Redox state determination of eclogite xenoliths from Udachnaya kimberlite pipe (Siberian craton), with some implications for the graphite/diamond formation
The formation of diamonds within eclogitic rocks has been widely linked to the fate of carbon during subduction and, therefore, referred to conditions of pressure, temperature, and oxygen fugacity (fo2). Mantle-d...

The oxygen fugacity at which graphite or diamond forms from carbonate-bearing melts in eclogitic rocks
The oxygen fugacity (fO2) at which carbonate-bearing melts are reduced to either graphite or diamond in synthetic eclogite compositions has been measured in multi-anvil experiments performed at pressures between ...

An EBIS for charge state breeding in the SPES project
The ‘charge state breeder’, BRIC (breeding ion charge) is in construction at the INFN section of Bari (Italy). It is based on EBIS scheme and it is designed to accept radioactive ion beam (RIB) with charge sta...

First demonstration of “white-light” laser cooling of a stored ion beam
“White-light” cooling of an ion beam confined in a storage ring has been demonstrated at Test Storage Ring in Heidelberg. Measurements aimed at comparing “white-light” with single-mode laser cooling show that ...

A Monte Carlo simulation of a stroboscopic laser diagnostics of ordered ion beams in a storage ring
A Monte Carlo code combined with a particle tracking program has been used to study a stroboscopic laser diagnostic system that is able to detect a string-like ordered ion beam. Different ion species have been...

A Radiofrequency Trap for Tests on Production and Excitation of Ions
Most of the reaction vessels which are used as ion sources, ion lasers and to study reactions of ionized species use a confinement of the ionizing electrons with magnetic fields, while no attempt is made to co...

Design of a continuous-wave free-electron laser experiment using an electrostatic accelerator with very high recovery efficiency of the electron beam
In this paper the free-electron laser (FEL) experiment SEAFEL in progress at the Legnaro (Padova) INFN laboratory is presented. The accelerator characteristics and FEL parameters are discussed. The laser could...

Inhomogeneous broadening effects in Optical Klystrons operating with accelerating devices without radiative dam**
In this letter paper we analyse the effect of electron-beam qualities (namely, energy spread and emittances) on both spontaneous emission and gain of an Optical Klystron (OK).

Angular-spread effect in a free-electron laser with a nonmonoenergetic beam
We perform analytically the calculation of the small signal gain for a free-electron laser with an electron beam having both energy and angular spread. We obtain that the gain is substantially reduced by the p...

The converter and the transverse optical klystron
In this paper we present a survey of the classical theory of the coherent emission of radiation in the optical and submillimetre range from a relativistic electron beam in a transverse, plane-polarized, spatia...

Coherent radiation from electrons in transverse periodic fields
The coherent radiation from a relativistic electron beam in transverse, plane-polarized, spatially periodic magnetic fields is calculated by taking into account anharmonic effects. Coherent radiation is interp...

Free-electron lasers and masers on curved paths
The possibility of building free-electron lasers and masers with quasi-circular undulators is considered. The two-mirror cavity is replaced by a suitable waveguide. The magnetic field along the orbit has a con...
