Guanying: Test the self-trapping of helium atoms in  WVx (x means differnet concentration of V) by modeling.

Zhehao: Talk with Kostas about sampling thin films (W, W, WNbV) to reduce O and C.

Marie-France:  1. Check the posibility of Plasma cleaning

                         2. Different temperatures: RT and 800 C
