European Solar Telescope – The Science Requirement Document update for the Call for Science Cases

September 15, 2018, from Richard Morton

The European Solar Telescope (EST: is a next generation large-aperture solar telescope. This 4-metre telescope will be optimised for studies of the magnetic coupling between the deep photosphere and upper chromosphere. The Science Advisory Group (SAG: of EST is presently updating the Science Requirement Document (SRD). The old document dates back to 2010. During the ongoing EST Preparatory Phase, the full (optical, mechanical, thermal, and instruments…) design, and hence the technical requirements, need to be finalised. For that purpose the SRD is revisited and adapted to recent scientific and technological developments.

The SAG has drafted a first version of this update (cf. SAG webpage). With this call, we aim to collect top-level science cases from the solar community:

More information is provided at the latter webpage. The SRD update is divided into 9 scientific sections. Direct your input either to the chair of the corresponding subgroup or to the chair of the SAG.

The input deadline is set for October 30, 2018.
