Research at the Intensity Frontier builds upon the development of High Intensity Accelerators and Storage Rings. With the increase in circulating beam currents, particularly for positively charged beams, various effects such as the rise of electron clouds become increasingly challenging. For example, the beam intensity in the Fermilab Main Injector is predicted to increase approximately four-fold for the Project-X upgrade, and electron cloud formation is expected to be a problem. The IIT group intends to measure in detail electron cloud formation in the presence of different materials and under varying beam conditions. The program of effort will involve design work to evolve the performance and variety of electron cloud measurement techniques, as well as to validate or improve electron cloud models used in numerical simulations by the scientific community. The research will be performed collaboratively with experts at Fermilab and at Argonne National Laboratory. Through this program, IIT is building a nascent graduate program in accelerator physics and materials research to support future accelerator development, with students involved in all aspects of the research, from hardware to modeling to numerical simulations.

强度前沿的研究建立在高强度加速器和存储环的发展基础上。随着循环电子束电流的增加，特别是带正电荷的电子束，电子云的上升等各种效应变得越来越具有挑战性。例如，费米实验室主注入器的光束强度预计将增加大约四倍，用于项目- x的升级，电子云的形成预计将成为一个问题。IIT小组打算在不同材料存在和不同光束条件下详细测量电子云的形成。该计划将包括设计工作，以发展电子云测量技术的性能和多样性，以及验证或改进科学界用于数值模拟的电子云模型。这项研究将与费米实验室和阿贡国家实验室的专家合作进行。通过这个项目，印度理工学院正在建立一个加速器物理和材料研究的新生研究生项目，以支持未来的加速器发展，学生参与研究的各个方面，从硬件到建模再到数值模拟。
