Fourth order resonance of a high intensity linear accelerator

Fourth order and fourth sum connectivity indices of tetrathiafulvalene dendrimers

The m-order connectivity index (G) m of a graph G is     1 2 1 1 2 1 ... ... 1 ( ) i i im m v v v i i i m d d d  G where 1 2 1 ... i i im d d d  runs over all paths of length m in G and i d denotes the degree of vertex i v . Also,        1 2 1 1 2 1 ... ... 1 ( ) i i im m v v v i i i ms d d d X G is its m-sum connectivity index. A dendrimer is an artificially manufactured or synth...

New family of Two-Parameters Iterative Methods for Non-Linear Equations with Fourth-Order Convergence

A Collocation Method for Linear Fourth Order Boundary Value Problems

We propose and analyze a numerical method for solving fourth order differential equations modelling two point boundary value problems. The scheme is based on B-splines collocation. The error analysis is carried out and convergence rates are derived.

Status of a High Current Linear Accelerator at Csns

China Spallation Neutron Source (CSNS) consists of an H linac as an injector of a rapid cycling synchrotron of 1.6 GeV. The 324 MHz rf linac is designed with beam energy of 81 MeV and a peak current of 30 mA. The linac design and R&D are in progress. A test stand of a Penning ion source is under construction. RFQ technology has been developed in ADS study, with beam energy of 3.5 MeV, a peak cu...

Present Status of High-intensity Proton Accelerator Facility in Japan

The construction of the Project for High-intensity Proton Accelerator Facility(Figure 1). in Japan has been started this year. The Japan Hadron Facility of KEK1 and the Neutron Science Project of JAERI2 merged to this project. The purpose of this Joint Project is to pursue frontier science in particle physics, nuclear physics, materials science, life science and nuclear technology. Accelerators...
