Instrumentation, Field Network and Process Automation for the Cryogenic System of the LHC Test String
摘要：
CERN现在正在建立String 2，一个LHC弧的规则单元的全尺寸原型。它是由两个四极，六个偶极磁铁，和一个单独的低温分配线（QRL）的供应和回收的冷冻剂。一个带有多达38根高温超导（HTS）引线的馈电盒（DFB）为磁体供电。大约700个传感器和执行器分布在四个Profibus DP和两个Profibus PA现场总线上。过程自动化由两个控制器处理，运行126个闭环控制回路（CCL）。本文介绍了低温控制系统、相关仪表及其调试。
英文摘要：
CERN is now setting up String 2, a full-size prototype of a regular cell of the LHC arc. It is composed of two quadrupole, six dipole magnets, and a separate cryogenic distribution line (QRL) for the supply and recovery of the cryogen. An electrical feed box (DFB), with up to 38 High Temperature Superconducting (HTS) leads, powers the magnets. About 700 sensors and actuators are distributed along four Profibus DP and two Profibus PA field buses. The process automation is handled by two controllers, running 126 Closed Control Loops (CCL). This paper describes the cryogenic control system, associated instrumentation, and their commissioning.
