The complementary surface techniques of ultra-high vacuum (UHV) ESR and CREMSEE (cyclotron resonance from microwave-induced secondary electron emission) are described_ it is shown in a study of a stable pammagnetic molecule on Cu and Ag surfaces, that it appears to lose its pammagnetism while forming a chemisorbed complex with tbe metal surface. Control experiments on air-oxidned Cu are also pr...

Abstract Processes of the secondary electron emission (SEE) from walls are included into Numerical Advanced Model Electron Cyclotron Resonance Ion Sources (NAM-ECRIS). It is found that SEE strongly influences confinement time and ion production. With modified model, we observe reactions source to changes in a gas flow an injected microwave power. The performance with scaling hexapole magnetic f...

The electron cyclotron resonance (ECR) ion sources are increasingly popular for producing highly charged ions. With worldwide proposals to build the Isotope Seperator OnLine (ISOL) facility being at hand, it becomes important to design a high efficiency ion source as a charge breeder for the secondary beam. A novel type of ECR ion source based on a flat magnetic field configuration has been pro...

1098-4402= The problems of spin-polarized free-electron beam interaction with electromagnetic wave at electronspin resonance conditions in a magnetic field and of superradiant spin-flip radiative emission are analyzed in the framework of a comprehensive classical model. The spontaneous emission of spin-flip radiation from electron beams is very weak. We show that the detectivity of electron spi...

A microwave discharge ion source (MDIS) operating at the Laboratori Nazionali del Sud of INFN, Catania has been used to compare the traditional electron cyclotron resonance (ECR) heating with an innovative mechanisms of plasma ignition based on the electrostatic Bernstein waves (EBW). EBW are obtained via the inner plasma electromagnetic-to-electrostatic wave conversion and they are absorbed by...
