29 A beam of electrons and a beam of protons are accelerated across the same potential difference. They each then undergo diffraction through a crystal lattice to determine their de Broglie wavelength. The de Broglie wavelength of the electron is found to be 3.9 xi$$ 1 0 ^ { - 9 } $$...

A variety of microdomain textures were obtained depending on the energy density of the electron beam, the irradiation time, the dopant and the use of ion-beam thinning prior to electron microscopy. Proton-exchanged specimens are more stable than LiNbO3: Ti, which is in turn more stable than ...

and poorly defined pattern edges. Here, we demonstrate the resist-free, direct X-ray and electron-beam lithography of MOFs. This process avoids etching damage and contamination and leaves the porosity and crystallinity of the patterned MOFs intact. The resulting high-quality patterns have excellent ...
The process begins with resistive evaporation and subsequently transitions to electron-beam evaporation. Evaporation by induction is the focus of the second stage, which is then followed by evaporation through the laser beam. Dealing with vacuum evaporation (P = 1,33.10–1 Pa) and the high vacuum...
For the first stage of a tandem accelerator, an ion source yields a beam of protons, which are accelerated to a low energy by an auxiliary high-voltage supply. This…Read More traveling-wave linear accelerators In particle accelerator: Linear electron accelerators …not survive continuous service)...

Other detection methods rely on the use of RCFs or LANEX fast screens scintillating detectors. On the long run one of the applications of femtoseconds electron and proton bunches is in radiation therapy [21], [22], [23]. It is of interest therefore to see how one can establish a ...
