3. Detector Laboratory (DL) in generalhttp://www.hip.fi/research/detlab/index_en.htm Origin at 80’s along with CERN-based (DELPHI) research at Univ. of Helsinki (UH) and Helsinki University of Technology (HUT) R. Orava, “The SEFT Detector Laboratory and its Role in Finnish High Energy Physics”, report HU – SEFT I 1996 – 04, University of Helsinki. 1) Support laboratory for all the HEP-based research in Finland & 2) Support for other users, if resources allow for: groups, institutes, companies From 2001 in Physicum, Kumpula, as a joint organisation of the Helsinki Institute of Physics and the Department of Physical Sciences of UH M. Oinonen, PHENIX Forward Upgrade meeting, Prague, 20-21 Oct 2006

4. Infrastructure / premises 107,5 m2 clean rooms (class 100 and 1000) + large main laboratory, both shared between HIP and UH projects ALICE until Aug-06 & TOTEM until mid-07 M. Oinonen, PHENIX Forward Upgrade meeting, Prague, 20-21 Oct 2006

10. 715 ALICE SSD modules done in HelsinkiM. Oinonen for the SSD collaboration First group to finish the task: 700 silicon strip detector (SSD) modules assembled until 29th of May 2006 Status on 31st of May 2006 Source: http://sbgat167.in2p3.fr/ssd_stat/ M. Oinonen, PHENIX Forward Upgrade meeting, Prague, 20-21 Oct 2006

11. R&D project possibilities • 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 M. Oinonen, PHENIX Forward Upgrade meeting, Prague, 20-21 Oct 2006

12. R&D project possibilities • 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 M. Oinonen, PHENIX Forward Upgrade meeting, Prague, 20-21 Oct 2006

13. Prospects for mass production • 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… M. Oinonen, PHENIX Forward Upgrade meeting, Prague, 20-21 Oct 2006

14. SWLI in nondestructive quality control of ultrasonic bonds in 3DH.Seppänen, I.Kassamakov, E.Haeggstrom, M.Oinonen et al. SWLI = Scanning White-Light Interferometry Certain spTAB bond height ensures a certain bond strength  Nondestructive quality control for ultrasonic bonds H. Seppänen et al., Proc. of the SPIE Photonics North, September 27-29, 2004, Ottawa, Canada & to be published. M. Oinonen, PHENIX Forward Upgrade meeting, Prague, 20-21 Oct 2006
