Updates
• Global 3D assembly updated, no severe problems/clashes• T1 RF network dimensions updated• WPS arms machined• Mock-ups under machining, brazing starts next week

Adjustable DBQ support
• Supports for T0 ready• The rotation of the magnets has some implications
(adjusting knobs on the inside)• Some modifications might be required – investigation
needed• Design for T1 tricky to implement due to Epucret
design

Adjustable V-supports
• Finalised design and drawings
• Adequate for proof of concept, still a bit rough
• Fixed supports already on Epucret
Stay with fixed supports (both V and DBQ) and organise a side project, perhaps on second Epucret girder with dummy loads?

BPM deletion drift tube• Clash 15mm
• Bellow compression 7mm
• Drift tube play in magnet 5mm
• If decided to be replaced, needs to be done before magnet assembly
5mm

Vacuum
• ‘Baseline’ design almost ready
• Vacuum forces are significant
• Shall we proceed with baseline design or launch a design project for force cancelation?
• 2 quick proposals

MBQ support
• Only piece missing before floor drilling
• Concrete block needs to be replaced
• Shall we assume the base plate as reference and produce steel support block?

U-clamps
• For MB:• In principle CLEX design can be used• Compatibility check pending
• For DB:• Same design as T0.1• Probably not compatible with adjustable
V-supports
• Redesign needed?
Mysterious additional support in CLEX

• According to test plan, 22 temperature sensors are foreseen for each TBM
• Current architecture (NI cDAQ) allows 32 sensors per box
• Remaining signals (flow meters, control valves, heaters) will be connected to 4th electronics box
• Total of 4 boxes, connected via USB to central PC
• Room for expansion• Optional upgrade to cRIO system with
embedded CPU for increased robustness

Next tasks
• Critical path:• WPS arms assembly• T1 MB cradles machining• Girders fiducialisation• Floor drilling• Girders installation
• In parallel:• Cooling rack assembly – already started• PETS T0.2 fiducialisation
