Towards a tender specification • Where are we? • The following is a check list of what we have accomplished to date:- • Safety review of the Hydrogen safety; ✔ • R & D work on the Window fixing – welded or bolted ✔ • Safety review of the hydrogen delivery system ✔ • Selection of Cryocoolers; ✔ • Cryogen condense pot, cold intercept connections etc ✔ • Design & validation of the Coil Former & Cold Mass support ✔ • Internal pipework connection design & arrangement ✔

Drawing & design information on the AFC • The repository for all the AFC drawings is at RAL; • Chris Nelson is the keeper of this information; • Oxford (Stephanie Yang) will ensure that Chris gets the latest version of all the cooling AFC drawings; • However, for read only information on the AFC 3-D model, this could be downloaded from our web pageand Stephanie will demonstrate how easy this could be done.
Towards a tender specification • The following is a check list of actions that have not been accomplished:- • Formal response to the H2 R&D review; • Final design details and specifications on:-HTS Leads; Power supply; vacuum pumping; rail & docking system; N2 & helium supply; quench protection etc; • QA procedure for window measurement; • Burst pressure test (3 to 4 sets) for the current window geometry; • Finalising a bidders list, vendor qualification inspection and a set of well defined Tender specification;
Summary • A fair amount of work still to be done before we are ready for tender; • Our priority is on making sure that the interface parameters are well defined and that the tolerances are achievable; • We are still getting feed back from the Spectrometer solenoid manufacture on how we should improve our tender specifications to avoid expensive changes after contract signing; • The AFC Work Group will be re-activated so that we can received more feed back and suggestions from parties outside RAL and Oxford before we conclude the tender specification;
