THPSC028	Switching Network Units for High Currents and Voltages or Plasma Applications	plasma, operation, controls, solenoid	603

	OCEM and ENEA gained a wide experience in the design and experimental characterization of fast and accurate switching systems for high DC currents, as required to supply magnets and superconductors. The exploited idea consists in inserting an electronic switch in parallel to a light electromechanical switch in air to combine the benefits of both devices. The electronic switch is turned on and off to support the electromechanical commutations limiting their jitter and the arcs that would reduce the system lifetime. During the already performed tests, DC currents up to 20 kA were diverted in less than 100 mks with good repeatability. In case of emergency, the current can be interrupted in few tens of milliseconds. A resistor can be inserted in parallel to the switch to discharge inductive loads or to produce desired overvoltages (a voltage up to 5 kV was reached in this configuration). Specific circuits were designed to preserve the components from transient voltage overshoots. This switching system is expected to work for 10000 operations without major maintenance. The developed solutions may be extended to many relevant applications as particle accelerators and HVDC networks.

	VEPP-5 injection complex is being put into operation as beam source of VEPP-2000 and VEPP-4 colliders at the end of 2016. Its control system is being upgraded in order to reliably work with beam users and increase its manageability computer infrastructure was reconsidered to provide high availability and flexibility through virtualization of control servers. The paper presents architecture and implementation of complex computer infrastructure. A control software set based on CXv4, EPICS and VCAS frameworks under operating system Linux deals with a set of CAN, CAMAC and Ethernet specialized hardware. The software and hardware architecture and implementation is described.
