Dr. Giovanetti and his undergraduate students from James Madison University (JMU) are participating in the construction, and ultimately the usage, of the CEBAF Large Acceptance Spectrometer (CLAS) at the newly operating Continuous Electron Beam Accelerator Facility (CEBAF) in Newport News, VA. Presently the group is constructing and testing a system to monitor the gains of a major detector system for CLAS (1000 photomultiplier tubes). The CLAS detector should begin to operate next year, and the JMU group will participate in experiments to study the quark gluon structure of baryons. This program provides excellent opportunities for undergraduate students to participate in forefront research. The close proximity of JMU to CEBAF also provides the students rather extensive involvement in the research by permitting a number of visits to the lab in a cost effective manner.

Giovanetti博士和他来自詹姆斯麦迪逊大学（JMU）的本科生正在弗吉尼亚州纽波特纽斯新运行的连续电子束加速器设施（CEBAF）中参与CEBAF大型接受光谱仪（CLAS）的建造和最终使用。目前，该小组正在建造和测试一个系统，以监测CLAS（1000个光电倍增管）主要探测器系统的增益。CLAS探测器应该在明年开始运行，JMU小组将参与实验，研究重子的夸克胶子结构。该计划为本科生提供了参与前沿研究的绝佳机会。JMU靠近CEBAF也为学生提供了相当广泛的参与研究，允许以具有成本效益的方式访问实验室。
