Project status
• The instrument was broken down into separated products/components
• SKADI Product Breakdown was created• The work packages were assigned to the corresponding
laboratories• For each component a requirement list is created and
constantly updated• Currently we are working on the development of components• We are starting with the design phase beginning of September

Project status
We need: VPN-Access for download of CATIA V6 and license CAD-Data for SKADI place in the neutron guide hall with
information for beam implementation and floor requirements CAD-Data for Bunker with information on the access, pipeline
implementation etc. Data for Place for neutron extraction in the target monolith In future: shielding calculation, CAD-Modell from chopper
housing Would be useful: Information/Requirements for Standards for
example for pipeline (witch norm, diameter, flanges etc.)
