DAΦNE GENERAL CONSOLIDA TION AND UPGRADE

In the first six months of 2013 the KLOE detector has been upgraded inserting new layers in the inner part of the apparatus, around t h e i n t e r a c t i o n r e g i o n . T h e l o n g shutdown has been used to implement a g e n e r a l consolidation program aimed at improving the Φ-Factory operation stability and reliability and, in turn, the collider uptime. In this context several systems have been revised and upgraded, new diagnostic elements have been installed, some critical components have been modified and the interaction region mechanical support structure has been redesigned to improve its mechanical stability and to deal with the weight added by the new detector layers.
