Psi回旋加速器磁体电源、控制和现场总线的更换
Replacement of Magnet Power Supplies, Control and Field-Bus for the Psi Cyclotron Accelerators
摘要：
PSI加速器复合体中的磁体电源及其控制和现场总线都是旧的。有些部件已经使用了30多年。为了保证进一步的维护和满足更苛刻的2 mA光束操作规范，必须更换它们。将使用为SLS开发的开关电源。这意味着对加速器控制系统的一部分进行了重大重新设计，该系统现在基于CAMAC，ROAD-C和其他内部开发的硬件，包括机器保护系统。新设置的修改控制将基于VME或CAMAC，并具有用于机器保护系统功能的专用处理器。
英文摘要：
Magnet power supplies in the PSI accelerator complex with their control and field-bus are old. Some components are more then 30 years old. To guarantee further maintenance and to meet the more demanding specifications for operation with the 2mA beam, they have to be replaced. The switched power supplies, developed for SLS, will be used. This implies a major redesign of part of the accelerator control system, which is now based on CAMAC, ROAD-C and other in house developed hardware including the machine protection system. The modified control for the new set-up will be based on VME and alternatively CAMAC, with dedicated processors for the functionality of the machine protection system.
