Embodiment 1

[0030] figure 1 It is a flowchart of a hydrogen atom frequency standard ionization bubble aging method.

[0031] The embodiment of the present application provides a hydrogen atom frequency standard ionization bubble aging method, including the following steps:

[0032] Step 101, inject ionized bubbles with 25%-50% concentration of HF solution, and place in a water tank for 30 minutes-1 hour.

[0033] In step 101, select 25%-50% HF solution, use a syringe to fill the bubble body through the air inlet of the ionization bubble, and soak the ionization bubble filled with the acid solution in tap water for 30 minutes to 1 hour between.

[0034] The purpose of soaking the ionization bubble filled with acid solution in tap water is to prevent the acid solution from heating.

[0035] Step 102, washing the HF solution in the ionization bubble with pure water.

[0036] In step 102, the acid solution in the bubble is replaced and washed out with a syringe filled with pure water.

Embodiment 2

[0045] figure 2 It is a flowchart of an embodiment of a hydrogen atom frequency standard ionization bubble aging method.

[0046] Step 101, inject ionized bubbles with 25%-50% concentration of HF solution, and place in a water tank for 30 minutes-1 hour.

[0047] Step 102, washing the HF solution in the ionization bubble with pure water.

[0048] Step 104, washing the inner wall of the ionization bubble with deionized water in a dust-free environment.

[0049] In step 104, the inner wall of the ionization bubble is rinsed with deionized water in a dust-free vacuum environment.

[0050] Since the ionized bubbles have been soaked in the solution containing ions and have been polluted by organic substances, they are rinsed with deionized water to remove the remaining ions on the ionized bubbles.

[0051] The optimal number of deionized water cleaning is three times, less than three times, the effect of removing residual ions is not good, more than three times, the improvement...

[0056] Step 105, inject the ionized bubble into pure water to rinse, and then drain the water.

[0057] In step 105, the ionization bubble is washed with pure water to clean the dust existing in the ionization bubble.

[0058] Rinse the ionization bubble with pure water, the main purpose is to clean the dust and other impurities visible to the naked eye.

[0059] The process of washing the ionized bubbles with pure water is carried out in a water tank filled with pure water.

[0060] Step 101, inject the ionization bubble with 25%-50% concentration of HF solution, and place it in the water tank for 30 minutes-1 hour;

[0061] Step 102, washing the HF solution in the ionization bubble with pure water.

[0062] Step 103, filling the ionization bubble with absolute ethanol, and waiting for the absolute ethanol to volatilize.

Abstract

The invention discloses a hydrogen atom frequency standard ionization bubble aging method. The problems that in the prior art, ionization bubbles take a long time to reach the normal aging brightnessis poor in batch consistency and uncontrollable in product development cycle are solved. The method comprises the following steps that an HF solution with the concentration being 25%-50% is injected into ionization bubbles, and ionization bubbles are placed in a water tank for 30 minutes to 1 hour; the HF solution in the ionization bubbles is washed with pure water; and the ionization bubbles is injected with absolute ethyl alcohol, and an operator waits for evaporation of the absolute ethyl alcohol. Through the hydrogen atom frequency standard ionization bubble aging method, the time requiredfor the ionization bubble to reach a normal working state can be effectively shortened and is shortened to less than two days from longer than a week, the batch aging success rate reaches 100%, raw materials are saved, the cost is reduced, the product quality and labor productivity are improved, and guarantee is provided for control over the hydrogen atom frequency standard development cycle.

Description

technical field [0001] The present application relates to the field of ionization bubble aging, in particular to a hydrogen atom frequency standard ionization bubble aging method. Background technique [0002] At present, the aging method of ionization bubbles used for hydrogen atomic frequency standards is: take the same batch of ionization bubbles that have passed the acceptance check and put them into the aging test bench, and check with the naked eye one by one whether there are granular impurities on the inner wall of each ionization bubble. The granular impurity ionized bubbles are picked out and placed in a sink filled with tap water in advance. Use a syringe to inject 50% HF solution from the air inlet of the ionization bubble to half of the space inside the bubble, take out the syringe and shake the bubble vigorously until the impurities on the inner wall fall off, and use the injection to discharge the 50% HF solution inside the bubble. Fill the whole batch of ion...
