Embodiment Construction

[0025] A kind of fast pneumatic protection optical pumping bubble device and experimental method of the present invention are described in further detail below in conjunction with accompanying drawing:

[0026] Such as figure 1 As shown, a fast pneumatic protection optical pumping bubble device includes an oxygen detection device and a valve control device. The oxygen content in the hyperpolarized inert gas raw material gas is detected by the oxygen detection device, and a control signal is sent to the valve control device. When the raw material When the oxygen content in the gas exceeds the preset threshold value of the oxygen detection device, the valve control device will simultaneously close the air inlet and outlet of the optical pumping bubble.

[0027] Such as figure 2 As shown, a fast pneumatic protection optical pumping bubble device includes optical pumping bubble 1, first pneumatic valve 2, second pneumatic valve 3, solenoid valve 4, trace oxygen analyzer 5, solid...

Abstract

The invention discloses a rapid pneumatic optical pumping bubble protecting device. According to the rapid pneumatic optical pumping bubble protecting device, a trace oxygen analyzer monitors the connect of oxygen in raw gases of a hyperpolarizing inert gas system, when the content of oxygen exceeds a set threshold, the tract oxygen analyzer sends a triggering signal, so that after being switched on, an electromagnetic valve is triggered through high-pressure gases and is connected with a first pneumatic valve of an optical pumping bubble gas inlet end and a second pneumatic valve of an optical pumping bubble gas outlet end, and the first pneumatic valve and the second pneumatic valve are made to be closed at the same time. In this way, the effect that an optical pumping bubble is prevented from being polluted by oxygen is achieved.

Description

technical field [0001] The invention relates to the field of atomic and molecular physics devices, in particular to a device for quickly protecting a reaction vessel when the oxygen content exceeds the system threshold by means of an oxygen detection device and a valve control device, which is suitable for hyperpolarized inert gas systems and used to protect light Pump the bubble to protect it from contamination by excessive oxygen in the system feed gas. Background technique [0002] The hyperpolarized inert gas technology using the principle of spin exchange optical pumping was gradually developed by the laboratory of Professor Happer of Princeton University in the United States. The main principle is that the outermost electrons of alkali metals are excited to high energy under the action of laser light. At this time, the outermost electrons of the alkali metal atoms have a high degree of polarization, and then the alkali metal atoms and the inert gas atoms in the system ...
