Lavs Issues• Lav 12.• Tube 26-28.• Planning future activities.• Conclusions.

Lav 12.• Details drawings are ready.• Panel light tight has been defined (inner radius 280mm

material aluminum 0.4mm).• Orders for top part and lower carriage has been placed

and the company received both of them.• Next step is to interact with production company to

finalized drawings for construction.• The delivery time is two month after the approval of final

drawing for construction. • The company is preparing a detail fabrication steps

planning.

Details drawings of Lav 12

Tube 26-28 status• A final versing of drawings has been made and approved. • We verify fabrication drawings and final dimensions and

tolerances.• Final drawing has been summited to FERDI and Olivier for

further comments.• The deliver schedule has been update.• The deliver of tube 26-28 at CERN is envisaged in the end of

April 2014 (22/04/2014).• A late of delivered of the special stainless steel AISI 304LN

has caused a week of delay in the pervious schedule. • All material for construction now it is at the company and

reparation is taking place for welding.

Planning of future activities

• Mounting and test the Lav 12 structures at the company to verifying the mechanic.

• The transportation of LAV 12 implies a new insulation case and a new isolation system.

• Tooling for mounting and handling LAV 12 Mechanic and crystal must be designed and made.

• Verification of construction of Tube 26 and 28 and tests. • Installation of the tube 26 and 28 and the rest of LAVs in

the experimental area.

Conclusions• We can consider to receive the lav 12 in Frascati at the

end of April 2014 and transport it at CERN during the summer time.

• Integration and organization of the transportation of LAV12 can take place in the following three months.

• The Tube 26-28 can be delivered at CERN end of April.• After the end of March we can installed the rest of

LAVS.
