摘要	Beryllium （Be） window is a key component of the ITER radial X-ray camera （RXC）. The Be window presented in this paper has a mechanical clamping structure, the thickness of the Be foil is 80 μm, and the X-ray threshold of the 80 μm Be foil is 1.24 keV. A honeycomb support is designed and applied to strengthen the Be foil to prevent it from breakage when it is exposed to 1 atm perssure. Based on analysis results, the hole diameter of the support is chosen as 4 mm. A metal seal is used to isolate the vacuum on two sides of the Be window, the hollow metal sealing ring ensures the He leakage rate of the Be window being lower than 6× 10^-1 Pa.m^3.s^-1. Baking （240 ℃, 2 h） and vibration（3.3 Hz, 2 h） tests are carried out and the feasibility of the Be window＇s sealant in these situations is tested. The Be window has good stability that can save maintenance cost as well as enhancing the safety of the RXC.
