BackgroundRadio Frequency Quadrupoles (RFQs) are applied widely in proton accelerator facilities. The development of the high-frequency RFQs enables the construction of compact proton accelerator facilities, but faces with more tuning difficulties. T

A real number $x$ is normal with respect to an integer base $b \geq 2$ if its digit expansion in this base is ``equitable'', in the sense that for $k \geq 1$, every ordered sequence of $k$ digits from $\{0, 1, \ldots, b-1\}$ occurs in the digit expan

A real number $x$ is considered normal in an integer base $b \geq 2$ if its digit expansion in this base is ``equitable'', ensuring that for each $k \geq 1$, every ordered sequence of $k$ digits from $\{0, 1, \ldots, b-1\}$ occurs in the digit expans
