Phase Space Tomography: A Simple, Portable and Accurate Technique to Map Phase Spaces of Beams with Space Charge
In order to understand the charged particle dynamics, e.g. the halo formation, emittance growth, x-y energy transfer and coupling, knowledge of the actual phase space is needed. Other the past decade ...

Manipulation of the Longitudinal Profile
We present studies of transverse emittances and electron beam pulse length for various operating points of the electron source: electron beam charge, laser length and spot size, and solenoid settings....

TheUniversity of Maryland Electron Ring (UMER) is a scaled modelto investigate the physics of such intense beams. It usesa 10-keV electron beam along with other scaled beam parametersthat model the larger machines but at a lower cost.Recently, multi turn operation of the ring (3.6 m diameter)has been achieved. In order to have full current transportof the electron beam, and to increase the number ofturns of the beam around the ring, injection of thebeam from the straight section into the ring becomes crucial.In this work, we report experimental results from the injectionand matching of a space charge dominated beam and anemittance dominated beam. We also describe and analyze two methodsof injection of the electron beam from the straight sectioninto the ring. In one of the methods, the twoinjection quads are fixed to a preset value, while inthe other both the injection quads are switched off (Collinsinjection). ©2006 American Institute of Physics
