摘要

Rikagaku Kenkyūjo (RIKEN)重离子直线加速器通过引入新的超导直线加速器进行升级，以推进RIKEN放射性同位素束流工厂(RIBF)的超重元素合成计划。通过引入超导直线增压器SRILAC，总加速电压从采用12个室温漂移管直线增压器(dtl)的25 MV提升到39 MV。新型超导电子回旋共振离子源(SC-ECRIS)实现了束流强度的提升。SRILAC和SC-ECRIS的建设于2017财年开始。硬件安装调试完成后，2019财年末首次波束加速测试成功，2020财年开始用户波束服务。本文提供了升级及其当前性能的概述。

Superconducting Linac Booster for Super-Heavy Element Experiments at RIKEN Radioactive Isotope Beam Factory

Abstract The Rikagaku Kenkyūjo (RIKEN) heavy-ion linac was upgraded by introducing a new super-conducting linac-booster to advance the super-heavy elements synthesis program beyond nihonium at the RIKEN Radioactive Isotope Beam Factory (RIBF). The total acceleration voltage was upgraded from 25 MV with 12 room temperature drift-tube-linacs (DTLs) to 39 MV by introducing a superconducting linac booster, SRILAC. The upgrade of the beam intensity is realized by a newly constructed superconducting electron-cyclotron resonance ion source (SC-ECRIS). The construction of SRILAC and the SC-ECRIS started in FY2017. After the hardware installation and commissioning, the first beam acceleration test was successfully conducted at the end of FY2019, and user beam service was started in FY2020. This article provides an overview of the upgrade and its present performance.
