Abstract
A Cs ion-beam transport experiment is in progress to study beam behavior under extreme space charge conditions. A five-lens section matches the beam into a periodic electrostatic quadrupole FODO channel and its behavior is found to agree with predictions. With the available parameters (⩽200 keV, ⩽20 mA, πεn ⩾ 10-7 π rad-m, up to 41 periods) the transverse (betatron) oscillation frequency (γ) can be depressed down to one-tenth of its zero current value (γo), where γ2 = γ2o - ω2p/2, and ωp is the beam plasma frequency. The current can be controlled by adjustment of the gun and the emittance can be controlled independently by means of a set of charged grids.Keywords
