The LHC ACS RF system is composed of 16 superconducting cavities, eight per ring, housed in a total of four cryomodules each containing four cavities. Each cavity is powered by a 300 kW klystron. The ACS RF power control system is based on industrial programmable logic controllers (PLCs), with additional fast RF interlock protection systems. The Low Level RF (LLRF) is implemented in VME crates. Operational performance and reliability are described. A full set of user interfaces, both for experts and operators has been developed, with user feedback and maintenance issues as key points. Operational experience with the full RF chain, including the low level system, the beam control, the synchronization system and optical fibers distribution is presented. Last but not least overall performance and reliability based on experience with first beam are reviewed and perspectives for future improvement outlined.

Leading-edge LSI products with 40nm logic technology node and beyond are facing the issue of how higher memory bandwidth is reconciled with lower power consumption. Chip stacking of a logic chip on a large-scale DRAM chip, interconnected with each other by fine-pitch bumps, provides a solution to realize a power efficient SiP (System in Package). In this paper, the successful process integration of 10μm pitch Cu redistribution wiring and 40μm pitch SnCu micro-bumping on 300mm wafers, together with chip-on-chip (CoC) joining, has been described in an effort to relinquish embedded DRAM (eDRAM) SoC (System on Chip).
In this paper we focus on improving the tests coverage of a Schneider Electric protection device using system modeling and simulation techniques. Our approach consists of modeling the device in its operating environme...
