Similarly, the diffusion in ionic liquids and solvent-based electrolytes has been attracting great interest (Lundin et al., 2021 ▸ Burankova et al., 2018 ▸ Adya et al., 2007 ▸ Osti et al., 2019 ▸). Since many batteries rely on ion exchange and/or the ionic conductivity of lithium and hydrogen, determination of diffusion mechanisms in these materials is essential in understanding and improving this performance (Hester et al., 2016 ▸ Kuznetsov et al., 2021 ▸ Li et al., 2021 ▸ Klein et al., 2021 ▸ Okuchi et al., 2018 ▸). ![]() Another major field of research where such instrumentation is required concerns hydrogen- or lithium-based functionalities in solids. For instance, such high-resolution spectroscopy over a large dynamic range promises unambiguous identification of quantum-spin liquids (Paddison et al., 2017 ▸ Shen et al., 2016 ▸), where knowledge of spectral details such as the existence of tiny gaps and the structure of the low-lying modes is key. In magnetic materials this includes spin-frozen states in classical spin glasses and highly correlated spin states in geometrically frustrated systems (Musgraves et al., 2019 ▸). Key scientific questions that require high energy resolution over a large Q range involve, for example, the investigation of ground states without long-range order or well defined excitations. The need for high-resolution neutron spectroscopy over a wide range of momentum transfers, Q, has motivated major advances in neutron instrumentation in recent years. To illustrate the feasibility of TIGER, this paper presents the details of its implementation at the RESEDA beamline at FRM II by means of an additional velocity selector, polarizer and analyzer. In turn, the thermal MIEZE option for greater ranges (TIGER) closes the gap between classical neutron spin-echo spectroscopy and conventional high-resolution neutron spectroscopy techniques such as triple-axis, time-of-flight and back-scattering. The use of thermal neutrons increases the range of validity of the spin-echo approximation towards shorter spin-echo times. The second advantage is that multi-analyzer setups can be implemented with comparatively little effort. This allows for the study of spin fluctuations in ferromagnets, and facilitates the study of samples with strong spin-incoherent scattering. ![]() The first is the possibility to investigate spin-depolarizing samples or samples in strong magnetic fields without loss of signal amplitude and intensity. MIEZE has two prominent advantages compared with classical neutron spin echo. Saturday broadcasts of Echoes are the programs listed as Tuesday.A modulation of intensity with zero effort (MIEZE) setup is proposed for high-resolution neutron spectroscopy at momentum transfers up to 3 Å −1, energy transfers up to 20 meV and an energy resolution in the microelectronvolt range using both thermal and cold neutrons. **NOTE: Friday broadcasts of Echoes are the programs listed as the previous Monday. Listeners to Echoescan find current program playlists by visiting. Drawing upon singer-songwriters, dream-pop and electronica, the voices Moby, Beck, Bon Iver, Lana Del Rey, Coldplay and Tori Amos are now an integral part of the Echoes soundscape. ![]() But while those sounds are still an integral part of the program, Echoes now blends contemporary vocals into the mix with roughly a 50/50 split between the two styles. It’s one of the keenly unique sounds in public radio. Since its genesis in 1989, Echoeshas been creating chilled environments drawn from electronic, ambient, space music, world fusion and contemporary classical music. ![]() Echoes is a sound that is cross-cultural and trans-millennial, merging cultures and forms, technology and tradition, the ancient past and the possible future. Echoes brings together a wide array of styles, from acoustic to electronic, jazz to space music, the avant-garde to rock. Echoes is a daily two-hour music soundscape “Music for the Chillout of the Night,” distributed by Public Radio International with host John Diliberto.
