Schmitt, Julien (author), Zeeuw, Jan Joost (author), Zeeuw, Jan Joost (author), Plomp, J. (author), Bouwman, W.G. (author), Washington, Adam L. (author), Duif, C.P. (author), Thijs, M.A. (author), Parnell, S.R. (author)The initial formation stages of surfactant-templated silica thin films which grow at the air-water interface were studied using combined spin-echo modulated small-angle neutron scattering (SEMSANS) and small-angle neutron scattering (SANS). The films are formed from either a cationic surfactant or nonionic surfactant (C16EO8) in a dilute...journal article 2020

Geerits, N. (author), Parnell, S.R. (author), Thijs, M.A. (author), Bouwman, W.G. (author), Plomp, J. (author)A time of flight MIEZE spectrometerstudyis presented. The instrumentuses solenoid radio frequency(RF)spin flipperswithsquare pole shoes and a magnetic yoke. These flippers can achieve higherstaticfields than conventional resonant RF spin flippers, which employ an air core.High fields are crucial for the construction of a high resolution and...journal article 2019

Sales, M. (author), Plomp, J. (author), Bouwman, W.G. (author), Tremsin, Anton S. (author), Habicht, Klaus (author), Strobl, Markus (author)Spin-Echo Modulated Small Angle Neutron Scattering with spatial resolution, i.e. quantitative Spin-Echo Dark Field Imaging, is an emerging technique coupling neutron imaging with spatially resolved quantitative small angle scattering information. However, the currently achieved relatively large modulation periods of the order of millimeters are...journal article 2017

Sales, Morten (author), Plomp, J. (author), Habicht, Klaus (author), Tremsin, Anton (author), Bouwman, W.G. (author), Strobl, Markus (author)Spin-Echo Modulated Small Angle Neutron Scattering (SEMSANS) in Time-of-Flight (ToF) mode has been shown to be a promising technique for measuring (very) small angle neutron scattering (SANS) signals and performing quantitative Dark-Field Imaging (DFI), i.e., SANS with 2D spatial resolution. However, the wavelength dependence of the...journal article 2016

(author)We report on measurements of spatial beam modulation of a polarized neutron beam induced by triangular precession regions in time-of-flight mode and the application of this novel technique spin-echo modulated small-angle neutron scattering (SEMSANS) to small-angle neutron scattering in the very small angle range. It is shown that this method can...journal article 2012

Rekveldt, M.T. (author), Duif, C.P. (author), Kraan, W.H. (author), Plomp, J. (author), Bouwman, W.G. (author)The polarization optimization in a small angle scattering spin-echo setup is considered, under the depolarization and phase errors that occur in field transition regions by improper adjustment of inclined magnetized foils as n-flippers. Various correction procedures are discussed. In these setups with precession fields perpendicular to the beam...journal article 2008
