SVD Schedule

In early 2012, a detailed schedule was worked out and is now maintained by C.Irmler (HEPHY Vienna)

More than 200 unique items (and growing) with dependencies, duration and responsible persons

MS Project & PDF versions are available at http://www.hephy.at/project/belle/belle2svd/schedule

SVD ready for installation in August 2015

ProductionMechanicsCoolingElectronicsSummary

Sensors (1/2) HPK

Large rectangular sensors: 130% of installed quantity delivered already Will issue an extra order for ~15% more in 2013

Small rectangular sensors: Design submission and order by November 2012 Delivery until June 2013

Construction database is being developed First filled with sensor data (objects, measurements,

transfers, …) Then also other objects

1 October 2012M.Friedl (HEPHY Vienna): SVD Schedule 5

Sensors (2/2) Micron

Trapezoidal sensors: 3 wafers with new p-stop design delivered in

August 2012, tested OK Beam test + irradiation + beam test in October 2012 After analysis: series production order by December

2012 Delivery until August 2013

Ladder Production Sites

Discussion among all parties during summer 2012 B2GM

Plan for sharing of production: L3: Melbourne L4: Tata (at CERN due to export restrictions) L5: HEPHY Vienna L6: IPMU

We also agreed that it is important to keep some flexibility in our plan, so that one site can help another if trouble/delay occurs

Origami Prototype Modules

Single Origami modules (HEPHY, 2010 and 2011)

Double Origami module (IPMU, 2012)

Both: collaborative effort of HEPHY, IPMU and Tata 1 October 2012

Mechanics: Minor Open Issues

Ladder mount on end rings Not finalized yet, but

converging Prototypes being prepared

Cooling for L3 hybrids heat pipes look promising,

now investigating1 October 2012

Acknowledging help from MPI & DESY engineers!

Mechanics Schedule

Overview: Overall design is completed Ladder mounts to be finalized by end of 2012 Carbon fiber rib prototypes now being produced Support cone prototypes in August 2013 End flange prototype by March 2013 Detailed SVD mockup by March 2013

ProductionMechanicsCoolingElectronicsSummary

Cooling

CO2 system in Belle II does not need inspection by Japanese government (capacity is too small) Will be operated by the KEK cryogenics experts

Cooling Mockup at DESY Operated with XFEL CO2 unit (similar to MARCO

which will become available by the end of 2012) Distribution & Routing of cooling pipes

Number of lines is defined First design for manifolds and routing exists 2 options for transfer lines (3 pipes in larger one or

pipe-in-pipe) APV25 cooling contact is converging
