Beam Injection Experiments using Space Charge Lenses
Space charge lenses for ion beam focussing are in theory, especially for singly charged heavy ion beams at low velocities, superior to other lens systems [1]. On the other hand previous experiments [2] have shown, in contrary to the theoretical forecast, a small degree of lens filling and serious emittance growth. Newer experiments [3] demonstrated a much better degree of lens filling and subst...
متن کاملSpace-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...
متن کاملOptimum Beam Creation in Photoinjectors Using Space-charge Expansion∗
It has recently been shown that by illuminating a photocathode with an ultra-short laser pulse of appropriate transverse profile, a uniform density, ellipsoidally shaped bunch is dynamically formed, which then has linear space-charge fields in all dimensions inside of the bunch. We study here this process, and its marriage to the standard emittance compensation scenario that is implemented in m...
متن کاملEffect of Space Charge on Stability of Beam Distribution in the Sns Ring
In the Spallation Neutron Source (SNS) ring, multi-turn injection is employed to obtain a large transverse beam size which significantly reduces the space-charge tune shift of the accumulated beam. Careful choice of the painting scheme and bump function is required to obtain the desired beam profile together with low beam loss. In this paper we examine, both analytically and numerically, the ef...
