The scattering source is a 1\u00a0MW, 105\u00a0GHz gyrotron, chosen to avoid both absorption and cutoff within the burning plasma. Scattered signals are collected by seven front-end receivers spanning 100\u2013110\u00a0GHz, each positioned at a different scattering angle. A 105\u00a0GHz notch filter with &amp;gt;60 dB depth protects the receivers from unscattered power, while a WR-10 bandpass filter rejects 170\u00a0GHz electron cyclotron heating signals. A 96\u00a0GHz high-pass filter enables single-sideband operation, and image rejection filters allow downconversion using a 100\u00a0GHz local oscillator to an intermediate frequency range of 2\u201312\u00a0GHz. The seven front-end receiver modules provide &amp;gt;30 dB conversion gain. The back-end electronics comprise 28 radiometer modules that generate 448 frequency channels, with high-resolution (100\u00a0MHz spacing) and low-resolution (190\u00a0MHz spacing) configurations optimized for bulk ion and fast-ion measurements, respectively. Detailed sensitivity analysis, accounting for system losses, receiver noise, and expected plasma emission, predicts a signal-to-noise ratio of &amp;gt;10 for the bulk ion feature and &amp;gt;5 for the fast-ion tails under nominal operating conditions, demonstrating the diagnostic\u2019s viability. The CTS diagnostic is predicted to achieve a spatial resolution of \u223c5\u00a0cm and a time resolution of 80\u00a0ms, sufficient to resolve alpha-particle slowing-down dynamics.<\/jats:p>","DOI":"10.1063\/5.0349935","type":"journal-article","created":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T12:43:49Z","timestamp":1791290629000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Collective Thomson scattering electronics for a burning plasma device"],"prefix":"10.1063","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2882-9385","authenticated-orcid":false,"given":"Pengjun","family":"Sun","sequence":"first","affiliation":[{"name":"Institute of Plasma Physics, Chinese Academy of Sciences 1 , Hefei, Anhui 230031,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6892-358X","authenticated-orcid":false,"given":"Haiqing","family":"Liu","sequence":"additional","affiliation":[{"name":"Institute of Plasma Physics, Chinese Academy of Sciences 1 , Hefei, Anhui 230031,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8080-7773","authenticated-orcid":false,"given":"Calvin","family":"Domier","sequence":"additional","affiliation":[{"name":"University of California Davis 2 , Davis, California 95616,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-1766-0836","authenticated-orcid":false,"given":"Xinhang","family":"Xu","sequence":"additional","affiliation":[{"name":"University of California Davis 2 , Davis, California 95616,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-5308-9990","authenticated-orcid":false,"given":"Hsiangying","family":"Lai","sequence":"additional","affiliation":[{"name":"University of California Davis 2 , Davis, California 95616,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-1211-0772","authenticated-orcid":false,"given":"Logan","family":"Himes","sequence":"additional","affiliation":[{"name":"University of California Davis 2 , Davis, California 95616,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-5554-1686","authenticated-orcid":false,"given":"Jon","family":"Dannenberg","sequence":"additional","affiliation":[{"name":"University of California Davis 2 , Davis, California 95616,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-4852-0766","authenticated-orcid":false,"given":"Baron","family":"Li","sequence":"additional","affiliation":[{"name":"University of California Davis 2 , Davis, California 95616,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-8992-8493","authenticated-orcid":false,"given":"Khadija","family":"Rahman","sequence":"additional","affiliation":[{"name":"University of California Davis 2 , Davis, California 95616,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-9075-0149","authenticated-orcid":false,"given":"Xiaoliang","family":"Li","sequence":"additional","affiliation":[{"name":"Future Energy Acceleration and Translation (FEAT), Agency for Science, Technology and Research (A*STAR) 3 , 2 Fusionopolis Way, Innovis #08-03, Singapore 138634,","place":["Republic of Singapore"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-0111-9285","authenticated-orcid":false,"given":"Jacob","family":"Farias-Hesson","sequence":"additional","affiliation":[{"name":"University of California Davis 2 , Davis, California 95616,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2842-8474","authenticated-orcid":false,"given":"Yilun","family":"Zhu","sequence":"additional","affiliation":[{"name":"University of California Davis 2 , Davis, California 95616,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2026,10,6]]},"reference":[{"key":"2026100608434152000_c1","doi-asserted-by":"publisher","first-page":"398","DOI":"10.1038\/nphys3745","volume":"12","year":"2016","journal-title":"Nat.
