000825744 520__ $$aMARIA, belonging to JCNS at MLZ in Garching, is a dedicated versatile instrument for polarised neutron reflectometry (PNR) and grazing incidence small angle neutron scattering (GISANS) studies of ultra-thin films. However, due to limited space a UHV system for thin film growth and in-situ measurements cannot be placed on-site. Hence, up to now ultra thin films which are sensitive to ambient air have been fabricated in the MBE system located in the thin film laboratory nearby and were covered by protecting cap layers in-situ. However these layers may change the physical properties of the sample, which is undesirable and prevents from further manipulation of the sample, e.g. growth of additional layers.Recently, we have solved this problem by developing a handy mini UHV-chamber which is capable for both, sample transfer and quasi in-situ measurements at the neutron reflectivity instrument, respectively. Quasi in-situ polarized neutron reflectivity (PNR) measurements can be performed at room temperature in magnetic fields of up to 600 mT at MARIA.Our solution consists of a DN CF-40 cube with two opposing sapphire windows for the neutron beam, a combined non evaporable getter and ion pump for keeping the vacuum, a wobble stick, which is needed for in-situ sample transfer and also serves as sample holder for samples of up to 1 cm2 and a valve for sample exchange by mounting the chamber on the MBE system. The pressure in the transfer chamber is kept in the 10−10 mbar range during transport and PNR measurement.We present first polarized neutron reflectivity measurements on Co ultra-thin films at room temperature at different magnetic fields in the Q-range up to 0.2 Å−1. Booking of the access to the MBE system as well as the transport chamber is possible via the MLZ user office system in combination with an application for a beam time at neutron instruments like MARIA.This project is part of the nanoscience foundry and fine analysis project (NFFA, www.nffa.eu) and has received funding from the EU’s H2020 research and innovation programme under grant agreement N. 654360.
