Investigations at Phasotron


A multi-room Medico-Technical Complex for radiotherapy with hadron beams from Phasotron

Treatment room No 1 for proton therapy of tumors seated in the head, neck, and trunk


Project DRIBs (phase I):• 6He ions were accelerated at the U400 cyclotron;• The efficiency of the system was 1.5% (the projected value is 15%); •a number of modernizations in the system units were made, which were aimed at increasing the efficiency of extracting 6He (8He) nuclei from the catcher and transforming them into the accelerated beam;•a mechanical part of the system for extracting the 6He and 8He beams from U-400 was created;•the systems of diagnostics of the extracted from U-400 6He and 8He beams, vacuum system for the beam lines and physical set-ups as well as control systems were developed.

Intensive research and design works in the frames of the Project DRIBs (phase II):•Modernization of the microtron’s system and transport line, design of the transport line delivering an electron beam to the uranium target;•Design and testing of the target-ion source complex;•Calculation and development of a transport line for beams of single-charged ions-products of uranium fission.•Development of the diagnostics system;•Development of the charge breeder on the basis of the ECR ion source;•Elaboration of radiation protection measures.

The Status DRIBs and its future development in 2002


U400R cyclotron

Project U400R based on the U400 cyclotron facility

The main goals of reconstruction are:•Increasing beam intensities for masses with A 50 and energy range near 5 MeV/nuclon up to 3 pa.•Variation of the ion energy on the target with coefficient near 5.•The ion beam emittancies on the target on the level 10 mm mrad.•The ion beam energy spread on the target on the level (2 3) 10-3.•Decreasing of the main magnet power consumption from 1000 kw up to 250 kw.•Completion of the cyclotron system by modern equipment.•Now near finishing is the phase of the computer simulation and starting the phase of the designing.

2. JINR Technical Policy and Infrastructure

In order to improve and develop the technical policy and infrastructure at JINR, a supplement to the Programme of JINR’s Scientific Research and Development for the years 2003-2009 will be prepared for the session of the 95th

Scientific Council (January 2004). This activity has been started by a working group. This group was established by the JINR Directorate.

The supplement will include the status, proposals of maintenance and development as well as requests for necessary resources in 2003-2009 for:

•Basic facilities•Energy, heating and water•Experimental workshops•Technical infrastructure of laboratories•Radiation, nuclear and industrial safety•Information technologies•Buildings, Transport, Social infrastructure•Staff policy

The main reason for the aging of the JINR personnel: JINR is not attractive for the younger generation now due to:• low salary;• limit of modern scientific equipment in Laboratories;• housing and living problems;• social problems A special group was recently organized in order to study ways of making JINR more attractive for young scientists and workers.
