Abstract
Three graphite tiles coated with B4C were mounted in the X-point strik e region of JET during operations in 1991. The coatings remained adher ent, though areas reached temperatures at which local melting occurred . Boron and deuterium analyses in the area surrounding the tiles sugge st sublimation of boron was an important release mechanism, and that t he region between the strike zones (the private flux region) is a majo r redeposition area.
