This completely new storage ring requires a new vacuum system including UHV chambers with complex shape and strict geometrical and dimensional tolerances. In order to meet these requirements we decided to build about half of the chambers in aluminum alloy machined from the bulk, the only technology permitting to respect the requirements. The result are 128 chambers, 2.5m long, built in alloy 2219 with Conflat flanges custom made from the chamber supplier by explosion bonding. The production phase is nearly finished, the produced chambers satisfy completely the expectations. A second generation of experimental aluminum chambers was designed as a substitution of some steel ones in order to solve same geometrical difficulties. These chambers are very complex as they have steel-aluminum junctions in the body in order to accommodate bellows and beam position monitor buttons. The delivery of the first prototype of this type of chamber is previewed for June 2018.
