Medium energy physics research on hypernuclear spectroscopy and muon catalyzed fusion will be performed. The hypernuclear studies will be carried out as part of the CEBAF Hall C and Hypernuclear Spectroscopy System (HNSS) collaboration. The HNSS Phase I and II is a fully approved CEBAF experiment to measure photo- and electroproduction of hypernuclei. Ongoing work in muon catalyzed fusion will continue in connection with an approved TRIUMF and Vienna. At CEBAF, responsibilities include: design review of the SOS spectrometer particle identification system, construction of the electron spectrometer's scintillator hodoscope and alignment hardware, and participating in the design of a trigger method to correlate electron-arm information with the Kaon-arm, producing an efficient hypernucleus trigger at an acceptable rate. Also, a prototype beam intensity and position monitor for Hall C, based on a commercial SQUID magnetometer will be tested. For work at TRIUMF large area, cryo-capable silicon diodes will be produced for detection of stopping charged fusion products from muon catalyzed fusion in layered frozen hydrogen targets. ***

将开展超核谱学和μ子催化聚变的中能物理研究。 超核研究将作为CEBAF Hall C和超核光谱系统（HNSS）合作的一部分进行。 HNSS第一和第二阶段是一个完全批准的CEBAF实验，用于测量超核的光和电产生。 目前在μ子催化聚变方面的工作将结合已获批准的TRIUMF和维也纳继续进行。 在CEBAF，职责包括：SOS谱仪粒子识别系统的设计审查，电子谱仪的闪烁体hodoscope和校准硬件的建设，并参与设计一个触发方法，使电子臂信息与K介子臂相关联，以可接受的速度产生有效的超核触发。 此外，还将测试基于商用SQUID磁力计的C厅射束强度和位置监测器原型。 对于TRIUMF大面积的工作，将生产具有低温能力的硅二极管，用于检测分层冷冻氢靶中μ子催化聚变产生的带电聚变产物。 ***
