Abstract:
In order to get the distribution law of passive hydrogen maser’s high and low energy state atoms at the storage bubble entrance after deflected by the quadrupole state selector, a distribution model much closer to practice is built up. Based on the viewpoint of statistics and the motion law of hydrogen atoms in the quadrupole state selecting system, the three-dimensional distribution density of high and low energy state atoms in the plane with a certain distance from the quadrupole state selector is figured out through numerical calculation method, in which the hydrogen atoms’ emergence velocity distribution is regarded as Maxwell distribution under a certain temperature and the emergence angle is approximately regarded as uniform distribution. Using the distribution model, the mathematic relation between the optimum radius of the storage bubble entrance and focusing distance can be got, which can provide theory evidence for manufacturing of storage bubble and designing of focusing distance, so as to make the high-energy state atoms focused at the utmost and the low-energy state atoms dispersed. Consequently the power of transition signal in the cavity resonator can be increased.
