Abstract
The Hot Universe Baryon Surveyor (HUBS) mission will carry a nested X-ray telescope for covering an energy range from 0.5 keV to 10 keV to study the hot baryon evolution. In this paper, we report the last progress of the nested X-ray telescope. For HUBS mission, a three-stage conic-approximation type has been designed, which could simplify the manufacturing process. Then the substrate of the reflective mirror is made by thermal glass slumping technology. The coatings are characterized by a roughness RMS of 0.3 nm, as well as expected high reflectivity and good thermal stability. In addition, the in-situ measurement system program was developed to guide the telescope assembly process, providing a high reliability.
