CERN situation S Gilardoni ENSTI For good news

CERN situation* S. Gilardoni – EN/STI * For good news please refer to Daniela’s and Oliver’s presentations 1

Where we are: Long Shutdown 2 (LS 2) • Perform major Maintenance and Consolidations • Increase intensity/brightness in the injectors to match HLLHC requirements (LIU Project) Implications for n_TOF • Increase injector reliability and lifetime to cover HL-LHC run (until ~2035) closely related to consolidation programs (in synergy with LIU Project) • Anticipate HL-LHC work LS 2 LS 3 03/10/19 S.

LS 2 Version 2. 2 (official CERN schedule) ISOLDE still to be approved Everything so far according to plan (see Daniela’s and Oliver’s talks) 03/10/19 S. Gilardoni - n_TOF collaboration board 3

EN structure for n_TOF Two CERN groups involved Group Leader: S. Gilardoni Deputy GL: M. Calviani Main activities: ISOLDE, FLUKA, secondary particle production targets, beam intercepting devices, lasers, n_TOF, UA 9, R 2 E Group Leader: A. Masi Deputy GL: H. Mainaud Durand Main activities: Survey, Mechatronics, Robotics, control software and systems, n_TOF support, Labview, R 2 E, UA 9 support. CERN responsibility for running the facility shared between EN/STI and EN/SMM: Everything which is not DAQ, acquisition/control systems and alike lies in EN/STI. CERN n_TOF budget under EN//STI responsibility. 03/10/19 S. Gilardoni - n_TOF collaboration board 4

Comments on CERN/groups financial situation (I/II) • CERN general critical financial situation until ~ 2025 • • • Significant reduction of CERN budgets starting in 2020 (up to 20% in some cases) including n_TOF Final budget reduction still to be defined precisely Consequences for n_TOF at the groups level, refocusing resources to secure best facility operation possible: • • • Reduction of funding for non-CERN personnel (PJAS and others, for example manpower for data processing) and conference/workshop participation funded by EN operational budgets. Will keep funding to secure future Ph. D students and their training. This discussion does not includes Research Fellow and Research Associate covered by another funding line. Current EN CERN staff man-power dedicated to n_TOF will remain. Need to review with collaboration funding lines for long-term support of part of infrastructure (any new request for HW for DAQ for example) and support during running period (24/24 on-call services). Seeing with EN/SMM how to cope with future needs and secure best support possible during running periods. 03/10/19 S. Gilardoni - n_TOF collaboration board 5

Comments on CERN/groups financial situation (II/II) • Budget for completing new target in the current configuration already secured including commissioning budget and man-power Only very minor design changes to targets can be still accommodated if necessary. Cost-to-completion already frozen. Other works (like full implementation of NEAR as irradiation station) cannot be funded by CERN budgets • • • Interventions mentioned by Oliver presentation funding secured if no further budgets reduction • • • Cost-to-completion already frozen for movable shielding, partially funded by other project Modification of the movable shielding and port-holes will be executed before end 2020 Plan B is to delay some of them in 2021 if necessary Revise with collaboration spending profiles to solve cash flow issues. Budgets for completing infrastructure consolidation under scrutiny • • • Detector testing laboratory completed Control room displacement final implementation to be quoted Modification following recommendations from CERN External Safety Authorities. 03/10/19 S.

Comments on facility medium/long-term prospects • Target as main cost driver for facility consolidation • • Any other facility modification request has to be planned years in advance • • Current target planned life time: 10 years Next planned target exchange in LS 4 (>2028) Should start thinking about new target probably around 2024 -2025 Group/Project Budgets already assigned up to 2023 No CERN funding available in short/medium-term to finance NEAR with fully remote sample manipulation (e. g. remote delivery system and its infrastructure) • • • Dedicated moderator under study Provided funding available, further modifications could take place during a YETS or EYETS (Extended Yearly Technical Stop in winter) depending on dose rate after a short decay time and depending of geometry chosen or during an LS. Today limited man-power available focused now on facility core activities 03/10/19 S. Gilardoni - n_TOF collaboration board 7

Conclusions • Strong CERN commitment to continue to support n_TOF operation in the future years and be part of the collaboration • • Discussion to find the best configuration together with current and future spokesperson for budgets related issues n_TOF is using 25% of the total number of protons produced at CERN (~ x 10 more than the LHC) • • • Availability has to be maintained the highest possible Addition of NEAR irradiation station will even improve the efficiency in use of these protons Unique facility, doing our best to keep it even more unique 03/10/19 S.
