The Slac Low Emittance Accelerator Test Facility

SLAC is proposing to build a new Accelerator Test Facility (ATF) capable of producing a 50 MeV electron beam with an extremely low geometric tran8ver8e emittance (1.5 x lo-lo rad.m) for the purpose of teeting new methods of acceleration. The low emittance will be achieved by a88ernbling a liiur accelerator using one standard SLAC three-meter r&ion and a 400 kV electron gun with a very rmall pho...

Continuous Electron Beam Accelerator Facility,

We use local quark-hadron duality to estimate the purely nonperturbative soft contribution to the γ * p → ∆ form factors. Our results are in agreement with existing experimental data. We predict that the ratio G * E (Q 2)/G * M (Q 2) is small for all accessible Q 2 , in contrast to the pQCD expectations that G * E (Q 2) → −G * M (Q 2).

Low-Level RF System Design for the Accelerator Test Facility (ATF) Damping Ring

The ATF damping ring [1] was built to demonstrate the production of low emittance, high current beams for future linear colliders. To attain high beam currents, multiple high current bunch trains are required. The low-level rf system should be designed to minimize both steady-state and transient beam loading effects in the accelerating cavities. In addition the design should be sufficiently fle...

Space-charge effects in high brightness electron beam emittance measurements

The measurement of emittance in space-charge dominated, high brightness beam systems is investigated from conceptual, computational, and experimental viewpoints. As the self-field-induced collective motion in the low energy, high brightness beams emitted from photoinjector rf guns are more important in determining the macroscopic beam evolution than thermal spreads in transverse velocity; tradi...

Slice Emittance Measurements at the SLAC Gun Test Facility*

A goal of the Gun Test Facility (GTF) at SLAC is to investigate the production of highbrightness electron beams for the Linac Coherent Light Source (LCLS) X-ray FEL. High brightness in the rf photocathode gun occurs when the time-sliced emittance is nearly the same as the cathode thermal emittance and when the slices are all lined up, i.e., their Twiss parameters are nearly identical. In collab...
