Single Electrons Emission Diagnostics (SEED)

There is a growing “macroscopic” interest towards fundamentally quantum “microscopic” processes, such as in the emerging areas of quantum communications, quantum computing or non- invasive quantum measurements. A single electron orbiting around the ring and emitting single quanta at the rate of about one event per hundred turns could produce a wealth of information about quantum processes. Hence, there is an interest in revisiting experimentally the problem of a single electron stored in a storage ring “trap” and use state of the art diagnostic equipment to characterize radiation properties in such system. To respond to this challenge, RadiaBeam proposes to utilize Integrable Optics Test Area (IOTA) storage ring presently under construction at Fermilab, which is both available, and ideal in size and properties for single electron studies. We plan to produce a 1.5-meter insertion device to install at the IOTA ring, designed to produce undulator radiation in a visible range, and develop a downstream single photon sensitive diagnostic system which would enable high precision temporal, spectral, spatial and angular characterization of the single electron radiation properties. In Phase I we plan to develop a detailed scientific program for the single electron studies at the IOTA ring, and also optimize and engineer the insertion wiggler. SEED diagnostic system components will be specified, and the layout modeled, in preparation for the Phase II experimental program.Commercial Applications and Other Benefits: Besides the strong scientific case, and educational value, the proposed SEED program overlaps with three important technological thrusts, with a significant commercialization potential: exploration of new methodologies in manipulating quantum systems (i.e. for quantum cryptography); a development and optimization of ultra-sensitive diagnostic instrumentation and low intensity “standard candle” calibration sources; and, improvements to accelerators themselves.
