The high-Z impurity accumulation in the plasma core could degrade the plasma performance and may affect sawtooth crash and trigger tearing modes (TMs) in experimental advanced superconducting tokamak (EAST). Triggering of m/n = 3/2 TM (m and n are the poloidal and toroidal mode numbers. respectively) and m/n = 2/1 TM by a large sawtooth crash is observed and studied under the conditio... https://poolsproductscanadas.shop/product-category/vinyl-patch-kits/
