1. WP9 updated Upgrade of SPARC test facility for high gradient acceleration of electron beams for SuperB collider and FEL projects WP number9Start month1End month36 WP TitleHGA (High Gradient Acceleration) Activity TypeRTD Objective Upgrade of SPARC Test Facility for High Gradient Acceleration studies of electron beams for SuperB and FEL projects Participant number78 INFNPSI Person-months 67  5428  24 20% cut 15% cut

2. Changes after budget cut One Subtask (9.1.1) cancelled: “design and construction of a SLED (pulse compressor)” Cut of Milestone 9.2 (SLED design) PSI will keep their Task on RF-LLE but implementation at SPARC will be performed by INFN personnel Keeping sub-contract with Rome University for 30 keuro  re-scoping their contribution with RF bench measurements and simulation of wake fields in accelerating structures New travel rate (650 euro/travel) Consequence of budget cut: lower final energy due to SLED cut (possible implementation after TIARA with other funds). This will not have impact on the main scope of the WP that is the test of the C-band Linac
