Since the resistance of the SMA connectors and the input impedance of most high-speed analyzers is 50 \u03a9, it is essential that the detector impedance is the same. To match the amplifier input impedance, VTC \u201cBaspik\u201d TOF detectors use a cone-shaped anode, in which the transition from the anode active surface to the inner diameter of the wire inside the coaxial cable through the SMA connector is smooth.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/baspik.com\/wp-content\/uploads\/2025\/06\/veu-7bk-1-1024x667.webp\" alt=\"\" class=\"wp-image-3691\" style=\"width:429px;height:auto\"\/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Specification<\/h3>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h5 class=\"wp-block-heading\">The detector electrical connection diagram<\/h5>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"273\" height=\"302\" src=\"https:\/\/baspik.com\/en\/wp-content\/uploads\/sites\/5\/2025\/06\/veu-7bk-1-2-en.webp\" alt=\"\" class=\"wp-image-3192\" style=\"width:309px;height:auto\" srcset=\"https:\/\/baspik.com\/en\/wp-content\/uploads\/sites\/5\/2025\/06\/veu-7bk-1-2-en.webp 273w, https:\/\/baspik.com\/en\/wp-content\/uploads\/sites\/5\/2025\/06\/veu-7bk-1-2-en-271x300.webp 271w\" sizes=\"auto, (max-width: 273px) 100vw, 273px\" \/><\/figure>\n\n\n\n<p><em>R1<\/em> = 2M\u03a9;<em> R2<\/em> =300 k\u03a9;<em> R3 <\/em>= 100 k\u03a9 \u00f7 1 \u041c\u03a9<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h5 class=\"wp-block-heading\">Shape of the detector output pulse<\/h5>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/baspik.com\/wp-content\/uploads\/2025\/06\/veu-7bk-1-3.webp\" alt=\"\" class=\"wp-image-3693\" style=\"width:290px;height:auto\"\/><\/figure>\n\n\n\n<p>The detector with a cone anode provides an output pulse of short width without attenuated oscillations<\/p>\n<\/div>\n<\/div>\n\n\n\n<h5 class=\"wp-block-heading\">Basic parameters<\/h5>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Parameter<\/th><th>Value<\/th><\/tr><\/thead><tbody><tr><td>MCP channel diameter (\u00b5m)<\/td><td>10<\/td><\/tr><tr><td>Active area diameter (mm)<\/td><td>26<\/td><\/tr><tr><td>MCP quantity<\/td><td>2<\/td><\/tr><tr><td>Pulse height (ps) (max)<\/td><td>900<\/td><\/tr><tr><td>Pulse leading edge rise time (\u0440s)<\/td><td>450<\/td><\/tr><tr><td>Gain<\/td><td>1\u00d710<sup>7<\/sup><\/td><\/tr><tr><td>Pulse height resolution, % (max)<\/td><td>135<\/td><\/tr><tr><td>Count rate density (max.)
