CBM(BM@N) STS design constraints• Coverage:

― rapitidies from center-of mass to close to beam

― aperture 2.5° < < 25° (less for BM_N)

• Momentum resolution ―δp/p 1% ― field integral 1 Tm, 8 tracking stations― 25 µm single-hit spatial resolution ― material budget per station ~1% X0

• No event pile-up― 10 MHz interaction rates― self-triggering read-out ― signal shaping time < 20 ns

• Efficient hit & track reconstruction close to 100% hit eff. > 95% track eff. for momenta >1 GeV/c

• Minimum granularity @ hit rates < 20 MHz/cm2

― maximum strip length compatible with hit occupancy and S/N performance

― largest read-out pitch compatible with the required spatial resolution

• Radiation hard sensors compatible with the CBM physics program

― 1 × 1013 neq/cm2 (SIS100)― 1 × 1014 neq/cm2 (SIS300)

• Integration, operation, maintenance― compatible with the confined space

in the dipole magnet


• Aperture: 2.5° < < 25° (some stations up to 38°).• 8 tracking stations between 0.3 m and 1 m downstream the target.• Built from double-sided silicon microstrip sensors in 3 sizes,

arranged in modules on a small number of different detector ladders. • Readout electronics outside of the physics aperture.

Through years 2008-2013 the CBM-MPD STS Consortium demonstrated self-sustained growth of R& D activity which could be successfully accomplished within 1,5 -2 years

The Conclusions

In 2013 common GSI-JINR project started with resources (@around 3 M USD) released to develop corresponding infrastructure for massive production of modules and, especially, supermodules at LHEP JINR by mid-2015 for the BM@N and CBM STS projects, firstly, and NICA-MPD ITS, afterwards Young generation recruitment and training is the basic problem of the project to be discussed tomorrow in more details as well as more involvement of physicists from the Universities of both capitals of Russia
