Ultra-precision manufacture of X-ray focusing mirror

Simulation and experimental study of replication of x-ray focusing mirrors

“…[7] Our team uses the independently explored nickel-based electroforming replication process route for manufacturing metal focusing mirrors (as shown in Figure 1). [8] The demolding process is the core link of X-ray focusing mirrors manufacturing, and it is the key process to ensure the accuracy of the focusing mirrors replication. How to quickly, reliably, non-destructively and controllably demolding has been the focus and difficulty of focusing mirrors manufacturing.…”

Diamond turning and full-frequency band error measurement methods for x-ray focusing mirror molds

“…The universe is filled with a large number of transient sources and explosive celestial bodies, whose activities radiate huge high-energy rays such as X-rays and γ radiation 1 . By observing these rays, the physical essence, the laws involved in the evolution of celestial bodies and the formation of dense celestial bodies can be understood.…”

“…Currently, the discovered temporary sources and explosive celestial bodies are only the tip of the iceberg in the universe, requiring more X-ray astronomical detection equipment with larger field of view, higher sensitivity and resolution 2 . For this reason, the Chinese Academy of Sciences has proposed the EP satellite and the eXTP space observatory, aiming to study the high-energy state of matter under the extreme density, gravity and magnetism generated by the strong magnetic field systems, such as binary stars, neutron star, magnetic stars, and supermassive black holes [1][2][3][4][5] .…”

“…1 Working principle of Wolter-I focusing mirror 6 Fig. 2 Wolter-I focusing mirror assembly of EP identification module 1 Electroforming replication is a method of reproducing mirrors by coating the mold surface, electroforming mirrors, and separating the mirror and the mold. The mold can be reused, thus allowing for the mass production of high surface quality mirrors, greatly reducing the cost and cycle time.…”

Simulation of precision bonnet processing with considering edge effect for the x-ray grazing incidence mirror molds

“…It can meet the performance requirements of x-ray telescope through precision fabricating and nesting in groups. The imaging performance of the mirrors is determined largely by the shape accuracy of the mandrels [4][5].…”
