Paper Abstract

We have developed a new method to make very thin mirror for the high throughput X-ray telescope, whose design goal of an angular resolution is 1 arc min half power diameter. In this method, aluminum mirror substrate is figured by diamond machining using special support made of water-soluble adhesive. The smooth surface is obtained by dip lacquering and the reflective layer is gold coated on this surface by the vacuum deposition. By means of this method, we have made test conical mirrors with a diameter of 150 mm, a height of 100 mm, a grazing angle of 0.6 degree and various thickness. We found that this method can provide very thin substrate of thickness down to 0.3 mm. The first results of mechanical and X-ray test indicate that angular resolution is 1.7 arc min half power diameter for 2 stage conical mirror system.
