%X Rational design and implementation of new generations of functional materials for energy conversion and storage, requires better fundamental understanding of these systems along with the ability to predict their properties accurately. [1, 2, 3] Utilizing thin film systems, the knowledge of the driving parameters to obtain them in high quality is crucial [4]. Molecular Beam Epitaxy (MBE) proves to be a versatile method to grow high quality and high purity epitaxial films with low intrinsic defect concentrations and atomic-layer control.At the JCNS thin film laboratory, we run an oxide MBE system for the growth of various types of samples, i.e. “classical” magnetic thin films, transition metal oxide heterostructures or just thin gold films for soft matter studies, acting as defined surfaces.  However, every sample system comes with its own challenges which makes thin film growth a research topic on its own.In the presentation, we will give an overview for high quality metal and complex oxide thin film systems all fabricated in the JCNS thin film laboratory, like SrCoOx, La1-xSrxMnO3, Fe4N or Cu/Fe multilayers. The focus lies on stoichiometry, morphology and thickness precision and detailed information about the possibilities in sample fabrication for users will be given.For quasi in-situ neutron reflectometry on thin films which are sensitive to ambient air a small versatile transfer chamber can be utilized for sample transfer and measurement from the MBE laboratory to the neutron instrument MARIA [5].  Both, the MBE setup and the transfer chamber may be booked in combination with an application for beam time at neutron instruments like MARIA.[1] R.
