ATLAS粒子物理探测器用金刚石胶的热导率
Thermal conductivity of diamond-loaded glues for the ATLAS particle physics detector
摘要：
ATLAS实验是位于瑞士日内瓦的欧洲核子研究中心实验室的大型强子对撞机（LHC）上的两个大型通用粒子探测器之一。自2009年12月以来，ATLAS一直在收集质子碰撞的数据，以研究早期宇宙中存在的条件和质量的起源，以及基础粒子物理学中的其他主题。在LHC运行的最初几年里，ATLAS探测器的最内层将暴露在最大的辐射中。特别地，最靠近束管的层，B层，将由于增加的辐射而随时间退化。为了弥补其退化，它将在2016年左右被可插入B层（IBL）取代。IBL的设计和研发正在进行中，因为希望使用最新的技术来构建这个新的子探测器层。感兴趣的一个主题是在IBL的构造中使用更多的导热胶，以促进从探测器的散热。在本文中，测量和使用高导热胶，特别是那些金刚石加载，将进行讨论。应用改进的瞬态平面源导热系数测量技术，对不同温度范围内的胶体进行了测量。
英文摘要：
The ATLAS experiment is one of two large general-purpose particle detectors at the Large Hadron Collider (LHC) at the CERN laboratory in Geneva, Switzerland. ATLAS has been collecting data from the collisions of protons since December 2009, in order to investigate the conditions that existed during the early Universe and the origins of mass, and other topics in fundamental particle physics. The innermost layers of the ATLAS detector will be exposed to the most radiation over the first few years of operation at the LHC. In particular, the layer closest to the beam pipe, the B-layer, will degrade over time due to the added radiation. To compensate for its degradation, it will be replaced with an Insertable B-Layer (IBL) around 2016. The design of and R&D for the IBL is ongoing, as the hope is to use the most current technologies in the building of this new sub-detector layer. One topic of interest is the use of more thermally conductive glues in the construction of the IBL, in order to facilitate in the dissipation of heat from the detector. In this paper the measurement and use of highly thermally conductive glues, in particular those that are diamond-loaded, will be discussed. The modified transient plane source technique for thermal conductivity is applied in characterizing the glues across a wide temperature range.
