X-ray diffraction during ultrafast growth of high temperature superconductors: A new challenging project at Alba synchrotron light source
The project consists of designing, building, commissioning and exploiting a new experimental set up devoted to fast thin film growth while acquiring simultaneously diffraction data. It will operate at the NCD-SWEET beamline of ALBA light source (Cerdanyola del Valles , Barcelona). The installation should enable to evaluate ultrafast (~100 ms/frame) crystallization processes during heating ramps of few degrees per second under controlled and reduced atmospheres with a fast 2D XRD detector in a 3 axis goniometer equipped with an XZ stage. The system will be also equipped with a residual gas analysis mass spectrometer and an in-situ conductivity measurement. The samples to be analysed are high temperature superconducting films deposited by chemical solution deposition and grown through the high throughput Transient Liquid Assisted Growth (TLAG) process  for the energy transition, though the installation should be open to other materials interests. The project will also explore the in-situ growth combinatorial experiments with compositional gradients deposited by ink-jet printing , for their evaluation using machine learning algorithms.
The project is a collaboration between the Superconducting Materials Groups at the Materials Science Institute of Barcelona (ICMAB-CSIC) and the NCD-SWEET beamline at ALBA synchrotron light source. The research work will be carried out at Alba premises and the successful candidate will become a beamline researcher of NCD-SWEET beamline. He/she will also participate in the activities of maintenance and upgrade of the beamline instrumentation and will have access to additional in-house beam time allocated to the project described above.
The project aims to engage a skilled researcher with experience in synchrotron hard X-ray diffraction and/or surfaces scattering (GIWAXS) with interest in in-situ fast acquisition processes and evaluation of combinatorial samples. He/she will be the Experiment Operator.
