ALICE MasterClasses和新型粒子治疗MasterClass的新发展
New developments for ALICE MasterClasses and the new Particle Therapy MasterClass
摘要：
国际大师班（IMC）是国际粒子物理学外展小组（IPPOG）的一项外展活动，15年来一直在为学童提供尖端的粒子物理学研究。所有四个大型强子对撞机实验都参加了这次活动，包括ALICE，这是一个为研究重离子碰撞而优化的实验。重离子物理学正在积极地为IMC做出贡献，其新的发展包括实验测量以及社会应用，例如用离子治疗癌症。特别是，ALICE提供了三个MC测量相关的主要观测值用于表征所产生的夸克-胶子等离子体的属性。从历史上看，这些MC测量是独立开发的，继承了第一个，由几个ALICE小组。由于所有这些都是基于ROOT EVE包，因此开展了一个项目，将它们纳入一个共同的框架。ALICE现在提供了一个简单易用的应用程序，在Linux，MacOS下编译，并首次在Windows下编译。然后，根据目前IPPOG的目标，增加IMC计划的全球范围和范围，一个新开发的粒子物理学医学应用测量，粒子治疗大师班（PTMC）被引入到IMC 2020计划中。它是matRad的简化版本，matRad是一个基于MATLAB的工具包，用于计算体内剂量沉积，并允许使用不同的模式规划放射治疗，并突出离子治疗的好处。
英文摘要：
International MasterClasses (IMC), an outreach activity of the International Particle Physics Outreach Group (IPPOG), has been bringing cutting-edge particle physics research to schoolchildren for over 15 years now. All four LHC experiments participate in the event, including ALICE, the experiment optimised for the study of heavy-ion collisions. Heavy-ion physics is actively contributing to IMC with new developments including experimental measurements but also applications for society, such as treatment of cancer with ions. In particular, ALICE provides three MC measurements related to the main observables used to characterize the properties of the produced Quark-Gluon Plasma. Historically, those MC measurements were developed independently, inheriting from the first one, by several ALICE groups. Since all of them are based on the ROOT EVE package, a project to integrate them into a common framework was undertaken. ALICE delivers now a single and easy-to-use application, compiled under Linux, MacOS, and, for the first time, Windows. Then, in line with current IPPOG goals to increase the global reach and scope of the IMC programme a newly developed measurement on medical applications of particle physics, the Particle Therapy MasterClass (PTMC) was introduced in the IMC2020 programme. It is a simplified version of matRad, a MATLAB-based toolkit for calculation of dose deposition in the body and allows for planning of radiotherapy using different modalities and highlighting the benefits of treatment with ions.
