Abstract

The creation of a new multipurpose isochronous cyclotron DC140 is being carried out at the Flerov Laboratory of Nuclear Reactions, Joint Institute for Nuclear Research. The DC140 cyclotron is intended for microchip testing on radiation resistance, the production of track pore membranes, and applied physics. The cyclotron will accelerate heavy ions with mass-to-charge ratio A/Z ranging from 5 to 8 up to fixed energies of 2.1 and 4.8 MeV per nucleon. The new cyclotron DC140 will be created as a deep reconstruction of the DC72 cyclotron. In particular, it is supposed to adapt the DC72 electromagnet for obtaining new acceleration regimes. In this paper, the main parameters of the DC72 and DC140 magnetic systems, the results of calculations and measurements of the magnetic field, and estimations of the possibility of formation of new acceleration regimes with minimal changes in the DC72 magnetic system are presented.

基于DC72电磁铁的新型DC140同步回旋加速器的磁系统

摘要

联合核科学研究所的弗莱罗夫核反应实验室正在研制一种新的多用途同步回旋加速器DC140。DC140回旋加速器旨在用于抗辐射，跟踪孔膜的生产以及应用物理学的微芯片测试。回旋加速器将以质荷比A / Z从5到8加速重离子，直至每个核子的固定能量分别为2.1和4.8 MeV。新型回旋加速器DC140将作为DC72回旋加速器的深度改造而创建。特别是，应该使DC72电磁体适应以获得新的加速状态。本文介绍了DC72和DC140磁系统的主要参数，磁场的计算和测量结果，
