The Wire

A new combined field ionisation/electron impact ion source is described which can be used in connection with a direct inlet probe. The distance between the electron beam and the wire emitter is only one mm, sot hat the vapour of the sample reaches both ionizing zones. The vapour passes the ion source as a quasi molecular beam. Results obtained with this source will be given.

Ion Beam Sputter Deposition

The in situ electron microscope technique has been shown to be a powerful method for investigating the nucleation and growth of thin films formed by vacuum vapor deposition. The nucleation and early stages of growth of metal deposits formed by ion beam sputter-deposition are now being studied by the in situ technique.A duoplasmatron ion source and lens assembly has been attached to one side of the universal chamber of an RCA EMU-4 microscope and a sputtering target inserted into the chamber from the opposite side. The material to be deposited, in disc form, is bonded to the end of an electrically isolated copper rod that has provisions for target water cooling. The ion beam is normal to the microscope electron beam and the target is placed adjacent to the electron beam above the specimen hot stage, as shown in Figure 1.
