Abstract
Inside the new laboratory for the development of neutral beam injectors PRIMA (Padova Research on Injector Megavolt Accelerated), whose construction was entrusted to the Consorzio RFX Padova, two experimental plants are in advanced installation phase; MITICA (Megavolt ITER Injector & Concept Advancement) and SPIDER (Source for Production of Ion of Deuterium Extracted from Rf plasma). They aim at studying new systems for the production of neutral particles accelerated to high energy to heat the plasma. Both the two experiments are formed of big chambers kept in high vacuum by a pumping system, housing a negative Ion source filled with process gas for the production of a high energy beam. The two experiments are managed, with respect to the pumping, distribution and gas injection systems, by a system called GVS, that provides also the control and data acquisition. The PRIMA Gas System (PRIMA GS) is split into three plant units: SPIDER PU, MITICA PU and GSD Shared PU, dealing with SPIDER, MITICA and shared equipment (Gas Storage and Distribution, mainly) respectively; each unit consists of a slow controller (Siemens PLC Simatic S7-400FH) with Profibus distributed I/O. The main functions of the GVS are to provide: the vacuum inside the SPIDER and MITICA vessel, the D2/H2 gas injection during the pulse by programmed waveform, the pumping of the gas released during regeneration phase of cryogenic pumps. The SPIDER and MITICA GVS comprise multiple subsystems, such as: Forevacuum Pump System, TurboPumps System, Source Gas Injection System, Vacuum sensors system, CryoPumps System (only for SPIDER), Neutralizer Gas Injection System (only for MITICA). The PRIMA GSD manages the storage and distribution of all gases necessary to run the SPIDER and MITICA experiments. The main control of the SPIDER and MITICA experiments is made by a COntrol and Data Acquisition System (CODAS). The article describes the main elements of the vacuum pumping system, the gas distribution and injection system, and the architecture of the control system that manages the plant.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
