International Collaboration on CESR-TA Program

Abstract

An international collaboration on the CESR-TA (Cornell Electron Storage Ring—Test Accelerator) program, which is a program to investigate electron cloud instability (ECI) issues in the positron damping ring of the ILC (International Linear Collider), is currently underway at Cornell University. KEK is supporting the program through the development of an X-ray beam profile monitor system to measure the extremely small beam size, and through the development of clearing electrodes to mitigate the ECI.
