Science case

Main science drivers (comsic vision 2015-2025):

• Super Novae and the life cycle of matter

• Study of cluster evolution (physical state and chemical abundances) up to z=2

• Study birth and growth of supermassive BH at z~10

• Gravity in the strong field limit (relativisticaly broadened line)

• Matter under extreme conditions (near the surface of a NS)

Conclusions

• Science case

Need for 2nd cryogenic instrument optimized at low energies, energy resolution prime driver, then low energy cutoff (0.2-0.1), next countrate, and finally FoV

Redundancy is also an important driver

• Instrument development plan

Demonstrate capability to build cryogenic instrument for XEUS/Con-X in Europe

Concentrate on TES microcalorimeter (but not excluding others)

Next steps

• Science case: justification for 2nd instrument optimized at low energy Bleeker, Barcons

Compare to gratings, low E cut-off, Astro-E2,Be realistic, use cosmic vision

• Prototype instrument development plan de Korte + others• High level system overview, technology risks

and desired/required qualification level + technology risks

• Face-to-face meetings (where appropriate)• Funding (seek funding at national level)• Explore potential Japanese interest (ISAS)• Coordinate developments with ESA (payload

definition document etc)

• Identify consequences of magnetic micro calorimeter in the prototype

• Next meeting (spring 2005)

• Coordination/progress monitoring den Herder
