Polyethylene naphthalate (PEN) and polyethylene teraphthalate (PET) are common plastics with uncommon scintillation properties. Here, we report the timing characteristics of PEN and PET, determined by exciting them with 120 GeV protons. The test beam was provided by Fermi National Accelerator Laboratory, and the scintillators were tested at the Fermilab Test Beam Facility. PEN and PET are found to have dominant decay constants of 34.91 ns and 6.78 ns, respectively.en: ScintillatorsScintillation and light emission processes (solid, gas and liquid scintillators)Scintillators and scintillating fibres and light guidesArticle10.3906/fiz-1912-92-s2.0-85096839989Q1433441WOS:000585330600002N/A
