摘要: This letter demonstrates that ion channeling patterns, produced by the passage of 3 MeV protons through a 0.5 μm thick [001] silicon crystal, can be transported and manipulated to produce enlarged or reduced area patterns using magnetic quadrupole lenses. The different effects on obtained single lenses multiplets are shown. maximum attainable magnification under present conditions is investigated fundamental limitation this process identified as being energy spread gained proton beam it passes crystal.
