Discussion pointsTBM meeting23/09/2015

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
