“…The Duke electron storage ring is a two-and-one-half generation light source storage ring with a low emittance and a large energy aperture, dedicated to driving advanced light sources including free-electron lasers and Compton light sources [43][44][45]. The storage ring was first commissioned in 1994 with a maximum operation energy of 1.0 GeV.…”

“…Most of the technical parameters of the storage ring and the OK-4 FEL has been presented in our previous publications [10,8]. The recent developments of the OK-4/Duke storage ring FEL involved installation and commissioning closed orbit measuring system comprised of 34 units of Bergoz BPM electronics [11], the new timing system, the gain modulator [7].…”

In this paper we present the result of the deep-UV lasing with the OK-4/Duke storage ring FEL. The OK-4 FEL was initially commissioned in the near-UV at Duke Free Electron Laboratory in November, 1996 followed by a year-long shutdown. After re-establishing the storage ring operation in early 1998, the OK-4 FEL lasing was demonstrated in the wavelength range of 217 to 256 nm in 1998. A number of lasing modes with electron energies ranging from 300 to 750 MeV have been established to accommodate application research. Starting September, 1998, the coherent deep-UV radiation is used for applications in cornea surgery, cell biology, surface physics, and nuclear physics. In this paper we report the results of the deep-UV lasing with the OK-4/Duke storage ring FEL as well as our plans to advance towards the VUV.

“…The longitudinal profile of the beam undergoes a smooth transition during the creation of the hollow beam and periodic bursts thereafter; no longitudinal breakup of the beam has been observed. It is also worth mentioning that during the commissioning of the Duke storage ring in 1995 interesting beam images with more than one ring were observed with a multibunch beam [17] while adjusting the higher-order harmonic tuners of the rf system. At the time, we believed that these unusual beam distributions were the result of the transverse coupled bunch instability.…”

Anomalous Hollow Electron Beams in a Storage Ring

This Letter reports the first observations of an anomalous hollow electron beam in the Duke storage ring. Created by exciting the single-bunch beam in a lattice with a negative chromaticity, the hollow beam consists of a solid core inside and a large ring outside. We report the detailed measurements of the hollow beam phenomenon, including its distinct image pattern, spectrum signature, and its evolution with time. By capturing the postinstability bursting beam, the hollow beam is a unique model system for studying the transverse instabilities, in particular, the interplay of the wakefield and the lattice nonlinearity. In addition, the hollow beam can be used as a powerful tool to study the linear and nonlinear particle dynamics in the storage ring.
