R&D project possibilities

M. Oinonen, PHENIX Forward Upgrade meeting, Prague, 20-21 Oct 2006

Internal memo circulated among the involved persons of HIP DL.

• based on Edward Kistenev’s visit in Helsinki (Aug-06)

Proposal:

• separate prototyping & mass production projects• prototyping as R&D efforts, mass production as “service

provider”

R&D project considered important since use of existing resources crucial

green light for prototyping in DL

R&D project possibilities

M. Oinonen, PHENIX Forward Upgrade meeting, Prague, 20-21 Oct 2006

Plan:

• JYFL provides mechanical workshop for tools• MSc Henri Seppänen conducts the prototyping in Helsinki

• PHENIX provides some manpower for assembly in Helsinki?

Crucial:

• H.S. funded by HIP, Univ. of Helsinki and JYFL (to be confirmed)• H.S. is expected to finish his PhD on ultrasonic bond quality

during 2007• no costs for equipment & premises for prototyping phase

prototyping feasible from the point of view of DL

Prospects for mass production

M. Oinonen, PHENIX Forward Upgrade meeting, Prague, 20-21 Oct 2006

Prototyping should be successful

• decision upon the mass production relies on prototyping

Expectation: mass production as service provider, not an official member of the collaboration

• co-operation can also take place between an institute and “a service provider”…

to be seen…
