Therefore PNDetector invented the so called Racetrack chip structure. These SDDs make use of an oval shaped active area. Therefore, they can be placed extremely close to the sample even in applications where the available space is restricted. This leads to largely increased solid angles.<\/p>\n \u5982\u679c\u4ec5\u589e\u52a0SDD\u7684\u6d3b\u52a8\u533a\u57df\uff0c\u5219\u5b58\u5728\u9650\u5236\u3002\u56e0\u6b64PNDetector\u53d1\u660e\u4e86Racetrack\u82af\u7247\u7ed3\u6784\u3002\u8fd9\u4e9bSDD\u5229\u7528\u4e86\u4e00\u4e2a\u692d\u5706\u5f62\u7684\u6d3b\u52a8\u533a\u57df\u3002\u56e0\u6b64\uff0c\u5373\u4f7f\u5728\u53ef\u7528\u7a7a\u95f4\u6709\u9650\u7684\u5e94\u7528\u4e2d\uff0c\u5b83\u4eec\u4e5f\u53ef\u4ee5\u653e\u7f6e\u5728\u79bb\u6837\u54c1\u975e\u5e38\u8fd1\u7684\u4f4d\u7f6e\u3002\u8fd9\u5bfc\u81f4\u7acb\u4f53\u89d2\u5927\u5927\u589e\u52a0\u3002<\/p>\n High resolution spectroscopy down to\u00a0126 eV<\/strong>\u00a0@ Mn K\u03b1, -30 \u00b0C<\/p>\n<\/li>\n Extreme close proximity to the sample with solid angles exceeding 1 sr<\/p>\n<\/li>\n Huge solid angles up to 2 sr are possible with dual configurations in TEM<\/p>\n<\/li>\n Mounted on a compact housing comprising non-magnetic materials<\/p>\n<\/li>\n Mostly used in \u201cwindowless\u201d configuration \u2013 gives the highest detection efficiency for light elements<\/p>\n<\/li>\n<\/ul>\n<\/div>\n <\/p>\n \u7279\u6b8a\u7684\u692d\u5706\u5f62SDD\u7cfb\u5217Racetrack Silicon Drift Detector (SDD) Racetrack SDDs: For large solid angle in Microanalysis in TEM <\/p>\n","protected":false},"author":19,"featured_media":182,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_vp_format_video_url":"","_vp_image_focal_point":[]},"categories":[1],"tags":[8,6,5,3,9,7,4],"yoast_head":"\n<\/p>\n
