MRI-Consortium: Development of the Forward Tagger for the CLAS12 Detector at Jefferson Lab

这笔核磁共振资金将帮助支持由国际科学家合作建造的粒子探测器的开发。使用这种探测器的实验的主要目标是寻找新的和奇异的物质形式。普通物质是由质子、中子和电子组成的。许多其他类型的粒子是已知的，但根据被称为量子色动力学(QCD)的强力理论的理论模型，预测存在一些短暂的粒子。当高能光子撞击质子靶时，会产生许多粒子，其中一些可能是预测的奇异粒子，如胶球或混合介子。在开发这种仪器的过程中，物理学家对学生进行高科技设备和电子设备的使用培训。其中一些学生继续开发这项技术的新用途，例如许多医院使用的诊断设备，包括MRI、CAT和PET扫描仪。训练有素的劳动力对经济的影响是有据可查的。该设备的开发将培养具有当今市场所需的高科技技能的学生，同时增加我们对QCD的理解。

This MRI grant will help support the development of a particle detector being built by an international collaboration of scientists. The primary objective for the experiment using this detector is the search for new and exotic forms of matter. Regular matter is made from protons, neutrons and electrons. Many other types of particles are known, but some short-lived particles are predicted to exist from theoretical models of the theory of the strong force, called quantum chromodynamics (QCD). When high-energy photons strike a proton target, many particles are produced, and some of these may be the predicted exotic particles such as glueballs or hybrid mesons. In the process of developing this instrumentation, physicists train students in the use of high-technology equipment and electronics. Some of these students go on to develop new uses of the technology, such as the diagnostic equipment used in many hospitals, including MRI, CAT and PET scanners. The economic impact of a highly-trained workforce is well-documented. The development of this equipment will train students with high technology skills that are needed in today's marketplace, while adding to our understanding of QCD.
