In-situ LIBS and NRA deuterium retention study in porous W-O and compact W coatings loaded by Magnum-PSI

•W and W-O coatings with different characteristics were exposed to D plasma.•D retention in these coatings was measured with in-situ LIBS and NRA.•W coatings with low O content had almost the same D retention by NRA and LIBS.•Porous W-O coating had highest D retention while LIBS signal was an order...
