9314783 Cameron印第安纳大学回旋加速器设施是一个国家用户设施，用于核科学研究。这笔资金用于国际自然保护基金会的运作，支持其用户计划，印第安纳大学工作人员的研究，以及核科学，加速器物理和相关领域研究生的培训。IUCF的设备包括一个200 MeV的回旋加速器和一个500 MeV的电子束冷却加速同步加速器。利用提取的回旋加速器束在多个实验区进行实验，并在冷却器环中使用超薄内靶。偏振光束可用于所有区域，偏振气体目标可用于冷却器环。一种新的高强度极化离子源（HIPIOS）将提供20倍的光束电流增加。可以使用各种各样的探测器，包括磁谱仪，中子飞行时间系统，反冲探测器，大型闪烁体和线室阵列。K600光谱仪配有焦平面偏振计和束摇摆中子探测系统，将用于广泛的自旋转移反应，旨在研究有效的核子-核子相互作用。将在阈值介子产生、少体反应、核子-核子散射、核子-核子反应等方面进行研究，所有这些都是为了更好地理解原子核的强子亚结构、介子自由度的潜在作用以及基本对称性的测试。研究生和本科生被整合到IUCF研究的各个方面，包括仪器开发，他们的培训是IUCF活动的一个突出方面。

9314783 Cameron The Indiana University Cyclotron Facility is a national user facility for research in nuclear science. This grant provides funds for the operation of IUCF, for support of its user program, for the research of the Indiana University staff, and for the training of graduate students in nuclear science, accelerator physics, and related fields. The facilities at IUCF include a 200 MeV cyclotron and a 500 MeV booster synchrotron with electron beam cooling. Experiments are possible with the extracted cyclotron beam in several experimental areas, and using ultra-thin internal targets in the Cooler ring. Polarized beams are available in all areas, and polarized gas targets can be used in the Cooler ring. A new high-intensity polarized ion source (HIPIOS) will provide a twenty-fold increase in beam currents. A wide variety of detectors can be used, including magnetic spectrometers, neutron time-of-flight systems, recoil detector, and large scintillator and wire chamber arrays. The K600 spectrometer with focal plane polarimeter and Beam Swinger neutron detection system will be used in a broad range of spin transfer reactions aimed at studying effective nucleon-nucleon interactions. Studies will be carried out in threshold meson production, few-body reactions, nucleon-nucleon scattering, nucleon-nucleus reactions, all directed towards improved understanding of the hadronic substructure of nuclei, the underlying role of meson degrees of freedom, and tests of fundamental symmetries. Graduate students and undergraduates are integrated into all aspects of IUCF research, including instrumentation development, and their training is a prominent aspect of IUCF activities.
