To enhance the signal-to-noise ratio of backlighting under limited picosecond laser energy conditions, an online hard x-ray detector with high detection efficiency and gating capability is required to mitigate interference from long-duration x-ray pulses. To address this, we developed a dual microchannel plate (MCP) gated image intensifier system. MCP devices with varying specifications, containing 37% and 51% lead by weight, were fabricated and integrated into image intensifiers for detective quantum efficiency testing. The results showed that the dual MCP image intensifier with 37% lead achieved a maximum detective quantum efficiency of \u223c4.48%, comparable to that of the AXIS system at the National Ignition Facility as reported in literature. Furthermore, the dual MCP image intensifier with 51% lead demonstrated a significantly higher quantum detection efficiency of 7.15%. Experiments conducted at the ShenGuang-II upgraded facility tested the spatial resolution and gating functionality of the dual MCP gated image intensifier, revealing a spatial resolution of 2.09 lp\/mm and effective suppression of nanosecond-long x-ray interference.<\/jats:p>","DOI":"10.1063\/5.0316735","type":"journal-article","created":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T12:41:56Z","timestamp":1773837716000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Dual MCP gated image intensifier for online high-energy x-ray detection"],"prefix":"10.1063","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3986-491X","authenticated-orcid":false,"given":"Feng","family":"Zhang","sequence":"first","affiliation":[{"name":"National Key Laboratory of Plasma Physics, Laser Fusion Research Center (LFRC), China Academy of Engineering Physics (CAEP) 1 , Mianyang 621900,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7092-3789","authenticated-orcid":false,"given":"Lianqiang","family":"Shan","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Plasma Physics, Laser Fusion Research Center (LFRC), China Academy of Engineering Physics (CAEP) 1 , Mianyang 621900,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3840-3668","authenticated-orcid":false,"given":"Penghui","family":"Feng","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Ultrafast Optical Science and Technology, Xi\u2019an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences 2 , Xi\u2019an 710119,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minghai","family":"Yu","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Plasma Physics, Laser Fusion Research Center (LFRC), China Academy of Engineering Physics (CAEP) 1 , Mianyang 621900,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zongqiang","family":"Yuan","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Plasma Physics, Laser Fusion Research Center (LFRC), China Academy of Engineering Physics (CAEP) 1 , Mianyang 621900,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao","family":"Tian","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Plasma Physics, Laser Fusion Research Center (LFRC), China Academy of Engineering Physics (CAEP) 1 , Mianyang 621900,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Yang","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Plasma Physics, Laser Fusion Research Center (LFRC), China Academy of Engineering Physics (CAEP) 1 , Mianyang 621900,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1817-9833","authenticated-orcid":false,"given":"Yongsheng","family":"Gou","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Ultrafast Optical Science and Technology, Xi\u2019an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences 2 , Xi\u2019an 710119,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2633-9171","authenticated-orcid":false,"given":"Zhongjin","family":"Chen","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Plasma Physics, Laser Fusion Research Center (LFRC), China Academy of Engineering Physics (CAEP) 1 , Mianyang 621900,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5474-7511","authenticated-orcid":false,"given":"Weimin","family":"Zhou","sequence":"additional","affiliation":[{"name":"National Key Laboratory of Plasma Physics, Laser Fusion Research Center (LFRC), China Academy of Engineering Physics (CAEP) 1 , Mianyang 621900,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6979-4556","authenticated-orcid":false,"given":"Yuqiu","family":"Gu","sequence":"additional","affiliation":[{"name":"Shanghai Institute of Laser Plasma, China Academy of Engineering Physics (CAEP) 3 , Shanghai 201800,","place":["China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2026,3,18]]},"reference":[{"key":"2026031808415460600_c1","doi-asserted-by":"publisher","first-page":"101102","DOI":"10.1016\/j.hedp.2024.101102","volume":"51","year":"2024","journal-title":"High Energy Density Phys."},{"issue":"4","key":"2026031808415460600_c2","doi-asserted-by":"publisher","first-page":"041102","DOI":"10.1063\/5.0130689","volume":"94","year":"2023","journal-title":"Rev.
