Proton beam verification using RF power measurement data for a cw radiofrequency quadrupole linac

Abstract This paper presents an analysis of the Benchmark for Evaluation And Validation of Reactor Simulations (BEAVRS) performed using SCALE 6.1.2 and PARCS 3.2 computer codes. The benchmark specification contains a detailed design, operational data and measurements for a real 4-loop Westinghouse pressurized water reactor (PWR). The lattice physics simulations were prepared using TRITON depletion sequence and NEWT neutron transport solver (SCALE package). The 238-neutron group library based on evaluated nuclear data file – ENDF/B-VII nuclear data libraries was applied. A set of branch and burnup calculations was prepared, and group constants in the form of PMAXS files were generated with GenPMAXS. The full-core models were prepared using the PARCS nodal-diffusion core simulator. The PMAXS libraries were used with PARCS to investigate the core operation. The hot zero power measurement data, including control rod worths and critical boron concentrations, were compared using simulations, and satisfactory results were achieved. The first fuel cycle was simulated, and acceptable agreement with boron letdown curve and measurements were obtained. Finally, conclusions and recommendations for future research were presented.

And Performance

The need for power measurement transmitted by the running shaft has led to the need for using devices for measuring torque on the shaft. Of particular importance is the power measurement on high-speed machines, wherein some cases conventional measurement systems are either unsuitable or have low accuracy. Currently, data measuring systems are widely used in the researches of turbomachines. They allow to receive, process, transmit, store and display measurement data. Their application is relevant in relation to the priority of experimental study and subsequent modeling of characteristics and performance factors of expansion machines. The purpose of this research is a design and generation of the data measuring system for measuring torque on the running shaft of vortex expansion machines using a non-contact torsional dynamometer (strain-gauge clutch). The research has considered the results of the development of data measuring system, performed a theoretical analysis and presented the results of the practical application of the non-contact strain-gauge dynamometer designed for torque measurement on the shaft of low-power expansion machines when operating under bench test conditions. Has dealt with the problems of development, calibration. Keywords: data measuring system, torque, coupling, resistive-strain sensor, vortex expansion machine.

Activation Annealing

ABSTRACTCrystallization induced by proton beam irradiation using large area ion implantation at low temperature (less than 600°C) have been investigated. Phosphine gas containing hydrogen of more than 95% is discharged by RF power of 100W. Both phosphorus ions and protons are accelerated by a potential of 100kV and implanted into polycrystalline silicon (poly-Si) layers. At a range of beyond 2×1015 ions/cm2 P1 ions dose, amorphous phase is primarily formed and then changes into polycrystals again and its grain sizes grow up to 50nm in average diameter. The crystallization is found to occur simultaneously with phosphorus doping and to depend on the amount of the irradiated protons. This technique enables us to eliminate the activation annealing process for implanted dopant.
