It uses the existing grounding path on the specimen stage for measuring absorbed current.&nbsp; The small aperture opening of 100\u00b5m and the larger cavity behind the aperture prevent backscatter electrons from escaping. All primary, backscatter and virtually all secondary electrons are absorbed in the EM-Tec B100 Faraday cup. The result is an absorption efficiency of 99% or better for electrons and ions in the 2-30kV range. The EM-Tec B100 Faraday cup is made from brass with overall dimensions of 2.5mm diameter and 2mm high. The aperture hole is 100\u00b5m and the inside cavity dimensions are approximately \u00d81.4&#215;1.5mm<\/p>\n\n\n\n<p>Select point mode on your system and direct the beam into the middle of the hole of the Faraday cup. If the instrument your are using does not include an absorbed current meter, a separate Pico-ammeter needs to be connected.<\/p>\n\n\n\n<table class=\"wp-block-table\"><tbody><tr><th><img decoding=\"async\" width=\"150\" height=\"84\" class=\"wp-image-8661\" style=\"width: 150px;\" src=\"https:\/\/m-s.it\/wp-content\/uploads\/2019\/11\/36-000800-1.jpg\" alt=\"EM-Tec B100 Faraday cup per misurazioni della corrente del fascio\"><\/th><th> <strong>EM-Tec B100 Faraday cup<\/strong> <\/th><\/tr><tr><td><strong>Product # <\/strong><\/td><td><strong>Unit<\/strong> <\/td><\/tr><tr><td><strong>36-000800<\/strong> <\/td><td>each<\/td><\/tr><\/tbody><\/table>\n","protected":false},"featured_media":57007,"parent":0,"template":"","categoria_prodotto":[212],"class_list":["post-10694","prodotti","type-prodotti","status-publish","has-post-thumbnail","hentry","categoria_prodotto-consumables"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
