Metrology EW bellows

Minute 40

Plug-in:

• Make or buy plan ongoing
• Asset creation

Mechanical table assembly:

• Assembly procedure is almost finished
• Cycling test will begin soon

TCC:

• Christophe (CEM) will update the software to be easier to understand/ have values
• Malik will work on it on the hardware part and for a potential chiller bath

Absorber materials update:

• 3 CuCD blocks with dry machining good after a 650° thermal treatment (factor 3 better and factor 10 from total outgassing)
• Inermet to be sent to metrology – No updates last time

Production:

• First jaws copper part flatness measurement = 42um and second one = 70um
• Welded bellows brought to metrology, finished next week (no better precision on it)
• Drawings updated of the shaft beginning of the next week
• Cooling pipes in ultrasound control, waiting for the report. Mini. Thickness of the tubes=0.60mm
• Tank extremities ongoing
• CuBe folding finished, then welding
• 350 cleaned parts to be received finally next week

Additional screws:

• Rodriguez declined it because of the pitch
• Moog answer the requirements -> visit to come  
• Ewellix answer the requirements, we can visit the factory – Delays = 39 weeks, check the feasibility
• SKF, Umbra, Bosch not possible
• Schaeffler answer the requirements, materials to defined -> very good delays/ costs
• Meeting with S. Sgobba for the materials alloy and corrosion restiance

Graphite tapering procurement:

• Asked to Pablo to order 2 blocks – 2 more block only if metrology is good on the first 2 ones.

Update on planning:

Update for the serie:

Others:

• Waiting for the first and last RGA tests final reports
• Tools for flatness measurement: check the compatibility (point 4 or 132)

EDMS:

• 2172391 for the collimator assembly procedure
• 2718080 labelling for the proto/ serie
• 2702554 collimator plates production
• 2664160 collimator production
• 2355344 NCR TCPPM bellows
• 2733845 metrology EWB bellows
