A 2.1GeV ring design for SRC
(20041014)A design for a twelvesided 2.1GeV electron storage ring is obtained. The design utilizes the combinedfunction magnet approach of the MaxIV design for 1.5GeV and 3GeV rings. The 2.1GeV ring has an emittance of 1.5 ...

Instabilities driven by higherorder modes in an RF system with a passive higher harmonic cavity
(20041014)A passive higherharmonic cavity may be used to suppress parasitic longitudinal coupledbunch instabilities. Our analytic modeling already predicts whether a parasitic higherorder mode (HOM) will cause longitudinal ... 
Instability modeling for passive harmoniccavity operation at MAXlab
(20040326)Instability modeling is performed for passive harmoniccavity operation at MAXlab. For the MAXII 1.5 GeV ring, we consider the 100MHz/500MHz RF system now being constructed with three fundamental cavities and one harmonic ... 
Longitudinal broadband impedance of the Aladdin vacuum chamber and new dipole chamber design
(20040630)An estimate of the longitudinal broadband impedance is obtained by summing estimated impedance contributions from the radiofrequency (RF) cavities, bellows, beam position monitors, Q electrode, vacuum chamber transitions, ... 
Longitudinal wake of a suddenly accelerated electron bunch
(20070223)We consider the longitudinal wake of an electron bunch that is suddenly accelerated. This wake approximates the edgeradiation wake of an electron exiting a bending magnet, the wake of an ... 
Modeling of a passive fourth harmonic cavity for the Hefei Light Source upgrade HLSII
(20100201)The use of a fourthharmonic cavity is studied for the planned upgrade of the 800MeV Hefei Light Source HLSII. Analytic modeling and simulations indicate that such a cavity can successfully suppress parasitic coupled bunch ... 
Multipole specifications for insertion devices in LF15
(20050426)Imperfections in the magnetic field of an insertion device affect the electron storage ring, thereby impacting the users of all beamlines. To minimize adverse effects, the manufacturer is required to meet ... 
Offenergy injection of Aladdin
(20070719)Injection of the Aladdin 800MeV electron storage ring is performed at a low ring energy of 108 MeV, where the stacking time period of 0.8 s is much smaller than the radiation damping time. Electrons are ... 
Partial design of a 980MeV Energy Recovery Linac (ERL)
(20061206)We describe the partial design of a 980MeV energy recovery linac (ERL) with radiofrequency (RF) of 1.5 GHz. We model the linac, recirculation arcs, beam spreader/combiner, and beam compression. The electron gun, gunline, ... 
Twostage bunch compression with resistive impedance approximation of coherent synchrotron radiation
(20070608)Twostage bunch compression, where each stage compresses a chirped beam in a magnetic chicane, may be utilized in the design of a driver for a freeelectron laser (FEL). For the high currents required of an ...
