Best Cyclotron Systems Inc （BCSI）设计并制造了一个70 MeV的紧凑型回旋加速器，用于放射性同位素的生产和研究应用。回旋加速器是在加拿大渥太华的Best Theratronics工厂为意大利Legnaro的INFN-LNL实验室建造的。该回旋加速器具有一个外部负氢离子源，在相对的山谷中具有两个分离度的四个径向扇区，低温真空系统和在相反的线上同时抽束。光束强度为700微安，提取能量在35 - 70兆电子伏特之间。报告了客户现场的梁调试情况。回旋加速器和束流线设备已经在INFN LN Legnaro安装和调试，在进行高能束流加速之前，工厂验收测试（FAT）已经成功重复。回旋加速器配备了一个位于1 MeV半径处的低能量束流拦截探头。探头用于优化光束通过低能量光束输运（LEBT）线的输运，并表征光束注入效率和1 MeV的加速度。已经完成了高达1mev的完整表征，并报告了[1]作为FAT的一部分。梁强度和稳定性参数已确定为较好的值，如表1所示。表1:1 MeV探针的光束
Best Cyclotron Systems Inc (BCSI) has designed and manufactured a 70 MeV compact cyclotron for radioisotope production and research applications. The cyclotron has been built at the Best Theratronics facility in Ottawa, Canada for the INFN-LNL laboratory in Legnaro, Italy. The cyclotron has an external negative hydrogen ion source, four radial sectors with two separated dees in opposite valleys, cryogenic vacuum system and simultaneous beam extraction on opposite lines. The beam intensity is 700 microamperes with variable extraction energy between 35 and 70 MeV. The beam commissioning performances at the customer site are reported. BEAM COMISSIONING The cyclotron and beam line equipment has been installed and commissioned at INFN LN Legnaro and the Factory Acceptance Test (FAT) has been successfully repeated before proceeding with high energy beam acceleration. 1 MeV Acceleration The cyclotron is equipped with a low energy beam intercepting probe located at the 1 MeV radius. The probe is used to optimise the beam transport through the Low Energy Beam Transport (LEBT) line and characterise the beam injection efficiency and acceleration to 1 MeV. A complete characterisation up to 1 MeV has been done and reported [1] as part of the FAT. Beam intensity and stability parameters have been confirmed to better values as shown in Table 1.
