Partial design of a 980-MeV Energy Recovery Linac (ERL)
We describe the partial design of a 980-MeV 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, ...
Instabilities driven by higher-order modes in an RF system with a passive higher harmonic cavity
A passive higher-harmonic cavity may be used to suppress parasitic longitudinal coupled-bunch instabilities. Our analytic modeling already predicts whether a parasitic higher-order mode (HOM) will cause longitudinal ...
Longitudinal broadband impedance of the Aladdin vacuum chamber and new dipole chamber design
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, ...
Instability modeling for passive harmonic-cavity operation at MAXlab
Instability modeling is performed for passive harmonic-cavity operation at MAXlab. For the MAX-II 1.5 GeV ring, we consider the 100-MHz/500-MHz RF system now being constructed with three fundamental cavities and one harmonic ...
Off-energy injection of Aladdin
Injection of the Aladdin 800-MeV 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 ...
Multipole specifications for insertion devices in LF15
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 ...

Terminations, Reductions, and Savings
Copy of Terminations, Reductions, and Savings from the Fiscal Year 2012 United States Budget. The item terminating the Synchrotron Radiation Center is on page 74.
Two-stage bunch compression with resistive impedance approximation of coherent synchrotron radiation
Two-stage bunch compression, where each stage compresses a chirped beam in a magnetic chicane, may be utilized in the design of a driver for a free-electron laser (FEL). For the high currents required of an ...
