Because of the low frequency and the corresponding long wavelength, the support stem of the drift tube is wound into a spiral. This spiral has a coaxial cooling water guide on the inside up to just before the drift tube. What was soldered 30 years ago was in this case subjected to a galvanic manufacturing process. This additive method allows extreme flexibility in the shape design with corresponding potential for optimising the high-frequency properties.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=&#8221;4.15.1&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.15.1&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_gallery gallery_ids=&#8221;11255,11253&#8243; fullwidth=&#8221;on&#8221; db_images_per_row=&#8221;002&#8243; db_image_max_width=&#8221;100%&#8221; db_image_object_fit=&#8221;contain&#8221; dbdb_version=&#8221;3.8.0&#8243; disabled_on=&#8221;off|off|on&#8221; admin_label=&#8221;Galerie Mobile&#8221; _builder_version=&#8221;4.15.1&#8243; _module_preset=&#8221;default&#8221; custom_margin=&#8221;10px|0px|40px|0px|false|false&#8221; custom_padding=&#8221;10px|0px|10px|0px|false|false&#8221; auto=&#8221;on&#8221; auto_speed=&#8221;3000&#8243; border_width_all=&#8221;10px&#8221; border_color_all=&#8221;#FFFFFF&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_gallery][et_pb_gallery gallery_ids=&#8221;11255,11253&#8243; posts_number=&#8221;999&#8243; db_images_per_row=&#8221;002&#8243; db_image_max_width=&#8221;100%&#8221; db_image_object_fit=&#8221;contain&#8221; dbdb_version=&#8221;3.8.0&#8243; show_title_and_caption=&#8221;off&#8221; show_pagination=&#8221;off&#8221; disabled_on=&#8221;on|on|off&#8221; admin_label=&#8221;Galerie Desktop&#8221; _builder_version=&#8221;4.15.1&#8243; _module_preset=&#8221;default&#8221; custom_margin=&#8221;10px|0px|10px|0px|false|false&#8221; custom_padding=&#8221;10px|0px|10px|0px|false|false&#8221; border_width_all=&#8221;10px&#8221; border_color_all=&#8221;#FFFFFF&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_gallery][\/et_pb_column][\/et_pb_row][et_pb_row admin_label=&#8221;Zeile&#8221; _builder_version=&#8221;4.15&#8243; _module_preset=&#8221;default&#8221; custom_margin=&#8221;0px||||false|false&#8221; custom_padding=&#8221;0px||||false|false&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.15&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text admin_label=&#8221;Text&#8221; _builder_version=&#8221;4.15.1&#8243; _module_preset=&#8221;default&#8221; hover_enabled=&#8221;0&#8243; global_colors_info=&#8221;{}&#8221; sticky_enabled=&#8221;0&#8243;]<\/p>\n<p>For questions or interest &#8211; please <a href=\"https:\/\/www.ntg.de\/en\/firma\/ansprechpartner\/vakuumtechnik-strahldiagnosesysteme-teilchenbeschleuniger\/\" target=\"_blank\" rel=\"noopener\">contact us<\/a><\/p>\n<p>&nbsp;<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n<div class=\"shariff shariff-align-center shariff-widget-align-center\" style=\"display:none\"><ul class=\"shariff-buttons theme-white orientation-horizontal buttonsize-medium\"><li class=\"shariff-button facebook shariff-nocustomcolor\" style=\"background-color:#4273c8\"><a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?u=https%3A%2F%2Fwww.ntg.de%2Fen%2Fbuncher-for-gsi%2F\" title=\"Share on Facebook\" aria-label=\"Share on Facebook\" role=\"button\" rel=\"noreferrernoopener nofollow\" class=\"shariff-link\" style=\"; background-color:#3b5998; color:#3b5998\" target=\"_blank\"><span class=\"shariff-icon\" style=\"fill:#3b5998\"><svg width=\"32px\" height=\"20px\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 18 32\"><path fill=\"#3b5998\" d=\"M17.1 0.2v4.7h-2.8q-1.5 0-2.1 0.6t-0.5 1.9v3.4h5.2l-0.7 5.3h-4.5v13.6h-5.5v-13.6h-4.5v-5.3h4.5v-3.9q0-3.3 1.9-5.2t5-1.8q2.6 0 4.1 0.2z\"\/><\/svg><\/span><span class=\"shariff-text\" style=\"color:#3b5998\">share<\/span>&nbsp;<\/a><\/li><li class=\"shariff-button twitter shariff-nocustomcolor\" style=\"background-color:#1e3050\"><a href=\"https:\/\/twitter.com\/share?url=https%3A%2F%2Fwww.ntg.de%2Fen%2Fbuncher-for-gsi%2F&text=Buncher%20for%20GSI\" title=\"Share on X (Twitter)\" aria-label=\"Share on X (Twitter)\" role=\"button\" rel=\"noreferrernoopener nofollow\" class=\"shariff-link\" style=\"; background-color:#000000; color:#000000\" target=\"_blank\"><span class=\"shariff-icon\" style=\"fill:#000000\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" height=\"1em\" viewBox=\"0 0 512 512\"><!--!
