چکیده انگلیسی
It has been demonstrated that characters can be written by proton beams in various materials. In contributing to the rapid development of proton beam writing technology, we introduce a new method for binary code storage and data encryption by writing binary codes of characters (BCC) in substrates with single proton beam writing technology. In this study, two kinds of BCC (ASCII BCC and long bit encrypted BCC) were written in CR-39 by a 2.6Â MeV single proton beam. Our results show that in comparison to directly writing character shapes, writing ASCII BCC turned out to be about six times faster and required about one fourth the area in substrates. The approach of writing long bit encrypted BCC by single proton beams supports preserving confidential information in substrates. Additionally, binary codes fabricated by MeV single proton beams in substrates are more robust than those formed by lasers, since MeV single proton beams can make much deeper pits in the substrates.
