  9. G.Shirkov, Basic Facilities, 02.06.2005 LINAC – 800 ( first stage of the DELSY project,not budgetary facility) • LINAC-800 parameters: • energy – 800 MeV • average current – 50 mA • Applications of LINAC-800: • Free Electron Lasers • Material modification • Injector of Synchrotron Centre Free Electron Lasers at LINAC-800 (Bld.118) First 20 MeVbeam – the goal of 2005 Dubna Synchrotron Centre with the JINR participation is the most promising wayof synchrotron investigations and applications in the future.

  10. G.Shirkov, Basic Facilities, 02.06.2005 Phasotron - Dzhelepov Laboratory of Nuclear Problems (users’ request facility) • Fundamental Investigations: • DUBTO - Resonant behaviour of the both the pp- and nn+ systems, produced in 4He interaction. • MUON – Investigation of the muon properties and the muon interactions with matter. • FAMILON - The study of the two-particle muon decay on an electron and golston's massless boson. • -CATALISIS- Measurements of muon catalyzed fusion cycling rate temperature dependence in a binary mixture D/T in the temperature range 40-300 K. • Applied investigations: • Cancer therapy; • (~100 patients per year) • SAD- • Subcritical Assembly Driven by Proton Accelerator Fire accident in hall 4 on 09.04.2005 Phasotron and oncology facilities were not damaged at all!

  11. G.Shirkov, Basic Facilities, 02.06.2005 The main task: restoration of hadron oncology facilities at JINR as soon as possible • Two ways: • restoration of existed oncology facilities (~ 750 k$, ≤ 12 months) • creation of a new facility (synchrotron) specialized for hadron therapy • (~10 M$ with existed buildings, oncology beams and cabins, ~5 years )

  12. G.Shirkov, Basic Facilities, 02.06.2005 Working Plan to Restart the Hadron Therapy with Phasotron at DLNP Type of WorkPeriodCost Estimate • Halls Reconstruction6 LNP(100 k$) • Equipment Cleaning 1 1 and PaintingLNP(35k$) • Halls Cleaning ?LNP(100 k$) and Painting+100 k$ • Cables 6 LNP(100 k$) Communications +100 k$ • Equipment 4 LNP(100 k$) Repair+100 k$ • Accelerator 3 LNP(15 k$) Restart Works TOTAL12 monthsLNP( 450 k$) +300 k$

  13. G.Shirkov, Basic Facilities, 02.06.2005 IREN – Intense REsonance Neutronsource (facility is under construction at FLNP) • IREN consists: • powerful (10KW) electron linac • LUE-200 • plutonium subcritical multiplied target IREN project had been approved by JINR Scientific Council in June 1994 The first budget of the project was 3.7M$ It was planned to complete the project up to 1998.

  14. G.Shirkov, Basic Facilities, 02.06.2005 First Priority Experimental Tasks Scheduled for IREN with Budget and Manpower

  15. G.Shirkov, Basic Facilities, 02.06.2005 It was produced and delivered to JINR main HT elements of the linac LUE-200: • equipment for two RF modulators; • two accelerating tubes with accelerating rate 30 MeV/m; • SLAC klystron 5045; • SLED system and RF feeder; • the vacuum system; • the grid; • diagnostic systems. • In addition: • RF modulator was assembled; • RF, vacuum systems were tested; • the accelerator grid was precisely mounted ; • the pulsed electron source was tested and mounted on the grid; Electron gun testing The metallic plutonium fuel for multiplying target was manufactured at “Mayak” and delivered to JINR in Dec. 2004

  16. G.Shirkov, Basic Facilities, 02.06.2005 • The budget of the IREN project • 1994 - 3.7M$ • 2005 ≥ 4.5 M$ due to: • inflation of US dollar • increasing of material cost • increasing of manpower cost It had been invested now ~ 2.25 M$ including ~ 950k$ in 2000-2004 The rate of project financing ~ 300 k$/year The estimated time for startup the facility: 2012 • MoU between Kurchatov Institute and JINR was signed in February, 2005. • KI is ready: • contribute to the IREN project (~100k$/year); • to apply jointly with JINR to the Russian Government for a special grant (~1M$) Section grids of LUE-200 Cooperation with KI is the most promising way for completion of IREN in 2008
