Artigo IPEN-doc 30387 Thermal neutron dose measurements using TLD-100 detectors in the IPEN/MB-01 reactor core2024 - CAVALIERI, TASSIO A.; SIQUEIRA, PAULO de T.D.; SHORTO, JULIAN M.B.; YORIYAZ, HELIOConsiderable experimental effort has been aimed at uncovering a reliable way to perform a dosimetric assessment in mixed radiation fields. In fields composed by gammas and neutrons, TLD dosimeters are usually applied to execute such measurements, although there is no consensus on the most favorable strategy to employ them. In this context, TLD-100 measurements within two different core configurations of the IPEN/MB-01 research reactor and Monte Carlo simulations have been used to investigate the behavior of those detectors in multiple mixed radiation fields, deriving a methodology to evaluate the dose deposition in the dosimeter by different gamma and neutron energy spectra and intensities. A surprising outcome is the linear neutron dose response shown by TLD-100 even irradiated by so distinct irradiation fields.Artigo IPEN-doc 25902 A proposal to study long-lived isotopes produced by thermal neutron irradiation of digital devices2019 - ZAHN, G.S.; GENEZINI, F.A.; MORALLES, M.; SIQUEIRA, P.T.D.; MEDINA, N.H.; AGUIAR, V.A.P.; MACCHIONE, E.L.A.; ADDED, N.; SILVEIRA, M.A.G. daIn this work, we present a facility to study errors in digital devices exposed to thermal neutrons from a beam hole in the IEA-R1 nuclear reactor, as well as the long-lived isotopes produced in the irradiation of digital electronic devices under a slow neutron field. Preliminary results obtained with the analysis of a 28nm SRAM-based Xilinx Zynq-7000 FPGA are presented.Artigo IPEN-doc 21130 Boron film thickness determination to develop a low cost neutron using Monte Carlo Method2015 - COSTA, PRISCILA; RAELE, MARCUS P.; YORIYAZ, HELIO; SIQUEIRA, PAULO de T.D.; ZAHN, GUILHERME S.; GENEZINI, FREDERICO A.Artigo IPEN-doc 19357 Differences TLD 600 and TLD 700 glow curves derived from distict mixed gamma/neutron field irradiations2013 - CAVALIERI, TASSIO A.; CASTRO, VINICIUS A.; SIQUEIRA, PAULO T.D.Artigo IPEN-doc 17141 MCNP study the BFsub(3) detection efficiency2011 - CASTRO, VINICIUS A.; CAVALIERI, TASSIO A.; SIQUEIRA, PAULO T.D.; FEDORENKO, GIULIANA G.; COELHO, PAULO R.P.; MADI FILHO, TUFIC
