However, despite a huge effort to improve the technological process, CZT detectors\u2019 full potential has not been completely exploited when both high spatial and energy resolution are required by the application, especially at low energies (&lt;10 keV), limiting their application in energy-resolved photon counting (ERPC) systems. This gap can also be attributed to the lack of dedicated front-end electronics which can bring out the best in terms of detector spectroscopic performances. In this work, we present the latest results achieved in terms of energy resolution using SIRIO, a fast low-noise charge sensitive amplifier, and a linear-array pixel detector, based on boron oxide encapsulated vertical Bridgman-grown B-VB CZT crystals. The detector features a 0.25-mm pitch, a 1-mm thickness and is operated at a \u2212700-V bias voltage. An equivalent noise charge of 39.2 el. r.m.s. (corresponding to 412 eV FWHM) was measured on the test pulser at 32 ns peaking time, leading to a raw resolution of 1.3% (782 eV FWHM) on the 59 keV line at room temperature (+20 \u00b0C) using an uncollimated 241Am, largely improving the current state of the art for CZT-based detection systems at such short peaking times, and achieving an optimum resolution of 0.97% (576 eV FWHM) at 1 \u00b5s peaking time. The measured energy resolution at the 122 keV line and with 1 \u00b5s peaking time of a 57Co raw uncollimated spectrum is 0.96% (1.17 keV). These activities are in the framework of an Italian collaboration on the development of energy-resolved X-ray scanners for material recycling, medical applications, and non-destructive testing in the food industry.<\/jats:p>","DOI":"10.3390\/s23042167","type":"journal-article","created":{"date-parts":[[2023,2,15]],"date-time":"2023-02-15T02:01:10Z","timestamp":1676426470000},"page":"2167","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Advances in High-Energy-Resolution CdZnTe Linear Array Pixel Detectors with Fast and Low Noise Readout Electronics"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7882-6879","authenticated-orcid":false,"given":"Filippo","family":"Mele","sequence":"first","affiliation":[{"name":"Department of Electronics, Information and Bioengineering (DEIB), Politecnico di Milano, Via Anzani 42, 22100 Como, Italy"},{"name":"National Institute of Nuclear Physics (INFN), Sezione di Milano, Via Celoria 16, 22133 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1140-5006","authenticated-orcid":false,"given":"Jacopo","family":"Quercia","sequence":"additional","affiliation":[{"name":"Department of Electronics, Information and Bioengineering (DEIB), Politecnico di Milano, Via Anzani 42, 22100 Como, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9633-6606","authenticated-orcid":false,"given":"Leonardo","family":"Abbene","sequence":"additional","affiliation":[{"name":"Department of Physics and Chemistry (DiFC)\u2014Emilio Segr\u00e8, University of Palermo, Viale delle Scienze, Edificio 18, 90128 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giacomo","family":"Benassi","sequence":"additional","affiliation":[{"name":"Due2lab s.r.l., Via Paolo Borsellino 2, 42019 Scandiano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4062-3782","authenticated-orcid":false,"given":"Manuele","family":"Bettelli","sequence":"additional","affiliation":[{"name":"IMEM-CNR, Parco Area delle Scienze 37\/A, 43100 Parma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7188-3651","authenticated-orcid":false,"given":"Antonino","family":"Buttacavoli","sequence":"additional","affiliation":[{"name":"Department of Physics and Chemistry (DiFC)\u2014Emilio Segr\u00e8, University of Palermo, Viale delle Scienze, Edificio 18, 90128 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2787-0877","authenticated-orcid":false,"given":"Fabio","family":"Principato","sequence":"additional","affiliation":[{"name":"Department of Physics and Chemistry (DiFC)\u2014Emilio Segr\u00e8, University of Palermo, Viale delle Scienze, Edificio 18, 90128 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6916-2716","authenticated-orcid":false,"given":"Andrea","family":"Zappettini","sequence":"additional","affiliation":[{"name":"IMEM-CNR, Parco Area delle Scienze 37\/A, 43100 Parma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7283-021X","authenticated-orcid":false,"given":"Giuseppe","family":"Bertuccio","sequence":"additional","affiliation":[{"name":"Department of Electronics, Information and Bioengineering (DEIB), Politecnico di Milano, Via Anzani 42, 22100 Como, Italy"},{"name":"National Institute of Nuclear Physics (INFN), Sezione di Milano, Via Celoria 16, 22133 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Garavelli, B., Pozzi, P., Macera, D., Zanotti, L., Mencarelli, A., Bubba, G., Bertoni, P., Sammartini, M., Bettelli, M., and Bertuccio, G.
