Abstract: A scheme of the new frequency standard is reported based on a microwave transition between hyperfine components of the ground state in ²⁵Mg⁺ ions. It is proposed to capture ions into a linear quadrupole Paul trap and to perform the laser cooling, as well as to prepare the particle ensemble and to implement detection by using a single laser system based on a semiconductor laser. Characteristics of the suggested frequency standard are estimated.

Keywords: microwave frequency standard, ²⁵Mg⁺ ions.
