Compact three-dimensional silicon termination solutions for high voltage SOI SuperJunction

This paper demonstrates and discusses novel "three dimensional" silicon based junction isolation/termination solutions suitable for high density ultra-low-resistance Lateral Super-Junction structures. The proposed designs are both compact and effective in safely distributing the electrostatic potential away from the active device area. The designs are based on the utilization of existing layers in the device fabrication line, hence resulting in no extra complexity or cost increase. The study/demonstration is done through extensive experimental measurements and numerical simulations. © 2012 IEEE.

Experimental study of the high-voltage breakdown and simulations for the RFQ cooler and buncher RFQ1L

The RFQ cooler and buncher RFQ1L is one of the key parts of the being-built super-heavy nuclide research spectrometer. In order to understand the high-voltage breakdown phenomenon, the voltages between electrodes have been measured. In addition, more extensive simulations have been performed for better understanding and optimizing the RFQ1L work points.

高电压锯齿波聚束器的设计研制；Theoretical Calculation of Sawtooth Wave Buncher with High Voltage

近些年来,使用锯齿波直接形成的方法建造非谐振型聚束器在国内及国际均得到了广泛的应用。由于电子技术及机械加工工艺的飞速发展和更高功率电子管的出现,可以设计出更高指标的聚束器,进而可以有效提高束线的匹配效率及运行稳定度。对兰州重离子加速器源束线新的高电压锯齿波聚束器的研制进行了详细阐述,由于该聚束器具有目前国际同类型设备中最高的电压、频率以及相对苛刻的现场条件限制,故还对设计中所涉及的工程实施方案进行了有效补充和完善。

Risk versus National Pride. Conflicting discourses over the construction of a High Voltage Power Station in the Athens Metropolitan Area for demands of the 2004 Olympics

This paper first explores the conflictual discourses employed by government agencies, citizens’ initiatives, and environmental organizations over the construction of a High Voltage Power Station (KYT) for demands of the 2004 Olympic Games, as presented in media reports and movement literature over a period of one year. Having in mind recent criticisms targeting the lack of empirical evidence in Ulrich Beck’s risk theorization, this exploration is of distinct importance. Secondly, it takes into account that both the defensive character of societal action and mistrust to expert authorities have been confirmed as prevalent characteristics of both the Greek and the general risk social context. The paper attempts to re-evaluate and/or complement existing perspectives of societal activism in general and environmental mobilizations in particular within the confines of the Greek social context. As a tentative conclusion, it is suggested that the risk perspective offers a novel prism for the examination of societal activism without confining it to the characteristics of individual national contexts.
