Christian Mayoux passed away on the 29th of October, 2020, at the age of 84, in Muret, a small town near Toulouse in the south of France, where he used to live since ten years. Christian was born in Pamiers, France, in 1936. He received the Doctorate degree (PhD) in 1961 from the University of Toulouse from which Paul Sabatier University was established in 1969. From 1963 to 1966, he was lecturer at the University before joining the French National Center for Scientific Research (CNRS) and the new born “Laboratoire de Genie Electrique de Toulouse” (LGET). The new lab was under the supervision of Professor R. Lacoste and focused its research on dielectrics and electrical insulation in the context of Electrical Engineering. The LGET researchers were fighting within the French research landscape to launch and organize the new domain of “engineering sciences”. Christian Mayoux investigated the effects of electrical discharges on dielectric surfaces, trying to understand the chemical and physical processes at play at different stages of the interaction. Transformation of the surface for short interaction time with the emergence of specific surface properties, but also surface degradation for longer interaction time, with deleterious effects for the material withstanding were put forward. Following this, a new approach where the surface of a polymer was exposed to different species -electrons, ions, metastables, UV, etc. was brought about with the objective to understand the individual and synergetic effects of each of the energy sources present in a partial discharge. Christian was quickly recognized by the international community for this pioneering work then developed internationally. Later on, starting in 1976, he began to focus on electrical treeing phenomena, and later on water treeing, following at the same time the ideas that emerged from his initial work on partial discharges. On top of that, Christian Mayoux was at the origin of several research areas that are still very active in LAPLACE (the successor of LGET), among them the dielectric barrier discharges at atmospheric pressure that become homogeneous under given circumstances, the luminescence phenomena occurring when an electric field is applied to a dielectric, or the mechanical deformation of a polymer under high electric field. Christian Mayoux received many invitations for giving invited lectures either at international conferences or during seminars. He was awarded the Whitehead Memorial Lecture at the Conference on Electrical Insulation and Dielectric Phenomena (CEIDP) in 2000.

纪念 Christian Mayoux 1936–2020

Christian Mayoux 于 2020 年 10 月 29 日在法国南部图卢兹附近的小镇 Muret 去世，享年 84 岁，他在那里生活了十年。Christian 1936 年出生于法国帕米尔。1961 年获得图卢兹大学博士学位（PhD），1969 年保罗萨巴蒂尔大学成立。1963 年至 1966 年，他在该大学任讲师，然后加入图卢兹大学。法国国家科学研究中心 (CNRS) 和新生的“图卢兹精灵电力实验室”(LGET)。新实验室在 R. Lacoste 教授的监督下，专注于电气工程背景下的电介质和电绝缘研究。LGET 研究人员正在法国研究领域内奋战，以启动和组织“工程科学”的新领域。Christian Mayoux 研究了放电对电介质表面的影响，试图了解在相互作用的不同阶段起作用的化学和物理过程。提出了随着特定表面性质的出现而在较短的相互作用时间内表面发生转变，以及较长相互作用时间的表面降解，对材料耐受性产生不利影响。在此之后，提出了一种将聚合物表面暴露于不同种类（电子、离子、亚稳态、紫外线等）的新方法，目的是了解存在于聚合物中的每种能源的单独和协同效应。局部放电。克里斯蒂安的这项开创性工作很快得到国际社会的认可，随后在国际上得到了发展。后来，从 1976 年开始，他开始关注电树现象，后来又关注水树，同时遵循他最初关于局部放电的工作中出现的想法。最重要的是，Christian Mayoux 是几个在 LAPLACE（LGET 的继任者）仍然非常活跃的研究领域的起源，其中在大气压下的介质阻挡放电在特定情况下变得均匀，发光现象发生在电场施加到电介质上，或聚合物在高电场下的机械变形。Christian Mayoux 曾多次受邀在国际会议或研讨会上作特邀演讲。他于 2000 年在电绝缘和介电现象会议 (CEIDP) 上获得怀特黑德纪念演讲奖。
