5. Russia and the LHCb upgrade
Mass production of scintillating fibre modules has just started at Kurchatov Institute in Moscow (Production Readiness Review this Thursday)
KI is expected to produce a large fraction of fibre mats: this implies a considerable contruction effort running 7/7 days for a period of >1 year, to be in time for the SciFi tracker installation in 2019.
Given the excellence of Russian scientists, engineers and scientific infrastructures we are confident that this ambitious goal can be reached if Kurchatov group receives soon adequate financial and manpower support

6. Russia and the LHCb upgrade
Russia is a major contributor to the LHCb Upgrade (See Addenda N.01 and 02, CERN-RRB A and CERN-RRB to the Memorandum of Understanding).
The corresponding financial commitments comprise 3 MCHF towards CORE items, and 1.2 MCHF of CORE common project items contributions.
The most significant Russian contribution to the LHCb Phase-I Upgrade is to the construction of the scintillating-fibre (SciFi) tracker:
A contribution of 1.1 MCHF is expected from Russia to purchase the fibres which are being supplied right now: this contribution is of the highest priority for the success of LHCb upgrade !
A crucial contribution to the construction of the SciFi tracker is expected from Kurchatov Institute: full financial and manpower support to this group is urgent and of vital importance.

Summary
LHCb is producing a large number of beautiful physics results with leading contributions from many excellent Russian colleagues: we warmly thank the Russian Institutions for the invaluable support given to our collaboration.
LHCb is preparing a challenging upgrade, with key Russian contributions: we are wholeheartedly grateful to Russia for the attention given to this project and we count on the full support to the major items under the responsibility of Russian groups as well as to the common project items.
We very much hope that long-standing Russian participation in LHCb can continue also for the future upgrades now under discussion (see the Expression of Interest CERN-LHCC ). The excellence of Russian scientists would be invaluable in many areas of this project, one being for example, the construction of a new tungsten-based sampling electromagnetic calorimeter.
