FEgen (v.1): Field Emission Distribution Generator Freeware Based on Fowler–Nordheim Equation
نویسندگان
چکیده
This work presents an open-source code, FEgen, that generates initial field emission distributions based on the time-dependent Fowler–Nordheim equation. Current in-demand and beam tracking software—such as ASTRA, IMPACT-T, GPT—do not contain native distribution generator functions suitable for emitted electron phase space analysis. The intuitive graphical user interface of FEgen input files shown to be fully compatible with both ASTRA GPT. Here, detailed application examples demonstrating a subset FEgen’s capabilities are given by creating customized emitter pattern transverse shaping longitudinal dynamic experiments.

Quantum random number generator based on photonic emission in semiconductors.
We report upon the realization of a novel fast nondeterministic random number generator whose randomness relies on the intrinsic randomness of the quantum physical processes of photonic emission in semiconductors and subsequent detection by the photoelectric effect. Timing information of detected photons is used to generate binary random digits-bits. The bit extraction method based on the resta...
متن کاملInvestigation of Some Attacks on GAGE (v1), InGAGE (v1), (v1.03), and CiliPadi (v1) Variants
In this paper, we present some attacks on GAGE, InGAGE, and CiliPadi which are candidates of the first round of the NIST-LWC competition. GAGE and InGAGE are lightweight sponge based hash function and Authenticated Encryption with Associated Data (AEAD), respectively and support different sets of parameters. The length of hash, key, and tag are always 256, 128, and 128 bits, respec...

متن کاملOn the distribution of the power generator
We present a new method to study the power generator of pseudorandom numbers modulo a Blum integer m. This includes as special cases the RSA generator and the Blum–Blum–Shub generator. We prove the uniform distribution of these, provided that the period t ≥ m3/4+δ with fixed δ > 0 and, under the same condition, the uniform distribution of a positive proportion of the leftmost and rightmost bits...
