That is, where the X-rays hit the sample.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The 04-548 dual anode source typically has one anode side that is Mg and the other side is Al.   The older XPS systems that have an 04-548 X-ray source use a lens on the input to the SCA (Spherical Capacitor Analyzer) which determines the analysis area.  For example the PHI 5600 XPS system can analyze areas as large as 10mm X 4mm down to 75uM.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The actual illumination area of the 04-548 dual anode X-ray source is quite large as shown in this video &#8211; <a href=\"https:\/\/www.youtube.com\/watch?v=qQZGJ_TBeRM&amp;t=8s\"> <\/a><code><a href=\"https:\/\/youtu.be\/qQZGJ_TBeRM\" target=\"_blank\" rel=\"noreferrer noopener\">04-548 X-ray source illumination<\/a><\/code><a href=\"https:\/\/youtu.be\/qQZGJ_TBeRM?si=MkGKMTfeOnObwaq8\"> <\/a>area.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Today&#8217;s state of the art XPS systems focus a small electron beam onto an aluminum target in conjunction with a mono-chromator to excite a very small area on the sample.  Rather than exciting a very large area, today&#8217;s XPS systems excite a very small area. Down to just a few microns which make it possible to image the sample and analyze surface defects.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This blog post includes a video which shows the area of illumination for an 04-548 dual anode X-ray source. <a href=\"https:\/\/www.rbdinstruments.com\/blog\/04-548-dual-anode-x-ray-source-area-of-illumination-excitation\/\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":4129,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false},"categories":[164,160],"tags":[270,457],"class_list":["post-4128","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-general-optics-and-vacuum","category-x-ray-sources","tag-04-548-x-ray-source","tag-area-of-illumination"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/www.rbdinstruments.com\/blog\/wp-content\/uploads\/2024\/12\/04-585-dual-anode-xray-source.webp?fit=442%2C289&ssl=1","jetpack_shortlink":"https:\/\/wp.me\/p2DEXo-14A","jetpack_sharing_enabled":true,"jetpack_likes_enabled":true,"jetpack-related-posts":[],"_links":{"self":[{"href":"https:\/\/www.rbdinstruments.com\/blog\/wp-json\/wp\/v2\/posts\/4128","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.rbdinstruments.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.rbdinstruments.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.rbdinstruments.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.rbdinstruments.com\/blog\/wp-json\/wp\/v2\/comments?post=4128"}],"version-history":[{"count":2,"href":"https:\/\/www.rbdinstruments.com\/blog\/wp-json\/wp\/v2\/posts\/4128\/revisions"}],"predecessor-version":[{"id":4142,"href":"https:\/\/www.rbdinstruments.com\/blog\/wp-json\/wp\/v2\/posts\/4128\/revisions\/4142"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.rbdinstruments.com\/blog\/wp-json\/wp\/v2\/media\/4129"}],"wp:attachment":[{"href":"https:\/\/www.rbdinstruments.com\/blog\/wp-json\/wp\/v2\/media?parent=4128"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.rbdinstruments.com\/blog\/wp-json\/wp\/v2\/categories?post=4128"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.rbdinstruments.com\/blog\/wp-json\/wp\/v2\/tags?post=4128"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
