Lecture on crystal growth in ILM is on youtube

As part of the teaching activities within the Horizon Europe TWISMA project, Dr. Kheirreddine Lebbou from the Institute of Light and Matter (ILM), University Claude Bernard Lyon 1 (France), presents an overview of his laboratory’s work on the growth of shaped and bulk crystals. The video includes a demonstration of the micro-pulling-down technique for the fabrication of garnet scintillation fibers, showcasing one of the key methods used in advanced scintillator development.

Dr. Kheirreddine Lebbou is an internationally recognised expert in shaped and bulk crystal growth, especially garnet fibres by micro-pulling down (micro-PD), Laser Heating Pedestal Growth (LHPG) methods, as well as bulk crystal growth by the Czochralski technique. He has made significant efforts to develop and improve the performance of different scintillating inorganic oxide crystals by optical spectroscopy, even in the nano-optic domain. A good performance of long Ce-doped garnet fibres and fibre-based detector prototypes was demonstrated by ILM in collaboration with CERN and ISMA in the frame of the H2020 RISE project INTELUM. In particular, an excellent fibre transparency was demonstrated with a light attenuation length of over 1 m. Recently, large (2.5 inch dia.) Gd3Ga5-xAlxO12:Ce (GAGG:Ce) ingots were successfully obtained by the Czochralski technique. Dr. Lebbou has published over 170 scientific papers in highly respected journals on materials science, chemistry, and physics.
