ISTC CERN Collaboration 15 years of history Visit

ISTC – CERN Collaboration 15 years of history: • Visit of Snejinsk Scientific Director, Academician E. N. Avrorin to CERN/1994 • Meeting organized by Minister B. Saltykov and L. Riabev in Moscow/November 1994 • Russian Scientific Policy Committee for fundamental research held in Sarov/October 1995 • First ISTC Project approved in 1995(#121) Cryostat for NA 48 with Khrunichev Plant ……………. . • 2003 -decision to support 3 R&D Pilot Projects in view of the future long-term collaboration and construction of a new Linac 4 for the CERN Injection Complex

Collaboration between CERN and Russian Institutes within the ISTC Programme · From 1995: about 40 projects, some of them with multiple extensions, among them: Regular projects (financed by the ISTC) Regular projects with CERN co-funding 6 Partner Projects (financed by CERN) The majority of the projects are successfully completed; 5 are continuing; one project was terminated without execution because of drastic rise of price for raw materials Total projects volume 28 M$US of which ISTC contributed 11 M$US and CERN 17 M$US

Bogoroditsk Pb. WO 4 Crystals # 354 - # 354 B 1996 -2000 Spin off: PP #1718 for 10 M$US 2000 -2005 Spin off: Commercial contract with Bogoroditsk for more than 25 M$US for the same crystals for CMS 62’ 000 crystals needed for CMS Electromagnetic Calorimeter

Spin off: ISTC project 2039 crystal production technology of (Lu-Y)Al. O 3: Ce crystals for medical needs - generation of PET scanners CERN crystals used in medical imaging

CLIC study – Project # 3169 – Novgorod Institute of Applied Physics Gyroklystron schematics CERN is studing the feasibility of building a 3 Te. V linear collider based on accelerating structures operating at 12 Ghz Assembled gyroklystron

Ongoing ISTC Projects Partner Projects (funding from CERN): #3438 CMS / BTCP, Bogoroditsk 30 k$US R&D for mass production of Pb. WO 4 endcap crystals (spin off #1718) Jan. 2007 – Jan. 2010 Co-funded Projects: #1639 ATLAS/ IHEP, Protvino/ Snejinsk : ISTC: 375 k$US, CERN: 506 k$US Design and development of Tracking detector (Muon Drift Tube chambers) 2001 – 30 Nov. 2008 (due to great success had multiple prolongations) Has been extended till June 2010 with CERN add. funding of 230 k$US

Monitor Drift Tubes (MDT) Chambers for precise measurements of muon trajectories in the ATLAS Muon Spectrometer # 1639; Protvino, Dubna, Snejinsk 2001 - 2010 208 MDT Chambers must be produced with highest uniformity

Ongoing ISTC Projects Pilot Projects for the Linac 4 2004 -2009 (Regular projects funded by EU) # 2875 – Novosibirsk/RFNS-VNIITF, Snejinsk: 550 k$US Coupled Cavity Drift Tube Linac Structure+ cold model of SCL structure (100 -200 Me. V) +145 k$US added by CERN # 2888 – ITEP, Moscow/VNIIEF, Sarov: 500 k$US Drift Tube Linac (DTL) structure with magnetic focusing (“Alvarez”) (3 -40 Me. V) +30 k$US added by CERN # 2889 – IHEP, Protvino/VNIIEF, Sarov: 500 k$US DTL structure with focusing by RF quadrupoles (DTL-RFQ) (3 -40 Me. V)

Pilot Projects for the Linac 4 and the ISTC Projects #3889 and 3888 for the CCDTL structures - some dates · February 2007 - Meeting at ISTC headquarters in Moscow between CERN and Russian Institutes – decision to prolong all three Linac 4 Pilot Projects. CERN provides additional funding to ISTC # 2875 (Novosibirsk/RFNS-VNIITF, Snejinsk) to ensure future production capacity for the CCDTL structures. · March 2008 – CERN invites representatives of the ISTC and of the European Commission to discuss further cooperation for Linac 4. · Spring/summer 2008 - The Project for CCDTL structures is being prepared for submission to ISTC by our Russian partners; cost estimation 2. 7 M$: decision to split it into two ISTC Projects- Regular and Partner one. Requested funding from ISTC – 1. 35 M$, with equal CERN contribution. · July 2008 – CERN invited to ISTC to present a summary of the collaboration within the ISTC Programme to the delegation of the European Commission. · December 2008 – The ISTC Governing Board approves both Projects but with smaller funding (0. 93 M$) for the Regular Project. >negotiations……. . modified Workplan and financing · June 2009 – Partner Project Agreement #3889 and Memoranda of Agreement 3888 and 3889 p approved by ISTC, BINP and CERN
