Abstract Beam dynamics studies are performed in the context of a C-Band hybrid photo-injector project developed by collaboration between UCLA/Sapienza/INFN-LNF/RadiaBeam [1, 2]. These aim to explain beam behaviour through beam-slice evolution, using analytical and numerical approaches. An understanding emittance oscillations is obtained starting from slice analysis, which allows correlation pos...

The space charge distribution in low-density polyethylene (LDPE) was measured with the pulsed electroacoustic (PEA) method. We used three types of LDPE: LDPE-L and LDPE-H were prepared by the high pressure process, and m-LDPE was polymerized with a metallocene catalyst. Space charge in LDPE strongly depended upon the electrode material. Semiconductive electrodes enhanced carrier injection into ...
