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)

Dubna Synchrotron Centre with the JINR participation is the most promising way of synchrotron investigations and applications in the future.

First 20 MeV beam – the goal of 2005


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.

Phasotron - Dzhelepov Laboratory of Nuclear Problems(users’ request facility)

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!


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 )

The main task: restoration of hadron oncology facilities at JINR as soon as possible

IREN – Intense REsonance Neutron source (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.


First Priority Experimental Tasks Scheduled for IREN with Budget and ManpowerFirst Priority Experimental Tasks Scheduled for IREN with Budget and Manpower


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.

Electron gun testing

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;

The metallic plutonium fuel for multiplying target was manufactured at “Mayak” and delivered to JINR in Dec. 2004


Section grids of LUE-200

MoU between Kurchatov Institute and JINR was signed in February, 2005. KI is ready:• contribute to the IREN project (~100k$/year);• to apply jointly with JINR to the Russian Government for a special grant (~1M$)

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$/yearThe estimated time for startup the facility: 2012

Cooperation with KI is the most promising way for completion of IREN in 2008
