Milestones and Schedule of SVD Construction
Markus Friedl (HEPHY Vienna)on behalf of the Belle II SVD Collaboration
BPAC October 2012
What Happened Since February? Sensors Details by T.Tsuboyama
Micron delivered trapezoidal sensors with new atoll design Construction database under development
Ladder assembly Details by Y. Onuki Double-origami ladder built at IPMU, Japan 4 construction sites for series production
Mechanics Details by I.Gfall Design completed for all layers
Cooling Details by C.Niebuhr Detail design converging Mockup tests ongoing
Electronics Readout details by myself, integration by K.Hara DC/DC converters and other parts tested FADC design completed, layout in progress

Concerns/recommendationsIn Feb 2012 BPAC report
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

Ladder Production Schedule
Full ladder prototypes (L5 & L6) by February 2013 Followed by final optimization of jigs Series production for ~1 year starting
summer/autumn 20131 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
M.Friedl (HEPHY Vienna): SVD Schedule 13
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
