This execution of the innovative SC concept promptly earned van der Meer a share of the 1984 Nobel Prize in Physics. A terahertz-bandwidth extension of SC was proposed in 1993 by Mikhailichenko and Zolotorev. This Optical Stochastic Cooling (OSC) used visible or infrared light rather than microwaves and was extended shortly after by Zolotorev and Zholents to the so-called transit-time method of OSC. The world’s first experimental demonstration of OSC has just concluded at Fermilab’s Integrable Optics Test Accelerator (IOTA) ring. In this presentation, we will describe the OSC concept, the IOTA ring and OSC apparatus and then present the first experimental results for cooling and heating in one, two and three dimensions. We will also describe experimental studies of a single electron interacting with itself via the OSC physics. PB - JACoW Publishing CP - Geneva, Switzerland ER -
