Science Advisory Group

The Science Advisory Group (SAG) is a group of experts consisting of senior scientists. One task of the SAG consists in analysing the final scientific requirements for EST.

Building on the existing EST Conceptual Design, and the prioritised scientific goals (and technical updates), SAG's main task is to refine the EST concept by analysing the present version of the scientific requirements of the solar community taking into account the technologies likely to be affordable over the next decade. SAG outcome will provide more precise estimates of the capabilities of EST to address key science issues (through benchmark studies), and ensure that EST provides the expected significant scientific advancement beyond the current state-of-the-art in the field. The progress and completion of this task will lead to the final Science Requirement Document SRD (physics key problems discussed, final expected EST response).

The current version of the Science Requirement Document (SRD) was presented to the international community during the first "EST Science Meeting" held at Giardini Naxos (Sicily), from 11-16 June . The SAG is currently analysing the main conclusions reached during the meeting.

The SRD will be the base for the Technical Requirement Document (TRD). The TRD sets the constraints and specification for the final design of EST.


The EST science cases and their corresponding Observing Programs (OPs) are structured in 9 sub-groups:

SG1: Structure and evolution of magnetic flux

SG2: Wave coupling throughout solar atmosphere

SG3: Chromospheric dynamics, magnetism and heating

SG4: Large scale magnetic structures: sunspots, prominences and filaments

SG5: Coronal Science

SG6: Solar Flares and Eruptive Events

SG7: Coupling in partially ionized solar plasma

SG8: Atomic physics and Hanle-Zeeman diagnostics 

SG9: Nasmyth focus science
