The reaction between a thermal neutron and a <jats:sup>10<\/jats:sup>B\n  atom releases two secondary particles, namely a <jats:sup>7<\/jats:sup>Li ion and an\n  alpha particle, which due to momentum conservation are emitted in\n  opposite directions, along the same line (back to back). Current\n  boron coated neutron detectors are equipped with <jats:sup>10<\/jats:sup>B films with\n  thicknesses of several micrometers, deposited on very thick\n  substrate plates. However, since the ranges of the <jats:sup>7<\/jats:sup>Li ion and\n  the alpha particle are of few micrometeres in most materials, one of\n  these particles is always lost in the <jats:sup>10<\/jats:sup>B layer or\n  substrate. As such, these detectors lose the ability to reconstruct\n  the reaction line of action and to precisely determine the neutron\n  position, as only one of the two secondary particles tracks can be\n  measured. With the technique now presented, the sum of the <jats:sup>10<\/jats:sup>B\n  layer and the substrate thicknesses is small enough to allow for\n  both secondary particles to escape and ionize the gas in opposite\n  sides of the <jats:sup>10<\/jats:sup>B converter foil. Independent readout\n  structures, one on each side of the <jats:sup>10<\/jats:sup>B converter foil, detect\n  each secondary particle and determine its track centroid and the\n  deposited energy. Since the two secondary particles are emitted back\n  to back, the neutron position can be obtained by combining the\n  information recorded by the two readout structures. Through GEANT4\n  simulations, we verified that the spatial resolution can be\n  significantly improved: our results show that, by using a B<jats:sub>4<\/jats:sub>C\n  layer with a thickness of 1 \u03bcm on a 0.9 \u03bcm Mylar\n  substrate, the spatial resolution can by improved by a factor of\n  eight, compared to conventional detectors with thick <jats:sup>10<\/jats:sup>B\n  detection layers.<\/jats:p>","DOI":"10.1088\/1748-0221\/17\/03\/t03003","type":"journal-article","created":{"date-parts":[[2022,3,22]],"date-time":"2022-03-22T14:55:52Z","timestamp":1647960952000},"page":"T03003","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Improving position resolution of neutron detectors with ultra-thin B<sub>4<\/sub>C foils"],"prefix":"10.1088","volume":"17","author":[{"given":"N.F.V.","family":"Duarte","sequence":"first","affiliation":[]},{"given":"J.S.","family":"Marcos","sequence":"additional","affiliation":[]},{"given":"A.","family":"Antognini","sequence":"additional","affiliation":[]},{"given":"C.","family":"Klauser","sequence":"additional","affiliation":[]},{"given":"S.A.","family":"Felix","sequence":"additional","affiliation":[]},{"given":"C.M.B.","family":"Monteiro","sequence":"additional","affiliation":[]},{"given":"F.D.","family":"Amaro","sequence":"additional","affiliation":[]}],"member":"266","published-online":{"date-parts":[[2022,3,22]]},"reference":[{"key":"bc4ca4238a0b923820dcc509a6f75849b"},{"key":"bc81e728d9d4c2f636f067f89cc14862c","doi-asserted-by":"publisher","DOI":"10.1016\/S1369-7021(11)70139-0"},{"key":"beccbc87e4b5ce2fe28308fd9f2a7baf3"},{"key":"ba87ff679a2f3e71d9181a67b7542122c"},{"key":"be4da3b7fbbce2345d7772b0674a318d5"},{"key":"b1679091c5a880faf6fb5e6087eb1b2dc"},{"key":"b8f14e45fceea167a5a36dedd4bea2543"},{"key":"bc9f0f895fb98ab9159f51fd0297e236d"},{"key":"b45c48cce2e2d7fbdea1afc51c7c6ad26"},{"key":"bd3d9446802a44259755d38e6d163e820"},{"key":"b6512bd43d9caa6e02c990b0a82652dca","doi-asserted-by":"publisher","DOI":"10.1088\/1748-0221\/10\/04\/P04004","article-title":"The TPC method: improving the position resolution of neutron detectors based on MPGDs","volume":"10","author":"Pfeiffer","year":"2015","journal-title":"JINST"},{"key":"bc20ad4d76fe97759aa27a0c99bff6710","doi-asserted-by":"publisher","first-page":"118","DOI":"10.1140\/epjp\/i2015-15118-1","article-title":"GEM-based detectors for thermal and fast neutrons","volume":"130","author":"Croci","year":"2015","journal-title":"Eur.
