6. Potential transport options There are several options to get Dubna from Moscow airports. Visitors arriving to Sheremetyevo or Domodedovo airports can use Aeroexpress trains finally arriving to the Belorussky Railway Terminal or to the Paveletsky Rail Terminal, respectively. Then, visitors need to take a Moscow Metro train to Savelovskaya Rail Terminal. After that, visitors can use either train or bus connection to Dubna. Trains to Dubna depart from Savelovsky railway station (Metro station Savelovskaya) of Moscow city. Please, get off the train at the last stop “Dubna”. Buses from Moscow to Dubna depart from Savelovsky railway station (Butyrskaya str.) as well. Detailed description and the schedules will be supplied to those who would desire to get such a journey. JINR also has its own transfer service, which will be available for participants of ECFA. The usual practice is that visitors are meet directly at the airport by a representative of the Organizing Committee and accompanied to Dubna by special transport.

7. Potential visits to the scientific facilities 7.1. JINR Basic Facilities JINR has a remarkable collection of experimental physical facilities: the only superconducting accelerator of nuclei and heavy ions in Europe and Asia – Nuclotron; DC-280 cyclotron, a core part of the future Factory of Superheavy Elements; heavy ion cyclotrons U-400 and U-400M with the record-breaking parameters of beams for experiments on heavy and exotic nuclei synthesis; unique neutron pulsed reactor IBR-2M for research in neutron nuclear physics and condensed matter physics; proton accelerator – Phasotron which is used for radiation therapy; the IREN-I facility dedicated to research in nuclear physics.

The Nuclotron accelerator is a strong-focusing proton synchrotron, designed to provide beams of protons with energy up to 12,5 GeV, heavy ions with energy up to 4.5 GeV/nucleon and polarized deuterons with energy up to 6.2 GeV/nucleon. The Nuclotron is based on the unique technology of superconducting magnets proposed at the Veksler and Baldin Laboratory of High Energy Physics.

DC-280 cyclotron, a core part of the Factory of Superheavy Elements being under construction 6

DC-280 cyclotron is a new experimental facility of JINR launched in the end of 2018. Accomplishing of the DC-280 is planned is one of the most important stages of the construction of the first in the world Factory of Superheavy Elements (SHE Factory). The project intensities of accelerated ions of the new cyclotron are an order of magnitude higher than those achieved previously in the world’s leading nuclear physics centres. This will ensure maintaining of the JINR’s leading position in one of the most important areas of modern nuclear physics – synthesis and study of properties of new superheavy elements of the Mendeleev Periodic Table. DC-280 is located at the Flerov Laboratory of Nuclear Reactions.

U400 U400M U400 and U400M cyclotrons were built to study nuclear structure and mechanisms of nuclear reactions. The experimental researches that can be performed using these facilities include synthesis of superheavy nuclei, study of chemical properties of superheavy elements, study of the structure of light drip-line nuclei, study of the resonance structure of nuclear systems beyond the drip line, and study of mechanisms of nuclear reactions with stable and radioactive nuclei (Flerov Laboratory of Nuclear Reactions).

IBR-2 is a fast periodic pulsed reactor. It is the only fast-neutron periodic pulsed reactor in the world. Its mail distinctive feature is mechanical modulation of reactivity with a movable reflector. The reactor is operated by the Frank Laboratory of Neutron Physics.

IREN (Intense Resonance Neutron source) is intended for experiments with the time-of- flight method in the neutron energy range up to hundreds keV that require precision spectroscopy of neutrons in the energy range from 0.1 eV up to hundreds of keV. Its operation is based on conversion of the electron beam on a tungsten target into primary neutrons (Frank Laboratory of Neutron Physics)

The Phasotron facility is the very first accelerator at JINR. Nowadays it is used in proton therapy for cancer treatment by broad and narrow proton beams of various energies – between 100 and 660 MeV (Dzhelepov Laboratory of Nuclear Problems).

“Govorun” Supercomputer is a project aimed at sufficient acceleration of complex theoretical and experimental researches in the field of nuclear physics and condensed matter physics held at JINR including NICA project. Supercomputer is based on the development of the heterogeneous platform of HybriLIT, and this will lead to increase of CPU and GPU performance. Updated computing cluster will allow carry out resource intensive and parallel computations in lattice QCD for research on the properties of hadron matter at high baryon density, high temperature and in the presence of strong electromagnetic fields, positively increase the efficiency of modeling the dynamics of relativistic heavy ion collisions, development and adaptation of software for the NICA mega-project on the new computing architectures of the major HPC market leaders – Intel and NVIDIA, to create an HPC-based hardware and software environment, to prepare IT specialists in all the required directions.

7.2. Facilities under construction

NICA The flagship project at JINR is the Nuclotron-based Ion Collider fAcility (NICA), th experimental facility of megascience class, supported by the Russian Government. It is a new accelerator complex designed at Veksler and Baldin Laboratory of High Energy Physics of JINR to study properties of dense and hot baryonic matter. The NICA accelerator complex consists of two superconducting synchrotrons – the Booster and the Nuclotron, which working as a tandem, supply via transfer channels the Collider with accelerated heavy ions. The latter is composed of two superconducting rings with two beam interaction points (IP). It is located in a new building (under construction).

Scheme of the NICA The Booster – beginning of mounting

The Booster is under mounting presently (February 2019). It is placed inside the yoke of the dismantled proton synchrotron Synchrophasotron that accelerated protons up to 10 GeV. The NICA complex will be equipped with three detectors:  the MPD detector to conduct experimental studies of hadron matter and its phase transitions in energy range s = 4 – 11 AGeV;  the BM@N detector, a setup already constructed, to study baryonic matter at fixed target experiment in energy range up to s = 4.7 AGeV;  the SPD detector to explore the nucleon spin physics in energy range s = 4 – 27 AGeV.

The major milestones of NICA project development are the following: - Development of injection complex, start of the Booster operation putting in operation the Booster, and starting data taking with fixed-target experiments; - Construction of the building for the collider, two detectors and beam transfer channels; 9

- Start of the Collider operation with symmetric heavy-ion beams; upgrading the beam intersection segment for operation with colliding beams of different kinds of ions at equal energy per nucleon (in this case, the magnetic rigidities of the Collider rings are different); - Upgrading the Collider rings with devices to control particle spin dynamics and polarized beam diagnostics, implementing experiments in spin physics with colliding beams of polarized particles.

Superheavy Elements Factory (SHE) Creation of SHE factory based on the high-intensity universal DC-280 cyclotron (A ≤ 238, E ≤ 10 MeV·A, I ≤ 20 pµA) in a new separate experimental building is a part of the DRIBs-III project according to the Seven-Year Plan for the Development of JINR 2010-2016 approved by the Committee of Plenipotentiaries of the Governments of the JINR Member States (CPP) in November 2009. The SuperHeavy Element Factory will increase the overall production of super-heavy nuclei by one-two orders of magnitude with respect to presently achieved rates. This will enable the studies of nuclear /atomic structure of heaviest atoms and open the door to the discoveries of new elements above Z=118 and of isotopes closer to the predicted shell closure at N=184.
