3. The Starting Point 13-th CBM, GSI, March 10, 2009

4. The Consortium tasks for 2008 Technical task definition for CBM STS ladder section (ALL) A pilot batch of Russian-made CBM STS Si sensors (SINP) Design and production of specific mechanics sample elements (Igolkin@KRI) Development n-radiation site the CBM STS components (KRI Cyclotron Lab, SPb) Task Force interaction improvement (ALL) Infrastructure development of the Consortium sites (KRI,JINR) Support of microcable production team in Kharkov via JINR-GSI cooperation 13-th CBM, GSI, March 10, 2009

5. CBM STS Ladder: Steps to Technical Task Definition (ALL) To agree of ladder design To agree of sensor topology To agree of connection to FEE Solution AGREED : flat semi-tiling of sensors on the 3D CF support ladder 13-th CBM, GSI, March 10, 2009

6. CBM STS Sensors: Pilot Batch (M.Merkin) Manufacturer RIMST– Zelenograd, Moscow region Active area - 40.0 x 60.0 mm2 Strips pitch on both sides of detectors - 58 µ Stereo angle - ±7.5degrees Number of strips on each side - 1024 (8 readout chips) With bondning/test pads topology suitable for TAB bonding (standard for the whole CBM STS !) Status : Draft of the contract (three mile stones!) is ready, pending on baby-sensors photomask files accomplishment (Merkin). Expected time for the first batch is July 31 13-th CBM, GSI, March 10, 2009

7. CBM STS: CF sample prototypes (S.Igolkin) 1/2 Technical drawings of the 4-th station have been accomplished but found not to fit the magnet size ( currently passed for the ANSI calculations) Jigs and accessories (vacuum oven for the CF ladder processing) are under design and production Imitating samples for the 3-sensor module and sensor support pins manufactured and tried for the rigidity 13-th CBM, GSI, March 10, 2009

8. CBM STS: CF sample prototypes (S.Igolkin) 2/2 13-th CBM, GSI, March 10, 2009

9. Radiation test site @ KRI, SPb,RF (V.Jakovlev & S.Lashaev, KRI ) 17 MeV pBe->n or DD->n? From 9Be(p,n)9B (g.s.) reaction; From 9Be(p,n)9B* reaction; 9Be + p  4He + 5Li + n – 3.5 MeV  8Be + p + n – 1.7 MeV  2 4He + p + n – 1.6 MeV

10. Task Force Interaction Improvement 1/3 To keep the teams having a clear joint goal each year (demonstrator test policy with tests in Protvino) To develop the infrastructure of the key sites (restoration of rooms and procurement of capital equipment) To Organize regular work Work Meetings 13-th CBM, GSI, March 10, 2009

11. Task Force Interaction Improvement 2/3: In-beam tests in Protvino 13-th CBM, GSI, March 10, 2009 Thanks Thanks to Yuri Zaitsev, ITEP for funding!

12. Task Force Interaction Improvement 3/3 2-nd Work Meeting of Consortium in Protvino June, 2008 3-d Work Meeting of Consortium in Sortavala, Karelia, June 1-4, 2009 13-th CBM, GSI, March 10, 2009

13. 2008 Achievements The Consortium chain started to operate as a whole Mechanical design of the ladder almost accomplished n-irradiation site @KRI 20 MeV cyclotron evolved Preparations for prototype manufacturing undertaken @ KRI(CF production, bench for the C-I-V measurements), JINR (Assembling&Certification) First stage of organization of the CBM STS in-beam testing site @ Protvino realized Additional funding for Kharkov and Dubna teams acquired for 2009 via JINR-GSI scientific cooperation Grants for the 3-d Work Meeting gained from RF focused funding agencies (ISTC) 13-th CBM, GSI, March 10, 2009

14. Tasks to remedy in 2009 The mismatch of the STS size and the clearance of the Magnet n-XYTER FEBs supply for the JINR team CF Prepreg supply for Igolkin Mold manufacturing for Igolkin Other problems could be resolved locally 13-th CBM, GSI, March 10, 2009

15. Basic Problem: Keep going on grants only

16. 2009 Tasks and their sharing Demonstrator 1: A 3-sensor module prototype Organization of in-beam tests in Protvino, November, 2009 Formulating irradiation plan for KRI Cyclotron team for 2009 Testing bench with collimated Ru-106 betas @ JINR to operate with n- XYTER FEB read-out Production of CF parts for the full ladder prototype Cooling system definition work plan (additional funds application) Analogue long cable conceptual bench tests based on FEB and existing Demonstrator-0B and n-XYTER FEBs Attraction of new members to Consortium (Czech Republic for sensor production?) 13-th CBM, GSI, March 10, 2009

17. Thank you for your attention! Acknowledgments to all many Consortium members not mentioned! 13-th CBM, GSI, March 10, 2009
