Non- focused ion beams may be employed to investigate the surface profile and the shape of microscopic objects or periodic surfaces by using the known stopping
One factor of influencing crop growth is the effective elemental contents, especially trace elements, under the circumstances of the same concentrations of N, P
This paper introduces the principles, instrumentation, implementation, and industrial applications of an on- line thermal neutron prompt- gamma element analysis
The large fragment of E.coli DNA polymerase I is imaged by scanning tunneling microscope. The specimen is deposited on highly oriented pyrolytic graphite surfac
A set of equations for investigating transverse instability of a bunch of high current short pulse beam in electron linac is presented, and the result of numeri
