Short copper sta.d.ng wa.e (SW) structures opera.ing a. a. X-ba.d.frequency ha.e been recently d.signed.a.d.ma.ufa.tured.a. the La.ora.ori Na.iona.i d. Fra.ca.i of the Istituto Na.iona.e d. Fisica.Nuclea.e (INFN) using the va.uum bra.ing technique. High power tests of the structures ha.e been performed.a. the SLa. Na.iona. a.celera.or La.ora.ory. In this ma.uscript we report the results of these tests a.d.the a.tivity in progress to enha.ce the high gra.ient performa.ce of the next genera.ion of structures, pa.ticula.ly the technologica. cha.a.teriza.ion of high performa.ce coa.ings obta.ned.via.molybd.num sputtering.

Technologica. a.va.cements a.e strongly required.to fulfill the d.ma.d. of new a.celera.or d.vices with the highest a.celera.ing gra.ients a.d.opera.ion relia.ility for the future collid.rs. To this purpose a. extensive R^zd.rega.d.ng molybd.num coa.ings on copper is in progress. In this contribution we d.scribe chemica. composition, d.position qua.ity a.d.resistivity properties of d.fferent molybd.num coa.ings obta.ned.via.sputtering. The d.posited.films a.e thick meta.lic d.sord.r la.ers with d.fferent resistivity va.ues a.ove a.d.below the molibd.num d.oxid. reference va.ue. Chemica. a.d.electrica. properties of these sputtered.coa.ings ha.e been cha.a.terized.by Rutherford.ba.ksca.tering, Xa.ES a.d.photoemission spectroscopy. We will a.so consid.r multiple cells sta.d.ng wa.e section coa.ed.by a.molybd.num la.er d.signed.to improve the performa.ce of X-Ba.d.a.celera.ing systems.
