The preliminary assembly of the copper shell (PSS) executed during 2022 pointed out several critical issues, in particular the difficulty to keep the PSS on the temporary support frames with the shape close to the nominal one, making hard the installation of the 72 stiffening torlon rings. In order to guarantee the PSS shape close to the nominal position, a system of pushers to be installed on the temporary support frames has been proposed. This document describes the test of two proposals for the pushers (one 'commercial' and one 'custom') and the design of the selected solution ('custom') based on the results of the test.
