LANRS has started
Aim of the project
The aim of the LANRS project is to establish nuclear inelastic scattering as a unique experimental method for determination of the lattice dynamics of individual nano-objects using nano-focused x-ray beam at PETRA III/IV. In particular, it will allow one to perform a systematic study of the phonon density of states of individual nano-objects as a function of size, shape, strain, and defects concentration. This currently missing fundamental knowledge will enable a full control and a precise manipulation of the lattice dynamics by nanostructuring, which could potentially revolutionize important fields such as thermoelectric energy conversion and thermal management of micro- and nanoelectronics.
To enable these experiments, a novel detector array based on the Trench Isolated Low Gain Avalanche Diodes (TI-LGAD) technology, recently demonstrated for soft x-rays, will be designed and manufactured in the frame of the LANRS project.
A layout of the envisaged experimental setup for in situ experiments on individual nano-objects at P01 of PETRA III/IV. The ultrahigh vacuum (UHV) system was designed and manufactured within the BMBF-funded project NUKFER. The TI-LGAD detectors array will be manufactured with the LANRS project.
