m pumping system, then all outgassing must take place before isolation from the pumping system. Rotating anode x-ray tubes, which are high-voltage and high-vacuum devices and require a high-vacuum operating environment, do not operate with constant pumping, and it is therefore required to have all c

I. Dietrichthews, and “Surface Modification and Mechanisms,” by Totten and Liang. A more general approach to friction has been proposed by Nosonovsky and Mortazavi (2014), considering friction and the associated processes of wear as a universal and general phenomenon, independent of how the friction is generat

I. Dietrichted through the film. The AES method, as well as others that use spectrometry, rely on sputtering-rate curves of a similar material of known thickness and sputtering time. Typically a surface chemistry-sensitive method such as X-ray photoelectron spectroscopy (XPS) is needed to help interpret the AE

I. Dietrichd. First, we set up the virtual work inequality, and it is shown that it is implied by the boundary conditions of contact. Then the complementary virtual work inequality is postulated, and it is shown that it implies the boundary conditions of contact. Elasticity is introduced into both inequalities

Historical Survey,ron circuit magnet inside the microscope. Also described is a magnetization device outside the microscope for exciting the ring. The cooled part of the apparatus, the magnetized superconducting ring in its helium container, has to be introduced into the microscope. A shim coil is added for focusing.

Book 1976since the author is little acquainted with the details of the projects. Furthermore, the number of experiments as yet carried out is small. In Appendix B, electron microscope studies of basic superconductor phenomena are reviewed. This material is included, even though it is only slightly connected
