description

Promocijas darba motivācija ir parādīt lāzerinducētās ablācijas spektroskopijas metodes efektivitāti plazmu skarošo materiālu piemaisījumu analīzei. Promocijas darba uzdevumi ir uzstādīt un palaist ablācijas spektorskopijas iekārtu, un izstrādāt metodiku piemaisījumu dziļuma sadalījuma noteikšanai. Promocijas darbs apraksta ASDEX Upgrade (AUG) tokamaka divertora plākšņu paraugu pētīšanu ar lāzerablācijas spektroskopijas metodi. Ablācijas krāteri tika pētīti ar profilometra palīdzību. Lāzerablācijas spektorskopijas iekārta tika izstrādāta un daļēji izgatavota LU Cietvielu Fizikas institūtā. Atrasti optimālie AUG divertora plākšņu paraugu ablācijas spektroskopijas nosacījumi. Reģistrēti paraugu plazmas emisijas spektri, kas parāda ievērojamu piemaisījumu skaitu. Identificēti piemaisījumu elementi, kā arī noteikti to iespējamie avoti. Izmantojot plazmas spektrus, novērtēti pamatpiemaisījumu akumulācijas dziļumi AUG paraugu virsmā.
