摘    要:兰州重离子加速器冷却储存环工程 (HIRFL CSR)主环和实验环上带电粒子束流强度的测量和监视拟由环型束流变压器实现 .通过对各种磁芯性能的分析和比较 ,束流变压器磁芯材料最终采用环形高磁导率超微晶合金 ,可测量束流脉冲的频率范围为 0 .2 - 2MHz .选择低噪声放大器将感应信号适当放大 ,可以实现对最小流强为 1μA束流的测量. The intensity of a pulsed beam of charged particles in the Cooling Storage Ring Project of Heavy Ion Research Facility in Lanzhou (HIRFL-CSR) will be measured with a toroidal current transformer. By comparing and analyzing the properties of kinds of magnetic cores, a strip wound toroidal core is adopted, which is made of a high-permeability alloy and can measure a pulsed beam with frequency range of 0.2 to 2 MHz. The permeability of Fe-based nanocrystalline alloy varying with frequency is measured...

Abstract:The intensity of a pulsed beam of charged particles in the Cooling Storage Ring Project of Heavy Ion Research Facility in Lanzhou (HIRFL-CSR) will be measured with a toroidal current transformer. By comparing and analyzing the properties of kinds of magnetic cores, a strip wound toroidal core is adopted, which is made of a high-permeability alloy and can measure a pulsed beam with frequency range of 0.2 to 2 MHz. The permeability of Fe-based nanocrystalline alloy varying with frequency is measured...
