Abstract

PURPOSE:To manufacture a rubidium gas cell simply, and to increase the resonance intensity of a cavity by providing the inside of the cavity with the square-shaped rubidium gass cell and mounting at least one movable member penetrating the wall surface of the cavity. CONSTITUTION:A square-shaped rubidium gas cell 2 is arranged into a cylindrical cavity 1. At least one frequency adjusting member 3 is mounted to the wall surface of the cavity in order to adjust resonance frequency. The member 3 is constituted by a bar penetrating the wall surface of the cavity 1 and a metallic plate 4, which is set up at the nose of the bar and made of copper of high conductivity, and frequency is adjusted by vertically moving the bar. The cavity 1 and the tuning bar are screwed, and structure in which minute adjustment is enabled is formed. The metallic plate 4 is mounted in order to change the sensitivity of tuning, and its area is set on manufacture so that a proper sensitivity is acquired.

度が低下するという欠点がある。The a+ cassell 1 nervidium atomic annular device uses a single-sided cavity that makes full use of atomic resonance, so there is a risk of misalignment of the 7'L round cassell inserted into the cavity. There are 8 decisions to enshrine the frequency. Such adjustment of the resonance frequency is achieved by inserting and removing a member that penetrates the wall of the cavity into two recesses provided in the cell wall so as to be symmetrical with respect to the central axis of the gas cell.
It is being done. However, in this frequency adjustment method, a recess must be provided on the circumferential surface of the cassell, making it difficult to manufacture the cassell.Also, since the contact area between the cavity wall and the gas cell is large, the resonance strength is low. The disadvantage is that it decreases.

It consists of a rod that passes through the wall of the cavity 1, and a plate 4 with good conductivity, such as copper, attached to the tip of the rod, and the frequency is adjusted by moving the rod up and down. . Cavity 1 and the tuning part are screwed, allowing for minute adjustments. The metal plate 4 is provided to vary the tuning feeling, and the area is set during manufacturing to avoid excessive sensitivity.
