A particle detector at a collider experiment works fairly like a big digital camera, developing "pictures" of the particles coming out of the collision through the signals that they generate in the sensitive material. Like in a digital camera, an ultimate detector resolution is needed to be able to look at the fine details of these particle interactions. Indeed, our particle physics main theory is so finely developed, that we will need high resolution to spot tiny deviations from what the theory predicts, improving our knowledge.A new concept of particle detector, a dual-readout calorimeter, promises to yield unprecedented resolution for the energy measurement of a very broad class of particles, known as hadrons. This energy resolution will allow us to distinguish different manifestations of, e.g., the Higgs boson, greatly increasing the knowledge we have about it, thus our ability to study it.This project focuses on the development of a lab infrastructure to be able to contribute to key R&D for this innovative particle detector. In particular, it will study how much light the optical elements of the calorimeter can trap, and how well the timing of the energy deposits can be determined.

对撞机实验的粒子探测器的工作方式与大型数码相机的工作效果相当，从而通过它们在敏感材料中产生的信号形成了粒子的“图片”。像在数码摄像头中一样，需要终极检测器分辨率来查看这些粒子相互作用的细节。的确，我们的粒子物理主要理论是如此精致，以至于我们将需要高分辨率来发现与理论预测的那样，改善我们的知识。粒子探测器的新概念，一种双读热量量热计，有望产生前所未有的分辨率，以实现非常广泛的粒子的能量测量，众所周知的hastrons。这种能源分辨率将使我们能够区分Higgs Boson的不同表现形式，从而大大提高了我们对其的知识，因此我们进行研究的能力。该项目着重于实验室基础设施的发展，以便能够为这项创新粒子探测器为关键的R＆D贡献。特别是，它将研究量热仪的光学元素可以捕获多少光，以及能量沉积的时机能够确定的时间。
