Finally, a Photo Stimulated Desorption beamline (PSD) is installed on the exit port of a dipole in the arc 8: it aims at qualifying narrow NEG coated chambers by measuring the dynamic pressure as a function of the photon dose. A first chamber of 63 mm diameter was already tested successfully before installing low diameter chamber (20, 10, and 6 mm) foreseen for the upgrade. FUNDING OF A NEW COOLING STATION AND THE EAST EXTENSION End of 2020, the construction of a new cooling station with its building was funded (12.7 M€) by the French economic recovery plan. This major project will make it possible to deal with the high obsolescence of the present cooling station and to achieve significant savings (water consumption reduced by 80%, and significant electricity savings thanks to environmentally friendly technology and energy-efficient equipment). The new station civil work will start early 2022 and be connected to the main technical infrastructures in the second part of 2024 while being compatible with the upgrade project of the accelerators and beamlines. 95
