Actions List 1

ACTION LIST BEER • Revisit current plans for access policies • ESS will try to accommodate the policies from ILL and ISIS • Process under consideration but nor real actions taken • Industry is more and more involved (separate or group visits and workshops) • Details on flux under different pulse shaping modes and explain the functionality • Day-1 no high flux option in pulse shaping mode – variation from high to medium resolution • Modulation technique available from Day-1 with various resolution – limited multiplication factor • Source: 2023 – 250 -600 k. W, 2024 (SOUP) – 700 -1300 k. W, 2 MW at Q 4/2025 2

ACTION LIST BEER • Capabilities of sample environments for BEER • Deformation rig and dilatometer are main focus from the instrument team – more suitable for science research • Gleeble is more industry oriented simulator • Contact with industry and Dynamic Systems to understand the needs in progress • Determine what types of alignment hardware and strategies are required, e. g. by discussion with instrument teams at other neutron stress scanners. • Development of the alignment tool by Malcolm continue • Discussion with SMARTS team was carried out • Further active contact with other engineering instruments in near future • Adopt project planning software • Done both HZG and NPI planners use the MS Project software 3

GUIDE OUTSIDE OF THE BUNKER Contract for the transport guide and guide exchanger • Contract for the design and manufacturing of the transport guide (outside of the bunker, including safety shutter part) + focusing part (including slit system) + guide exchanger was signed – Nuvia-Mirrotron is the winner • Kick-off meeting in January • Early manufacturing documentation will be submitted shortly for transport part • IDR planned in September • Discussion on the last slit system design: fixed exchangeable apertures vs. motorised slit system (limited space) 9

IDR – CAVE, GUIDE SHIELDING, SAFETY SHUTTER IDR meeting in December 11, 2018 • Small issues with the level of description of interfaces • Safety shutter needs some more work • Overall no mayor issues with the concept design • Serious debate about the H 1 and H 2 scenarios for engineering • Definition of “full beam”, redefinition of “worst-sample” • Passive shielding for H 2 preferred • Not-real comments about shielding calculations • Cave re-design 10

H 1 AND H 2 SCENARIOS Full beam and the worst-sample definition H 1 IDR definition Full beam: all choppers stopped open, all slits are fully open Worst-samples: 1 cm 3 of water (neutron scatterer), 1 cm 3 Ni (gamma emitter) H 2 IDR definition (active monitoring, dose on cave wall 20 m. Sv/h) Full beam: all choppers stopped open, all slits are fully open Worst-sample: 100 x 1 mm 3 Cd sheet Cave wall thickness in IDR: 55 cm rear and side walls, 60 roof and front wall Re-definition of the worst-sample: 4 x 4 x 1. 5 cm 3 on Ni (Ni harder gamma than Cd) Active monitoring of H 2: troubles with definition of devices and place where to measure, safety components! – expensive, passive solution preferred when reachable New simulation shows that H 1 (bigger Ni) overgoes H 2 (Cd in the beam) Thicker shielding needed -> front and roof wall 125 cm, side and back wall 105 cm !Shrinking of the inner space, floor load capacity, feasibility! Þ re-definition of roof as control-zone (25 m. Sv/h – no access), walls: concrete + steel Þ Side and rear wall: 60 cm concrete + 14 steel, roof: 78 cm of concrete (B 4 C tiles on walls) Þ Floor load: 20 t/m 2 very difficult to achieve – local overload could be acceptable Þ Schedule delay: 2 months (but we could keep the installation at the end of this year) 11

H 1 AND H 2 SCENARIOS Full beam and the worst-sample definition What if floor load limit will be able to achieve? Redefinition of H 1 “full beam” scenarios • Decrease the probability of stopping all of the choppers in open position by • applying control software procedures (can’t be eliminated, not safety related software!) • user will not be able to change the mode of measurement (modulation or pulse chapping) • Frame overlap chopper at 80 m will be rotation all the time (decrease the flux on the sample, can limit the imaging option on the instrument) • Used fixed smaller aperture in the guide system (reduction of science case) • User will be able to change the slits so the worst-case H 1 scenario is fully open slit system H 2 scenario will need to be handled with active monitoring • gamma monitors in the control hutch and near by the hot spot – safety component • incorporation of additional light shutter to link to the gamma monitor – safety component • Not clear answer from the radiation safety group how to handle this scenario It will lead to another delay in the sub-TG 3 for the cave and further installation process. 12
