lattice of spins is called a magnon, while a similar excitation of the atom lattice is known as a phonon. Phonons and magnons can be conveniently observed with the help of a neutron three-axis spectrometer ... Yannick Raoul. ©2013-2018 Institut Laue-Langevin. Magnons is a 3D animation demonstrating the interaction of a neutron with the atomic spins ...

arrangement of polymer micelles with a diameter of about 180 Å close to a hydrophilic and a hydrophobic coated silicon wafer. For the top panels the sample is in a liquid phase. The ring of increased intensity ... sample in a crystalline cubic phase. Close to the hydrophilic interface a cubic close packed structure is formed whereas close to the ...

Calibration A very simple detector efficiency calibration consists simply in measuring a vanadium or a plexiglass sample to obtain a nearly flat background. A Two-Theta scan has to be performed to obtain a the ... not monitor-controlled. You may perform a simple acquisition, a scan or a coupled scan (moving one or two motors between the steps of a ...

the ILL. ICL allocated two average programmers, of a quality which might be expected to aid a transition over a period of up to a year. CII introduced a young American, to work on the CICG system. We never ... systems there was a similar hierarchical file structure, and and command given was interpreted as a valid pl1 instruction to seek out and ...

will be 3D, each layer containing data of a specific flipper state. If a flipper that is 'off' is labelled with a 0 and a flipper that is 'on' is labelled with a 1, the arrays will be stacked in binary fashion ... create a workspace from a series of datasets with different flipper states NECESSARY VARIABLES nums=EITHER a string with the filenumbers ...

In other words, a program compiled for, say, a large matrix inversion would use the same huge memory space if a small or large matrix is to be inverted. Since the frequency at which a batch program was ... space, Yvon Siret developed a clever variable memory allocation routine for the DEC10 and said to A.Filhol " These are the 10 program lines I'm ...
