MICAL consists of two main tasks:
1. Development of Instrumentation Prototypes for the European Solar Telescope, with two specific actions:
a) Demonstrator of the adaptive optics system of EST. This action consists in the acquisition of a set of elements that will form a complete optical wavefront correction system that simulates a system conceptually similar to that of the EST telescope.
b) Improvements for the GRIS spectrograph of the GREGOR telescope. This action is focused on providing the GREGOR telescope with a unique instrument, based on the improvement of the GRIS spectrograph, which can be considered as a prototype instrument designed for EST.
2. Auxiliary Infrastructure Improvements at the Roque de Los Muchachos Observatory (ORM). It is aimed at improving the basic infrastructures of the observatory, especially the facilities that are commonly used by the staff and workers of the user institutions.

The European Solar Telescope (EST) (http://www.est-east.eu) is a European solar physics initiative involving more than 30 institutions from 18 countries, under the coordination of the IAC, representing the largest infrastructure of European research projected in the field of solar physics from Earth.
