- ПубликацияТолько метаданныеUltimate energy recovery from spent relativistic electron beam in energy recovery linear accelerators(2020) Konoplev, I. V.; Marhauser, F.; Shashkov, Y.; Bulygin, A.; Gusarova, M. A.; Шашков, Ярослав Васильевич; Гусарова, Мария Александровна© 2020 authors. Published by the American Physical Society.

Further distribution of this work must maintain attribution to the author(s) and the published article's title, journal citation, and DOI.Energy recovery linear accelerators (ERLs) rely upon single-axis superconducting radio frequency (SRF) cavities to be an efficient source of relativistic electrons for high energy and nuclear physics. SRF cavities are also considered relevant for next-generation photon factories and radio-isotope production facilities. The ultimate energy recovery capability for the accelerator would be the ability to operate with a sufficiently spent beam and decrease the energy of the beam before the beam dump to a value lower than the beam injection energy. This is especially important for high current accelerators, where the beam injection energy could be as high as several MeV, and systems where partial beam loss can be expected. The efficient operation of energy recovery in linear accelerators is adversely affected by the typical degradation of the beam quality and current loss. This hinders the application of the ERLs in research and industry, and enabling the use of spent (partially lost current), degraded beams should broaden their application. We suggest that the use of the asymmetric operating mode observed in the dual-axis asymmetric cavities will enable such ultimate capabilities. We discuss the advantages of the application of fields of different amplitude along the cavity accelerating and decelerating axes and demonstrate that the fields can be tuned separately in each axis of the dual-axis cavity. The design of such a cavity and ways to optimize the energy recovery of a spent electron beam by tuning the dual-axis asymmetric SRF cavity are discussed.

- ПубликацияТолько метаданныеControl of electromagnetic properties during prototyping, fabrication and operation of low-beta 325 MHz half-wave resonators(2021) Bychanok, D.; Sukhotski, A.; Huseu, S.; Vasilevich, E.; Gusarova, M.; Lalayan, M.; Polozov, S.; Гусарова, Мария Александровна; Лалаян, Михаил Владимирович; Полозов, Сергей МарковичThe general steps for the fabrication of a copper prototype of 325 MHz coaxial half-wave resonator (HWR) with beta = 0.21 are presented and discussed in this work. The main features for the control of the electromagnetic properties during the manufacturing process of HWR are described in detail. The resonant frequency sensitivity to the accelerating gap and to the cavity height were experimentally estimated. Bead-pull measurements were performed and the electric field distribution along the beam axis of the manufactured cavity was estimated. The features of the cavity's response in the critical coupling regime are analyzed. The experimental concept of a slow frequency tuning system (FTS) based on the moving plungers is proposed and tested. The tuning sensibility is experimentally estimated. The measured results agree with the simulations quite well, and the sensitivity for a single plunger configuration Delta f/Delta L = +13 kHz mm(-1) is achieved. The dynamic properties and operation algorithm of the FTS are studied and experimentally investigated.

All rights reserved.Design of the cryomodule prototype for testing low-beta 325 MHz half-wave cavities is currently in the process at INP BSU. The cryomodule allows performing intermediate vacuum-, temperature-, and rf-tests during the fabrication of half-wave resonators. The irst experimental results of cryomodule cooling down to liquid nitrogen temperatures are presented and discussed. The pressure and temperature control allows us to estimate the main cooling/heating characteristics of the cryostat at diferent operation stages. The presented test cryomodule will be used for further development and production of superconductive niobium cavities for the Nuclotron-based Ion Collider fAcility (NICA) injector.
- ПубликацияТолько метаданныеLinaccalc: Software for accelerating structure characteristics simulation based on equivalent circuit method(2021) Matsievskiy, S. V.; Kaminskii, V. I.; Gorchakov, A. A.; Lalayan, M. V.; Gusarova, M. A.; Sobenin, N. P.; Мациевский, Сергей Викторович; Каминский, Владимир Ильич; Лалаян, Михаил Владимирович; Гусарова, Мария Александровна© 2021, Institute for Problems in Mechanical Engineering, Russian Academy of Sciences. All rights reserved.Nowadays design of accelerating structures is almost exclusively done using 2.5D and 3D codes based on finite elements method. Equivalent circuit method is fre-quently considered limited and inconvenient to use in real-life projects. However, low resource requirements make this method attractive for wide range sweep calcu-lations. This paper describes LinacCalc application — a user friendly accelerating structure simulation software based on the equivalent circuit method. It allows cal-culating characteristics of the accelerating sections with large number of cells in short time on machines with moderate amount of computational power. Core application modules are validated by comparing calculation results with ones obtained by a conventional finite ele-ment method based programs.

All rights reserved.The new linac for light ion beam injection is under development at MEPhI. Such linac was proposed for acceleration of 7.5 MeV/nucleon ion beam with A/Z=1-3.5 and current up to 5 mA for proton and 0.4 pmA for light ions. The linac general layout will include two types of ion sources: ECR ion source for proton and He ions and laser ion source for ions form Li to O. Following the LEBT ions will be bunched and accelerated to the final energy using RFQ section and 14 IH-cavities. These IH-cavities will be identical (divided into two groups) and independently phased. All cavities will operate on 81.25 MHz. Results of the beam dynamics simulations and the cavities design will be presented in the report.
