atto3DR
3-dimensional rotor for in-situ operation
The atto3DR double rotation module provides access to the full magnet-
ic field (e.g. 9 T) in all directions relative to the sample surface. Thus,
instead of rotating the magnetic field, the sample can be arbitrarily
oriented with respect to a fixed external magnetic field vector. Featur-
ing an eucentric rotation (i.e. the two axes of rotation intersect in the
center of sample, which is fixed in space), this makes available a much
larger phase space as compared to conventional vector magnets, where
the field vector is rotated instead. The reason is that split coil configura-
tions generally do not achieve such high field values, despite being sig-
nificantly more expensive. The module comes fully wired and equipped
with a convenient leadless ceramic chip carrier (LCCC) socket with 20
contacts, making sample exchange a quick and easy task.
All parts are non-magnetic, and are compatible with all attoCRYO setups
with a 2” sample space and exchange gas cooling – whether it is a dry
or a liquid setup. The atto3DR allows for rotation around a horizontally
fixed axis, and an additional in-plane axis. This enables a ±90° tilt
between sample surface and field, as well as another ±90° of in-plane
rotation. Thus, any relative orientation between sample and field is
accessible.
