) might however appear.
