A new time-of-flight neutron spectrometer TOFED has been constructed for installation at Experimental Advanced Superconducting Tokamak. data acquisition system combining measurements of flight time and energy from the interaction neutrons with scintillators developed. The can provide a digitizing resolution better than 1.5% (to be compared >10% recoil particle in plastic scintillators) <1 ns. At same time, it is compatible high count rate event recording, which an essential...
To assess the neutron energy spectra and dose for different positions around Experimental Advanced Superconducting Tokamak (EAST) device, a Bonner Sphere Spectrometer (BSS) was developed at Peking University, with totally nine polyethylene spheres SP9 3He counter. The response functions of BSS were calculated by Monte Carlo codes MCNP GEANT4 dedicated models, good agreement found between these two codes. A feasibility study carried out simulated spectrum EAST, “experimental” result each...
A radiation shielding has been designed to reduce scattered neutrons and background gamma-rays for the new double-ring Time Of Flight Enhanced Diagnostics (TOFED). The was based on simulation with Monte Carlo code MCNP5. Dedicated model of EAST tokamak developed together emission neutron source profile spectrum; latter were simulated Nubeam GENESIS codes.

The novel neutron spectrometer TOFED (Time of Flight Enhanced Diagnostics), comprising 90 individual photomultiplier tubes coupled with 85 plastic scintillation detectors through light guides, has been constructed and installed at Experimental Advanced Superconducting Tokamak. A dedicated magnetic shielding system for TOFED, is designed to guarantee the normal operation in stray field leaking from tokamak device. measurements numerical simulations carried out employing finite element method...
It remains an important challenge to quantitatively describe the corrosion of reinforced concrete (RC) structures under chloride penetration. When considering uncertainties encountered throughout life cycle RC exposed a corrosive environment and evaluating their safety reliability, complexity problem intensifies. To address these issues, this paper focuses on time-dependent reliability analysis corroded beams, utilizing phase-type (PH) fitting method. Initially, model for beams is...
The 2.5 MeV TOFED (Time-Of-Flight Enhanced Diagnostics) neutron spectrometer with a double-ring structure has been installed at Experimental Advanced Superconducting Tokamak (EAST) to perform advanced emission spectroscopy diagnosis of deuterium plasmas. This work describes the response function spectrometer, which is evaluated for fully assembled instrument in its final layout. Results from Monte Carlo simulations and dedicated experiments pulsed light sources are presented used determine...
The 2.5 MeV neutron spectrometer TOFED (Time-Of-Flight Enhanced Diagnostics) has been constructed to perform advanced emission spectroscopy diagnosis of deuterium plasmas on EAST. instrument a double-ring structure which, in combination with pulse shape digitization, allows for dual kinematic selection the time-of-flight/recoil proton energy (tof/Ep) space, thus improving capability resolve fast ion signatures spectrum, principle up factor ≈100. identification and separation features from...
This article describes a novel aperture-coupled feed, for the excitation of cavity-backed quad-slot antenna with circular polarization. Firstly, linear polarization (LP) is proposed. Then, which composed cross-shaped coupling aperture and T-shaped feeding microstrip line, will be applied to this LP antenna. By differing lengths four radiation slots together 90° phase difference equal magnitude between radiations from two pairs can generated. As result, good performance axial ratio achieved...
This paper introduces a new harmonic-suppressed bandpass filter (BPF) using quarter guided-wavelength stepped-impedance resonator (SIR) based on the low temperature co-fired ceramic (LTCC) technology. The voltage-null point of third harmonic is found miniaturized SIR (by choosing reasonable ratios impedance and electric length). It can be chosen as exciting location feed line in BPF design so that resultant cannot excited suppressed successfully, while passband operating at fundamental...
