Description
The installation of the SLS2.0 storage ring will start in October 2023. Most of the vacuum chambers composing the 288 m long storage ring will be made out of copper to dissipate the synchrotron radiation heat and to decrease resistive wall impedance. The nominal inner diameter is 18 mm with a wall thickness minimum of one millimeter and distance to pole going down to 0.2 mm at some locations. In the 7 bend achromats dipoles, the chambers will have an antechamber ending with a glidcop crotch absorber. The whole ring will be NEG coated to speed up the vacuum conditioning. Each arc is about 18 m long without any bellows so that NEG activation can be made in an oven outside tunnel. The installation of this long arc in the magnet apertures will be a delicate crane transport. This paper will describe the design and production of the different vacuum components as well as the first components tests.
