摘要：

We have been developing high throughput X-ray telescope for hard X-ray region (20-40 keV) using Pt/C multilayer supermirrors for balloon borne experiment launched in 2001 June. The Waiter type I telescope consists of about 2,000 supermirrors coated on very thin (150 mum) aluminum foils. We started mass production of the supermirror reflectors. Two different method is used for fabrication process. One is multilayer deposition on the platinum replica foil, and the other is direct replication of supermirror. The performance of the supermirrors are measured in X-ray beam line in Nagoya University and synchrotron radiation facility SPring-8. We obtained 30% reflectivity at 30 keV, corresponding to 0.35 nm interfacial roughness by Debye-Wailer factor. The performance of multilayer supermirrors indicate that we can achieve about 100 cm(2) effective area for a telescope.
