| MOY02 | NICA Ion Coolider at JINR | 12 |
|
||
| The Nuclotron-based Ion Collider fAcility (NICA) is under construction in JINR. The NICA goals are providing of colliding beams for studies of hot and dense strongly interacting baryonic matter and spin physics. The accelerator facility of collider NICA consists of following elements: acting Alvarez-type linac LU-20 of light ions at energy 5 MeV/u, constructed a new light ion linac of light ions at energy 7 MeV/n and protons at energy 13 MeV, new acting heavy ion linac HILAC with RFQ and IH DTL sections at energy 3.2 MeV/u, new acting superconducting booster synchrotron at energy up 600 MeV/u, acting superconducting synchrotron Nuclotron at gold ion energy 4.5 GeV/n and mounted two Collider storage rings with two interaction points. The status of acceleration complex NICA is under discussion. | ||

| MOPSA29 | Applied Research Stations and New Beam Transfer Lines at the NICA Accelerator Complex | 172 |
|
||
| Applied research at the NICA accelerator complex include the following areas that are under construction: single event effects testing on capsulated microchips (energy range of 150-500 MeV/n) at the Irradiation Setup for Components of Radioelectronic Apparature (ISCRA) and on decapsulated microchips (ion energy up to 3,2 MeV/n) at the Station of CHip Irradiation (SOCHI), space radiobiological research and modelling of influence of heavy charged particles on cognitive functions of the brain of small laboratory animals and primates (ener-gy range 500-1000 MeV/n) at the Setup for Investigation of Medical Biological Objects (SIMBO). Description of main systems and beam parameters at the ISCRA, SOCHI and SIMBO applied research stations is presented. The new beam transfer lines from the Nuclotron to ISCRA and SIMBO stations, and from HILAC to SOCHI station are being constructed. Description of the transfer lines layout, the magnets and diagnostic detectors, results of the beam dynamics simulations are described given. | ||

Sub Channel SOCHI of the NICA Accelerator Complex. Design Overview and Rigging at the NICA Accelerator Complex. Details of the Vacuum System | |
|
||
| As part of the tasks set, the NICA complex provides an additional channel with the main task to irradiate the microchip with beams of heavy ions with an energy of 3.2 MeV/n. The channel is based on the HILAC heavy-ion linear accelerator. The poster presents the main design features and original solutions necessary for the implementation of this project. The milestones are the special vacuum requirements and the limited space for the installation of the entire system. | ||

| WEA01 | Beam Transfer Systems of NICA Facility: from HILAC to Booster | 61 |
|
||
| New accelerator complex is being constructed by Joint Institute for Nuclear Research (Dubna, Russia) in frame of Nuclotron-based Ion Collider fAcility (NICA) project. The NICA layout includes new Booster and existing Nuclotron synchrotrons as parts of the heavy ion injection chain of the NICA Collider as well as beam transport lines which are the important link for the whole accelerator facility. Designs and current status of beam transfer systems in the beginning part of the NICA complex, which are partially commissioned, are presented in this paper. | ||

| WEA02 | Acceleration the Beams of He⁺ and Fe14+ Ions by HILAC and its Injection into NICA Booster in its Second Run | 65 |
|
||
| Injector of NICA accelerating facility based on the Heavy Ion Linear Accelerator (HILAC) is aimed to inject the heavy ions having atomic number A~200 and ratio A/Z - 6.25 produced by ESIS ion source accelerated up to the 3.2 MeV for the injection into superconducting synchrotron (SC) Booster. The project output energy of HILAC was verified on commissioning in 2018 using the beams of carbon ions produced with the Laser Ion Source and having ratio A/Z=6 that is close to the project one. Beams of He1+ ions were injected into Booster in its first run and accelerated in 2020. In 2021 ions of Fe14+ produced with the LIS were injected and accelerated up to 200 MeV/u. Beam formation of Fe ions and perspectives of using LIS for the production the ions with high atomic mass A and ratio A/Z matching to HILAC input parameters are described. | ||

Features of Reaching the Operating Vacuum in the Accelerators of the NICA Project | |
|
||
| The heavy ion NICA collider has three types of the vacuum volumes: insulating vacuum volume of superconducting magnet lattice; the cold beam pipe inside SC-magnets with operating temperature from 4.2 K to 80 K; the warm beam volume at the room temperature inside the insertion and experimental regions with RF stations, beam cooling station, diagnostic equipment and etc. The vacuum requirements, design of three vacuum systems, problems and paths of their decision for achievement ultra-high vacuum are described. | ||
