meeting, organised in the framework of this task, addressing the pan-European positioning of
European Radio Astronomy for SKA. The current report addresses additional coordination actions
undertaken by ASTRONET, and focuses on challenges of common interest to all facilities (Chapter
3), and the continuation of the discussion on the organisation of Radio Astronomy in Europe for the
SKA (Chapter 4).

Square Kilometre Array (SKA) are considered the two flagships for ground-based astronomy. These
two projects emerged as clear and equal top priorities, with the E-ELT being more mature in its regarding coordination of large
governance and technological readiness, and planned to be realised before the SKA. Three high
priority projects have been identified in the medium scale category: the Cherenkov Telescope Array
infrastructure projects
(CTA), the European Solar Telescope (EST), and the Cubic Kilometre Neutrino Telescope (KM3NeT).
The ASTRONET Roadmap also lists several large space missions as high-priority projects. The
EU Astronet
Advanced Telescope for High ENergy Astrophysics (ATHENA+, formerly known as XEUS/IXO) and

the New Gravitational wave Observatory (eLISA, formerly called NGO and LISA) were both ranked
as the top priorities. Next in priority were two missions Appraisal

CTA Main Science Theme Cosmic Particle Acceleration – How and where are particles accelerated? – How do they propagate? – What is their impact on the environment?
CTA Main Science Theme Probing Extreme Environments – Processes close to neutron stars and black holes – Processes in relativistic jets, winds and explosions – Exploring cosmic voids
CTA Main Science Theme Physics frontiers: beyond the Standard Model – What is the nature of Dark Matter? – How is it distributed? – Is the speed of light a constant for HE photons? – Do axion-like particles exist? CDM implications?

Cleaning Coating
Exact cleaning and recoating protocol depends on local regulations. Peoplepower is the dominating cost factor. More
automation is key. The current design of the coating facility can process 8 MST mirrors per day using < 1 FTE.cherenkov
