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

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, 200913-th CBM, GSI, March 10, 2009
CBM STS Sensors: Pilot Batch
(M.Merkin) Manufacturer RIMST– Zelenograd, Moscow region
Active area - 40.0 x 60.0 mm2Strips pitch on both sides of detectors - 58
µStereo 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
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

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

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
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
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
