abstract = {A new neutron spin-echo technique based on the use of
time-gradient magnetic fields, TGF NSE, can be used for
purposes of small-angle neutron scattering and
reflectometry. It employs linearly rising magnetic fields
that can be created in simple solenoids or thin magnetic
foils, thus allowing for a construction of long spin turners
that can be tilted to rather small incident angles as
required for high-resolution angular measurements. However,
in contrast with the use of static or radio-frequency
magnetic fields as in the well-known SESANS, the use of
time-gradient magnetic fields results in the unusual
dependence of the spin-echo length on neutron
wavelength-lambda(3) rather than lambda(2). This allows for
a significantly higher Q-resolution and for a very
significant increase of Q-range with the latter feature
especially valuable for the time-of-flight operation mode
with pulsed neutron sources. We will consider the TGF
spin-echo small-angle neutron scattering/reflectometer setup
in detail and compare its parameters with those of the
state-of-the-art SESANS instrument OFFSPEC at ISIS. (C) 2010
