本文扼要地介绍了稳态超导磁镜装置的概貌。给出了在1977——1982年期间装置真空系统、电气系统、粒子束物理对中、离子注入器、碳弧中性化室和捕集室低温超导系统的局部调试和装置联合工程调试的结果。通过对装置的局部调试和联调,达到了第一期工程指标。离子源能量100keV,引出总离子流0.7A,H_2~+束在透镜入口达120mA,注入到捕集室中心为26mA,最高注入中性束等效流强为7.2mA。捕集室超导磁体在4.2K液氦条件下实现超导9h,当磁体升流133A时,捕集室中心磁场达21.7kGs。采用了冷凝吸附抽气技术,捕集室静真空度最高达4.8×10~(-9)Torr,注束时动真空度为3.5×10~(-8)Torr。
This article gives a brief overview of the steady-state superconducting magnetic mirror device. The local commissioning and commissioning of devices for vacuum system, electrical system, particle beam physics centering, ion implanter, carbon arc neutralization chamber and trap cryogenic superconducting system during 1977-1982 are given result. Through the local commissioning of the device and joint adjustment, the first phase of the project reached the target. The ion source energy of 100keV, leads to a total ion current of 0.7A, H_2 ~ + beam entrance at the lens up to 120mA, into the capture chamber center to 26mA, the maximum injected neutral beam equivalent flow 7.2mA. Trapping chamber superconducting magnet superconducting in 4.2K liquid helium conditions 9h, when the magnet up 133A, the capture chamber center magnetic field of 21.7kGs. Adopting the technology of condensing adsorption and desorption, the static vacuum of trapping chamber is up to 4.8 × 10 ~ (-9) Torr and the dynamic vacuum degree is 3.5 × 10 ~ (-8) Torr.
