Phoenix: Our principal UHV-IRRAS instrument

UHV-IRRAS instrument - Front View

 

Phoenix is our principal UHV-IRRAS instrument for the study of electron-induced processes at surfaces.  Current projects include the dissociation of Ni(CO)4 and the study of secondary reactions in thin organic films.  It can work with samples prepared in the laboratory ambient (transferred via the load-lock) or by in-situ deposition (prepared via the gas-phase dosing system).  Cryogenic sample supports allow the deposition of most molecular species, as well as Ar, Kr and Xe.
