J Integrated systems testing – Milestone completed: SAR Gate 2 TRR 2022 -01 -03 PRESENTATION TITLE/FOOTER SAR 12

J Integrated systems testing – Milestone completed: SAR • SAR is the formal milestone for accepted Integrated systems Testing: • In SAR we look backward and forward as well. Backward: ü All integrated systems test results have been documented in a test report. ü Open items are identified in a punch list. ü NCR have been taken care of. ü In order to accept the integrated systems test report the corresponding V&V requirements must be fulfilled. ü This test report and its punch list has been reviewed and approved by Target Operation and Maintenance (TOM). Forward: ü Do we have all we need to enter Commissioning with beam phase? Documentation: All operation instructions, drawings, lists, etc. are updated with any modification done during the tes 2022 -01 -03 PRESENTATION TITLE/FOOTER 13

Critical connections between sub-elements N Electr, (5) TSS MPS (1) (2) (3) (4) Rough vacuum MCR (1) Should be tested together with MPS due to impact on Operational Limits and Conditions (OLC). (2) TSS has physical elements installed in the target systems, but shouldn’t impact on our testing period as they will test at the end. Coordination challenges. (3) Rough vacuum should be operational and available for Integrated system tests. Coordination challenges. (4) Main Control Room (MCR) functionalities should be available for integrated system tests. (5) Electr. , UPS & diesel back-up generator (e. g. circulators) 2020 -11 -25 PRESENTATION TITLE/FOOTER 14

J Critical path in P 6 PRESENTATION TITLE/FOOTER Nov-Dec

N Risks for the testing phases • Design not finalized and late design changes. Electrical LVPd in MUTS on hold, state machine Target wheel, etc. • Tight time schedule. Delay on design, manufacturing and installation will give limited time to prepare and plan tests due to personnel in parallel roles. • Young organization. Some routines and way of working must be adjusted during the test phase. • Operators and technicians for Target systems not on-board yet. • Lack of resources. Many test activities in parallel. Different systems ready for test at the same time. At the moment we are considering work time during the test phase is 8 h per day, 5 days a week; There is a risk this has to be increased. • Several one-in-a-kind components risk of unexpected test results or out of acceptance criteria. • Availability concerns during testing if severe fault on equipment as there are limited amount of spare parts available. • Project Coordination during testing phase between different projects is not in place yet (TSS, MPS). • Local Coordination during testing phase for activities in the same rooms between installation and test teams is not in place yet. • Clean zones both in the MUTS area and the connection cell as there could be other works in the surroundings. 2020 -11 -25 PRESENTATION TITLE/FOOTER 19
