An experiment to study threshold pion production in proton-proton collisions will be conducted at the IUCF Cooler. The equipment required for this experiment (including a new ring magnet and a new two-arm detector system) has been built and tested at the University of Pittsburgh and IUCF. The new magnet will become a permanent part of the Cooler ring. The experiment measuring differential cross sections and analyzing powers will run during 1991. A followup experiment measuring the complete scattering matrix using a polarized beam and target is proposed here. Development work for an approved CEBAF experiment in eta electroproduction from the proton will be carried out. The Pittsburgh effort is in building the drift chamber array that surrounds the target within the CEBAF Large Acceptance Spectrometer, an effort requiring significant planning and testing.

将在IUCF冷却器上进行质子-质子碰撞中阈值介子产生的实验研究。这项实验所需的设备（包括一个新的环形磁铁和一个新的双臂探测器系统）已经在匹兹堡大学和国际自然保护基金会建造和测试。新的磁铁将成为冷却器环的永久部分。测定微分截面和分析功率的实验将于1991年进行。本文提出了一种利用偏振光束和目标测量完全散射矩阵的后续实验。将进行经批准的CEBAF质子电生产实验的开发工作。匹兹堡的工作是在CEBAF大型验收光谱仪中建立围绕目标的漂移室阵列，这项工作需要大量的规划和测试。
