Tungsten coatings were deposited on a silicon substrate by magnetron sputtering process. After a preliminary surface characterization and before studying the gas desorption by LIDS, both types of tungsten samples were exposed to helium plasma in the GyM linear device. A Nd:YAG laser with constant output power leading to a smooth controllable increase of layer temperature was used, resulting in a complete desorption of gases in a point heated by the laser. The desorbed gases were detected up to 200 amu\/e with a QMS (Quadrupole Mass Spectrometer).  The results of the application of LIDS on tungsten targets exposed to a wide range of helium fluxes, fluences, and impact energies under different surface temperatures are presented and compared with Thermal Desorption Spectrometry (TDS) and Laser Induced Breakdown Spectroscopy (LIBS).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Laguardia L.; Iafrati M.; Alonzo M.; Pedroni M.; Vassallo E.; De Angeli M.; Ghezzi F.; Gervasini G.; Uccello A.; Cremona A.; Mellera V.; Rufoloni A.<\/p>\n","protected":false},"featured_media":1294,"comment_status":"closed","ping_status":"open","template":"","meta":[],"product_cat":[707],"product_tag":[1284,1757,3648,3987],"class_list":["post-9062","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-conference-abstracts","product_tag-helium-plasma","product_tag-diagnostics","product_tag-gym-linear-device","product_tag-laser-induced-desorption-spectroscopy-lids","prodpage-style2"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product\/9062","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/comments?post=9062"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media\/1294"}],"wp:attachment":[{"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/media?parent=9062"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_cat?post=9062"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.istp.cnr.it\/it\/wp-json\/wp\/v2\/product_tag?post=9062"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
