2. Florence CMB Coordination Mtg - Mohr
Concept
Contribute next generation 6m wide field survey telescope to the SPT Collaboration
Seek German DFG funding at 12MEUR level for new telescope in return for broadened German participation in SPT
Further CMB-S4 through near term prototyping and (ideally) with ready-made LAT at South Pole
5m diameter / 100 deg2 FOV
136k Fl pixels at 150GHz

Motivations
Structure formation science with SZE and CMB lensing
Galaxy cluster physics
Feedback and impact on matter power spectrum
Galaxy cluster cosmology
SPT surveys + auxiliary data already rich resource
Scientific advances in cosmology, cluster studies, dusty galaxy and AGN studies
Multi-l sky surveys will provide new science leverage
SPT
MeerKAT

Funding Status
DFG interested in concept, but broad participation needed
Currently Astrophysics/Cosmology Chairs at six German universities have expressed interest/support
LMU-Munich, Heidelberg, Bonn, Aachen, Hamburg and Bielefeld
Interest also within MPG (MPA and MPIfR), raising possibility of cost sharing between DFG and MPG
With go-ahead from DFG we expect to submit a proposal this fall

5. European Coordination and CMB-S4
Collaboration on populating the focal plane an obvious possibility
Implications for low frequency LAT surveys?
See talks by José-Alberto Rubiño Martin and Angela Taylor tomorrow
Flesh out design/construction/operations details on a monolithic mirror, wide field concept that offers advantages for polarization studies
