Lay Summary (German)

Lead
Das Labor für Myonenspin-Spektroskopie am Paul Scherrer Institut betreibt die weltweit führende µSR-Nutzeranlage mit sechs fest installierten Instrumenten an fünf separaten sekundären Myon-Strahllinien des HIPA-Protonenzyklotron-Komplexes. Es besteht ein dringender Bedarf an einer neuen flexiblen Probenumgebung für Myonenexperiment, um den unterschiedlichen Bedürfnissen einer breiten schweizerischen und internationalen wissenschaftlichen Nutzergemeinschaft gerecht zu werden.
Lay summary
Ziel unseres Forschungsprojektes ist die Entwicklung eines neuartigen Messinstrumentes zur Untersuchung der kondensierten Materie. Dieses Instrument nutzt den weltweit leistungsfähigsten kontinuierlichen Myonenstrahl an der Schweizer Myonen Quelle (SμS) des Paul Scherrer Instituts. Das neue und flexible Instrument mit dem Namen FLAME (Flexible and Advance MuSR Environment) wird eine große Anzahl von teilweise einzigartigen Merkmalen aufweisen, die von den schweizerischen und internationalen Forschern für ihre Materialforschung genutzt werden. Mit diesem Instrument sollen offene Fragen zu exotischen Zuständen der Materie, wie z.B. dem einer magnetischen Spin-Flüssigkeit oder der Supraleitung geklärt werden.

Unsere Arbeit erforscht einerseits grundlegende Eigenschaften unkonventioneller Supraleiter, neuartiger frustrierter Magnete, Vielteilchen-Phänomene in Festkörper. Des Weiteren sollen Möglichkeit zur Manipulation (Einschalten oder Ausschalten) dieser Eigenschaften gesucht werden um diese z.B. in den technischen Anwendungen der modernen Informationstechnologie und des effizienten Energiemanagements zum Einsatz zu bringen.

Abstract

We propose to build a new muSR instrument with a FLexible and Advanced MuSR Environment (FLAME) at the world’s most powerful continuous muon beam at the Swiss muon Source (SµS) of the Paul Scherrer Institute. FLAME will comprise a large set of partially unique features which were requested by the Swiss and international users of the worldwide leading PSI µSR user facility that is operated by the Laboratory for Muon Spin Spectroscopy (LMU). The SNF R'Equip request will fund some components of the sample environment. PSI on the other hand will cover the costs of the µSR spectrometer, the substantial upgrade of the beam-line, the needed basic infrastructure, the significant technical and engineering manpower to realize the project, and will match the R’Equip investment.FLAME will especially possess vastly more experimental capabilities and a factor of 100 increase in data quality with respect to the outdated instrument LTF that it will replace. To name a few of its characteristics, FLAME will cover a broad temperature range from 20 mK to room temperature with magnetic fields from true zero fields smaller than 5 µT up to 3 T in longitudinal as well as transverse field geometry, it will allow measuring small samples with an area of a few square millimeters with practically no background and allow for in-situ modification of the sample properties at all temperatures by external stimuli e.g. by electric fields or uniaxial pressure.Therefore FLAME will allow a broad range of experiments that have not been possible up to now. Hence, we are confident that FLAME as an advanced, versatile and extendable µSR instrument will present a considerable gain for the Swiss research infrastructure and that it will strengthen the world leading position of the Swiss µSR facility.FLAME with its new capabilities will be used for a broad range of scientific questions which are either interesting from a fundamental or from an applied point of view as exemplified by the already funded research projects mentioned in this application.
