The key changes to the previously fielded system are a redesigned set of thin foil filters in front of the scintillators and individual neutral density filters for each region of the detector. The fully implemented PXTD system can provide unique information about the evolution of ion and electron temperatures in multi-ion and kinetic-physics experiments, proton radiography experiments, and DT experiments executed at the OMEGA facility. The system has 35\u00a0ps time resolution and negligible relative timing uncertainty between measured emission history signals. The first use of the upgraded four-channel PXTD system during a set of D3He-filled silica-glass implosions on OMEGA captured electron temperatures with a minimum uncertainty of 0.5\u00a0keV and resolved both the relative timings and widths of neutron, proton, and x-ray peaks within a single recorded image.<\/jats:p>","DOI":"10.1063\/5.0325451","type":"journal-article","created":{"date-parts":[[2026,7,15]],"date-time":"2026-07-15T12:50:39Z","timestamp":1784119839000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["The next-generation particle x-ray temporal diagnostic for simultaneous time-resolved measurements of nuclear-burn and x-ray emission histories in support of basic-science and inertial confinement fusion experiments at OMEGA"],"prefix":"10.1063","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7191-7252","authenticated-orcid":false,"given":"T.
