报道了一种新型的微机械X射线收集器,该收集器采用各向异性刻蚀的Si(111)侧壁作为X射线反射镜,用于未来的天文任务。该收集器设计用于将ϕ100 mm平行X射线束会聚为ϕ4 mm焦点。为了获得光滑的Si(111)侧壁,在各向异性KOH刻蚀过程中加入了动态冲击波。获得了纳米量级或更小的表面粗糙度。侧壁或X射线反射镜从晶片上切成镜片,然后粘在由深度反应离子刻蚀形成的支架上。在Al Kα1.49keV的ISAS30m长X射线束线上成功地获得了第一个光图像。
A novel micromachined X-ray collector using anisotropically etched Si(111) side walls as X-ray mirrors for future astronomical missions is reported. The collector was designed to converge a ϕ 100mm parallel X-ray beam into a ϕ 4mm focus. In order to obtain smooth Si(111) side walls, dynashock-type ultrasonic waves were added during the anisotropic KOH etching. The surface roughness on the order of nm or less was achieved. The sidewalls or the X-ray mirrors were diced from the wafer as mirror chips and then adhered to a mount formed by deep reactive ion etching. The first light image was successfully obtained at Al Kα 1.49keV in a ISAS 30m-long X-ray beam line.
