abstract = {The investigation of ultrathin films which are sensitive to
ambient air at large scale instruments is a challenge as the
capabilities for on-site growth UHV chambers to measure
in-situ are often limited, mostly due to lacking space. A
common solution is the use of protecting cap layers on top
of the films. However they might change the physical
properties of the sample.Our solution is a handy mini
UHV-chamber which is used for sample transfer and quasi
in-situ measurements at the neutron reflectivity instrument
MARIA of the Jülich Centre for Neutron Science at MLZ in
Garching. The samples are prepared in the adjacent thin film
laboratory by molecular beam epitaxy and moved into the
compact chamber for transfer. It is equipped with sapphire
windows, an SAES getter pump and a wobble stick, which
serves also as a sample holder for samples of up to
1.4~cm$^2$. The pressure in the transfer chamber is kept
below $10^{-9}$ mbar. Neutron reflectivity measurements can
be performed at room temperature in magnetic fields of up to
600~mT. We present first polarized neutron reflectivity
measurements on Co thin films at room temperature in a
magnetic field of 300 mT in the Q-range up to 0.2
\AA$^{-1}$.},
