Abstract

The invention discloses a method for replicating a large-size thin-walled X-ray focusing mirror, which belongs to the technical field of X-ray focusing mirror processing. The replication method is used to ensure the consistency of a large-scale replication process and improve production efficiency. It includes the following steps: S1. Debugging the demoulding device; installing a mandrel mold with a mirror shell, and debugging the demoulding device; S2. injecting high-purity nitrogen; injecting nitrogen into the sealing cover of the demolding device; S3. injecting liquid nitrogen ;Inject liquid nitrogen into the mandrel mold; S4. Monitor the display of the sensor; during this process, pay attention to monitoring the display values ​​of the force sensor, thermocouple meter, ambient temperature, and humidity, and make a record; S5. Start demoulding; The mold device separates the lens from the mandrel mold; S6. Lifts the lens; Lifts the lens through the lifting device; S7. Unloads the mandrel. The invention only needs the movement of the vertical axis to meet the needs of the replication process, avoids complex motion control, can realize automatic control, saves manpower, improves the overall replication efficiency, and realizes batch replication.

Description

technical field [0001] The invention belongs to the technical field of X-ray focusing mirror processing, in particular to a method for replicating a large-size thin-walled X-ray focusing mirror. Background technique [0002] In order to study the new phenomenon of high-energy radiation from celestial bodies such as black holes and neutron stars, observatories and space centers in many countries and regions led by the United States have launched more than ten X-ray astronomical satellites into space. In 1952, German physicist Hans Wolter designed three Wolter-type X-ray focusing telescopes with grazing incidence that satisfy Abbe's sine conditions, called Wolter III III focusing telescopes. The Wolter-I X-ray telescope is composed of a parabolic internal mirror and a hyperboloid internal mirror. Its advantage is that it can be nested in multiple layers, which is conducive to weak source observation. China's next-generation flagship X-ray astronomical satellite, the Enhanced ...
