Matter‐wave microscopy can be dated back to 1932 when Max Knoll and Ernst Ruska published the first image obtained with a beam of focussed electrons. In this paper a new step in the development of matter‐wave microscopy is presented. We have created an instrument where a focussed beam of neutral, ground‐state atoms (helium) is used to image a sample. We present the first 2D images obtained using this new technique. The imaged sample is a free‐standing hexagonal copper grating (with a period of… Expand
Focusing of a neutral helium beam below one micron
In 2008 we presented the first images obtained with a new type of matter wave microscope: NEutral Helium Atom MIcroscopy (NEMI). The main features in NEMI are the low energy of the atoms (<0.1 eV)Expand
Neutral atom and molecule focusing using a Fresnel zone plate
Focusing of neutral atoms and molecules has several potential applications. The very first microscopy images using helium as an imaging probe were published earlier this year. Another possibleExpand
Free-standing silicon-nitride zoneplates for neutral-helium microscopy
The ground-state helium-4 beam employed by the microscopy technique discussed in this article interacts exclusively with the atoms in the topmost sample-monolayer. Its low-energy (tens of meV) andExpand
Atom sieve for nanometer resolution neutral helium microscopy
Neutral helium microscopy is a new tool for imaging fragile and/or insulating structures as well as structures with large aspect ratios. In one configuration of the microscope, neutral helium atomsExpand
Optimization of a constrained linear monochromator design for neutral atom beams.
TLDR
The main result of this work is optimal design parameters based on models for this linear monochromator set-up followed by a second zone plate for focusing, performed for minimizing the focal spot size and maximizing the centre line intensity at the detector position for an atom beam simultaneously.

Abstract The nascent field of neutral helium microscopy, as well as many applications within atomic and molecular beam research, are currently restricted by low detector sensitivity. To compensate,Expand
Multiple scattering in scanning helium microscopy
Using atom beams to image the surface of samples in real space is an emerging technique that delivers unique contrast from delicate samples. Here, we explore the contrast that arises from multipleExpand
