Three-dimensional model of a split-crystal x-ray and neutron interferometer
Carlo Paolo Sasso, Giovanni Mana, Enrico Massa
The observation of neutron interference by using a crystal interferometer having a separate analyser opens the way to the construction and operation of interferometers with vast ar…
Neutron interference from a split-crystal interferometer
Hartmut Lemmel, Michael Jentschel, Hartmut Abele +5
We report the first successful operation of a neutron interferometer having a separate beam recombining crystal. We achieved this result at the neutron interferometry setup S18 at…
Progress on the Astrometric Gravitation Probe design
Mario Gai, Alberto Vecchiato, Alberto Riva +13
The Astrometric Gravitation Probe mission is a modern version of the 1919 Dyson-Eddington-Davidson experiment, based on a space-borne telescope with a permanent built-in eclipse, p…
The ASTRA project: a doorway to future astrometry
Mario Gai, Zhaoxiang Qi, Mario G. Lattanzi +15
Astrometric Science and Technology Roadmap for Astrophysics (ASTRA) is a bilateral cooperation between China and Italy with the goal of consolidating astrometric measurement concep…
Interlaboratory consensus building challenge
Giovanni Mana
The manuscript is about an interlaboratory comparison which involved eleven metrology institutes. It comprises four tasks: i) deriving a consensus value from these results; ii) eva…
X-ray phase contrast topography to measure the surface stress and bulk strain in a silicon crystal
Enrico Massa, Carlo Paolo Sasso, Matteo Fretto +2
The measurement of the Si lattice parameter by x-ray interferometry assumes the use of strain-free crystals, which might not be true because of intrinsic stresses due to surface re…
