Plasmas in machines with all metal plasma facing components have a lower Zeff. less radiation cooling in the scrape-off layer and divertor regions and are prone to impurity accumulation in the core. Higher gas puff and the seeding of low-Z impurities are applied to prevent impurity accumulation. to increase the frequency of edge localised modes and to cool the divertor. https://ttgrjjcz4h8l3x.nizarblog.com/35079752/inclusive-fitness-affects-both-prosocial-and-antisocial-behavior-target-gender-and-insult-domain-moderate-the-link-between-genetic-relatedness-and-aggression
