Design and Test of the Clearing El ectrodes for e- cloud Mitigation in the e+ DANE Ring
Metallic clearing electrodes have been designed to absorb the photo-electrons in the DAΦNE positron ring. They have been inserted in the wiggler and dipole vacuum chambers and have been connected to external high voltage generators. In the paper we present the design of the devices and the results o...

| Sumario: | Metallic clearing electrodes have been designed to absorb the photo-electrons in the DAΦNE positron ring. They have been inserted in the wiggler and dipole vacuum chambers and have been connected to external high voltage generators. In the paper we present the design of the devices and the results of the electromagnetic simulations of longitudinal beam coupling impedances. We also present the results of the RF tests on the installed electrodes. |
