Neutron Guides – Bunker’s Wall Feedthrough interface Neutron Guides – Bunker’s Wall Feed-through interfaces must be updated. Instrument teams are required to: • Provide updated Neutron Guide model • Provide updated feed-through envelope, keeping in mind: § Wall blocks positioning accuracy of +/- 30 mm § Shimming § Alignment § Etc. All requirements and the newest information can be found on the Confluence page:

Neutron Guides – Bunker’s Upstream Supports interface The Bunker Team was requested to design instrument supports, upstream of the Bunker Wall. Gabor Laszlo would like to integrate an additional plate on top of supports, which would allow to perform adjustment in XZ plane – development is ongoing at Gabor’s side. From mechanical point of view upstream supports have been approved, thus no further development is needed.

Instrument’s Utilities – Bunker’s Utilities Feed-through interface must be implemented. Status on 2018 -10 -16: • Design of utilities is ongoing at ESS’s side (by Talal Osman) From mechanical point of view utilities feed-through have been approved, thus no further development is needed.
