9 LUNCH BREAK

10 Discussion

What do we want to learn form the W HCal prototype ? Slow neutrons and E-resolution, PFA, time-stamping What simulations are still needed ? At what beam energies shall we test the prototype ? List of priorities What minimum size (lateral and longitudinal) is needed ? Any constraints to equip CALICE module with W plates ? Which active layers to be used, and when ? What granularity of the active layers for the prototype ? Tracking upstream of the prototype Readout and DAQ Possible schedule Action list

Speaker: un-moderated, participation by all

11 END OF PLENARY SESSION

12 Discussion Round on Engineering Issues
