European Solar Telescope

The EST design will strongly emphasise the use of a large number of visible and near-infrared instruments simultaneously, thereby improving photon efficiency and diagnostic capabilities relative to other existing or proposed ground-based or space-borne solar telescopes. In May 2011 EST was at the end of its conceptual design study.

The EST is being developed by the European Association for Solar Telescopes (EAST), which was set up to ensure the continuation of solar physics within the European community. Its main goal is to develop, construct and operate the EST. The European Solar Telescope is often regarded as the counterpart of the American Daniel K. Inouye Solar Telescope which finished construction in November 2021.

Conceptual design study

The conceptual design study conducted by research institutions and industrial companies was finalized in May 2011. The study took 3 years, cost €7 million and was co-financed by the European Commission under the EU's Seventh Framework Programme for Research (FP7). The study estimates a €150 million to design and construct the EST and projects about €6.5 million annually for its operation.
