Temperature dependence in fast-atom diffraction at surfaces
Peng Pan, Maxime Debiossac, Philippe Roncin
Grazing incidence fast atom diffraction at crystal surfaces (GIFAD or FAD) has demonstrated coherent diffraction both at effective energies close to one eV ( 14 pm…
A setup for grazing incidence fast atom diffraction
Peng Pan, Jaafar Najafi Rad, Philippe Roncin
We describe a UHV setup for grazing incidence fast atom diffraction (GIFAD) experiments. The overall geometry is simply a source of keV atoms facing an imaging detector. Therefore,…
Revisiting Atomic Collisions Physics with highly charged ions, A tribute to Michel Barat
Philippe Roncin
Michel Barat passed away in November 2018 at the age of 80 after a rich career in atomic and molecular collisions. He had participated actively in formalizing to the electron promo…
Refraction of fast Ne atoms in the attractive well of LiF(001) surface
Maxime Debiossac, Philippe Roncin, A. G. Borisov
Ne atoms with energies up to 3 keV are diffracted under grazing angles of incidence from a LiF(001) surface. For a small momentum component of the incident beam perpendicular to th…
Alternative solutions to caesium in negative-ion sources: a study of negative-ion surface production on diamond in H 2 /D 2 plasmas
Gilles Cartry, Dmitry Kogut, Kostiantyn Achkasov +9
This paper deals with a study of H-/D-negative ion surface production on diamond in low pressure H2/D2 plasmas. A sample placed in the plasma is negatively biased with respect to p…
Quantum regime for the nuclear energy loss of fast atoms above crystal surfaces
Philippe Roncin, Maxime Debiossac
To describe the grazing scattering of keV atoms at surface, a new quantum binary collision model have been proposed where the dynamical properties of the surface atoms are consider…
Energy loss and inelastic diffraction of fast atoms at grazing incidence
Philippe Roncin, Maxime Debiossac, Hanene Oueslati +1
The diffraction of fast atoms at grazing incidence on crystal surfaces (GIFAD) was first interpreted only in terms of elastic diffraction from a perfectly periodic rigid surface wi…
A large area high resolution imaging detector for fast atom diffraction
Sylvain Lupone, Pierre Soulisse, Philippe Roncin
We describe a high resolution imaging detector based on a single 80 mm micro-channel-plate (MCP) and a phosphor screen mounted on a UHV flange of only 100 mm inner diameter. It rel…
Elastic and inelastic diffraction of fast atoms,\linebreak Debye-Waller factor and Mössbauer-Lamb-Dicke regime
Philippe Roncin, Maxime Debiossac
The diffraction of fast atoms at crystal surfaces is ideal for a detailed investigation of the surface electronic density. However, instead of sharp diffraction spots, most experim…
Helium diffraction on SiC grown graphene, qualitative and quantitative description with the hard corrugated wall model
Maxime Debiossac, Asier Zugarramurdi, Zhao Mu +3
The Moiré structure of epitaxial graphene mono layer grown on 6H-SiC(0001) has been investigated recently by grazing incidence fast atom diffraction, and the results were compared…
Fast atom diffraction inside a molecular beam epitaxy chamber, a rich combination
M. Debiossac, P. Atkinson, A. Zugarramurdi +7
Two aspects of the contribution of grazing incidence fast atom diffraction (GIFAD) to molecular beam epitaxy (MBE) are reviewed here: the ability of GIFAD to provide \emph{in-situ}…
Atom beam triangulation of organic layers at 100 meV normal energy: self-assembled perylene on Ag(110) at room temperature
Nataliya Kalashnyk, Philippe Roncin
The controlled growth of organic layer on surface is still awaiting for an on-line reliable monitoring that would allow improvement of its quality. We show here that the self-assem…
Image processing for grazing incidence fast atom diffraction
Maxime Debiossac, Philippe Roncin
Grazing incidence fast atom diffraction (GIFAD, or FAD) has developed as a surface sensitive technique. GIFAD is less sensitive to thermal decoherence but more demanding in terms o…
A large open ratio, time and position sensitive detector for time of flight measurements in UHV
S. Lupone, S. Damoy, A. Husseen +4
We report on the construction of a UHV compatible 40 mm active diameter detector based on micro channel plates and assembled directly on the feed-throughs of a DN63CF flange. It is…

C. A. Ríos Rubiano, G. A. Bocan, M. S. Gravielle +3
Experimental diffraction patterns produced by grazing scattering of fast helium atoms from a Ag(110) surface are used as a sensitive tool to test both the scattering and the potent…
Diffraction of fast atoms and molecules from surfaces
J. R. Manson, Hocine Khemliche, Philippe Roncin
Prompted by recent experimental developments, a theory of surface scattering of fast atoms at grazing incidence is developed. The theory gives rise to a quantum mechanical limit fo…
