Abstract :
In this paper, development of a new control system for the growth of crystals by Czochralski and potential impact on crystal quality are presented. This research has been carried out as an aspect of optimization for the growth of high-quality large diameter langasite type crystals. Initial results and experimental setup for LGT (La3 Ga5.5Ta0.5O14) are discussed
