3. Energy – need to reach at least 500 GeV CM as a start Luminosity – need to reach 10^34 level Linear Collider – two main challenges

4. How to get Luminosity To increase probability of direct e + e - collisions (luminosity) and birth of new particles, beam sizes at IP must be very small E.g., ILC beam sizes just before collision (500GeV CM): 500 * 5 * 300000 nanometers (x y z) Vertical size is smallest 5 300000 500

5. ILC Parameters Parameter range established to allow for operational optimization

23. Joint Institute for Nuclear Research Dubna, Russia International Intergovernmental Organization ILC siting and conventional facilities in Dubna region

24. Advantages of the ILC construction in Dubna: 1.The presence of JINR as a basic scientific and organizational structure. JINR is an international intergovernmental organization, which includes 18 Member States and 4 States, which are associated members. 2.The proposed territory is extremely thinly populated and practically free of industrial structures, rivers and roads. The proposed placement of the accelerator tunnels in relatively dry drift clay excludes the influence on abyssal distribution of the underwater. 3.The area is absolutely steady seismically and has stable geological characteristics. 4.A flat relief and the unique geological conditions allow one to place ILC on a small depth (about 20 m) and to perform construction of tunnels, experimental halls and other underground objects with the least expenses, including open working. 5.The extremely attractive feature of placing the ILC complex on the chosen territory is a unique opportunity to solve the problem of value at the purchase of land. Prevalent legal practice makes it possible to get the land of the ILC location to permanent free use just as it has been done for JINR, according to the agreement between JINR and the RF government.

25. 6. There are sources of the electric power of sufficient capacity in the area of the ILC construction: transmission line of 500 kV, the Konakovo electric power station (EPS) and the Udomlia atomic power plant (APP). 7. The developed system of transport and communication services, advantageous location, good highways and railways, water-way (the Volga river basin), good position in the European region; 8. Presence of a modern network and information infrastructure, including one of the largest center in Europe the “Dubna” Satellite Communication Center. 9. A special the economic zone established in Dubna in December, 2005 provides preferential terms for development and manufacture of high technology technical production. 10. Dubna has a powerful scientific and technical potential. The developed infrastructure makes it possible to involve additionally specialists from world scientific centers into the already formed international collective of highly- qualified scientific manpower providing comfortable conditions for them to work. This guarantees a high quality of investigations on ILC and obtaining of new research results of fundamental scientific importance.

27. Dubna Siting: Layout of ILC in the Moscow Region Moscow region Tver region

28. Area and Climate There are no any national parks, biological reservations, any religious and historical places an the planned area. There are no new projects planned to develop on the allocated territory. It possible to avoid purchasing land and get the development area for free use without time-limit; like that has been done for the international intergovernmental organization the Joint Institute for Nuclear Research by the existing agreement between the JINR and the Government of the Russian Federation. The area is thinly populated, the path of the accelerator traverses 2 small settlements and a railway with light traffic between Taldom and Kimry. Possible “line” crosses only the railway to Savelovo (of low utilization) and the River Hotcha with a very small flow rate. The climate is temperate-continental. The mean temperature in January is –10.7  С. The mean temperature in July is +17.8  С. The mean annual rainfall is 783 mm. The mean wind speed is 3.2 m/s. Strong winds (15 m/s) blow only 8 days/year. According to the climatic parameters, the territory of Dubna is considered to be comfortable.

29. The area of the proposed location of the accelerator is situated within the Upper Volga lowland. The characteristic feature of this territory is the uniformity, monolithic character of the surface. The existing rises of the relief in the form of single hills and ridges have smoothed shapes, soft outlines and small excesses. The territory of the area is waterlogged. The absolute marks of the surface range from 125 to 135 m with regard to the level of the Baltic Sea. The difference of surface marks is in the range of 10 m only on the base of 50 km. Relief

30. The ILC linear accelerator is proposed to be placed in the drift clay at the depth of 20 m (at the mark of 100.00 m) with the idea that below the tunnel there should be impermeable soil preventing from the underlying groundwater inrush. It is possible to construct tunnels of the accelerating complex using tunnel shields with a simultaneous wall timbering by tubing or falsework concreting. Standard tunnel shields in the drift clay provide for daily speed of the drilling progress specified by the Project of the accelerator (it is needed for tunnel approximately 2.5 y’s).

31. The area of the proposed location of the accelerator is situated within the Russian plate – a part of the Eastern European ancient platform – a stable, steady structural element of the earth’s crust. The Russian plate, like all the other plates, has a well-defined double-tier structure. The lower tier or structural floor is formed by the ancient – lower Proterozoic and Archaean strata of metamorphic and abyssal rocks, which are more than 1.7 billion of years old. All these strata are welded into a single tough body – the foundation of the platform. The area of the ILC accelerator is located in the southern part of a very gently sloping saucer-shaped structure – the Moscovian syneclise. Alluvial deposits i.e. fine water-saturated sands, 1-5 m of thickness. Below one can find semisolid drift clay of the Moscovian glaciation with exception of detritus and igneous rocks. The thickness of moraine deposits is 30-40 m. Geology

32. Power and energetic The northern part of Moscow region and the neighboring regions have a developed system of objects of generation and transmission of electrical energy. There are first-rate generating stations: the Konakovo EPS (electric power station, ~30 km from Dubna) and the Udomlia APP (atomic power plant, ~100 km from Dubna). Two trunk transmission lines with the voltage 220 kV and 500 kV pass through the territory of Dubna. The investigation of possibilities of the power supply for the accelerator and its infrastructure with the total power up to 300 MW gives the following variant: Construction of the power line - 220 kV, 35÷40 km long, directly from the center of generation – the Konakovo EPS to the Central Experimental Zone of the accelerator with a head step-down substations 220/110 kV. It will require the investment in larger amount but the cost of power obtained directly from the centers of generation will be lower for 40÷50 % (from 0.05$ per 1kWh down to 0.02-0.03 $ per 1kWh in prices of 2006).

34. Chronology of JINR in ILC December 2005 – GDE in Frascati – A.N.

36. Documentation and Cost Estimation Russian State Project Institute (RSPI, Moscow) Official document from Russian State Project Institute (RSPI, Moscow) with estimations on: Conventional facilities cost Siting (tunnel, land acquisition) cost and time schedule Energetic and power cost Operational cost Labor cost July 2006 (for Vancouver GDE): JINR prepared and filled the necessary documents for possible ILC hosting to BCD (Conventional Facilities part), so called Site Assessment Matrix. The overall value on consolidated estimated calculations in the prices of year 2006 for civil engineering work, underground and surface objects of the main construction gives the sum in order of 2,3 B$, including 1 B$ of costs of the tunnels construction for linear accelerator, all its technological systems and mines. Cost of power supply objects which will provide electric power directly from generator sources with special (favorable) cost of energy (tariff) is of order of 170 M$. November 2006 (for Valencia GDE): JINR prepared and filled the necessary documents as a sample site for possible ILC hosting to RDR (Work Breakdown Structure - WBS) – in a special required format with all the details on infrastructure parts. This document was also prepared with RSPI and submitted by Design Cost Board of GDE.
