interferometry" says Michael Jentschel from the ILL. "Because if you can control two crystals well enough that interferometry is possible, you can also increase the distance and expand the size of the overall ... succeeded for the first time in building a neutron interferometer from two separate crystals. Particles can move as waves along different ...

multiplexed spectrometer consisting of a multi-analyser and a position-sensitive detector (PSD). It can also be used in a more classical configuration: mono-analyser and mono-detector. The multiplexed s

of such a novel class of multiferroic materials. The structure of these transition metal oxyhalides can be seen in Figure a. With a critical temperature of approximately 70 K these multiferroics have to

amplification region, providing high local counting rate capability. More detailed information about MSGCs can be found in [1] a nd [2] . This technique was invented by Anton Oed at the ILL in 1988 for D20, and

others outward. This ‘2 in 2 out’ local constraint can be achieved in a number of ways that grow exponentially with the number of tetrahedra so that no order can occur. A spin ice should therefore be viewed ... has found that the fragmented state can, in fact, be induced with the help of a second interpenetrating magnetic lattice, and the main ...

equiped with the old PSD covering only 128º in 2θ. A cryostat 1.5-300K or even a dilution cryostat can be mounted on the D1B diffractometer enabling to investigate magnetic structures on powder samples

pulses of fast neutrons catch up with pulses of slower neutrons after the chopper. The chopper speed can be adjusted in such a way that all three pulses of different energy arrive at the same time in the ... velocity of the neutrons. Therefore, if neutrons are scattered by a sample, the time-focussing condition can not be accomplished in general. ...

multi-layered coatings can be used for biosensing and biocatalysis. Biomolecular sensors, used to detect toxic substances or specific DNA sequences down to extremely low concentrations, can be made by embedding ... (jpg - 1.11 Mi) Neutron experiments prove that multi-layered functional coatings can be prepared with a simple, single step procedure. ...
