چکیده
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 current of 46 mA at 7% duty factor and a beam transmission rate more than 93%. The first segment of the DTL tank is under fabrication. A full-scale prototype of resonant high-voltage pulse power supply for klystron has been successfully demonstrated. This paper will introduce the design and R&D status of the linac.

Proton Accelerator Development in China
The China Spallation Neutron Source (CSNS) and the Chinese Accelerator Driven Systems (C-ADS) projects are both underway in China. The CSNS includes a 100 kW RCS accelerator and first beam on target is planned for 2017. The C-ADS project includes a high power superconducting linac with a low energy (25-50 MeV) initial stage by 2015 and higher power deployment later. In addition to these intense...

The measurements of electron Channeling Radiation (CR) have been performed at ELBE linear electron accelerator of the Forschungszentrum Dresden-Rossendorf. The aim of performing these experiments was to optimize radiation yield and spectral line width of CR in order to apply channeling radiation for preparing a monochromatic X-ray source. Diamond crystals can be used in relatively high electron...

Objective: Using Megavoltage photons generated by medical linear accelerator is a common modality for the treatment of malignant. The crucial problem for using photon beams >8MV is the photoneutron yields that increase the risk of secondary cancer that treated with high-energy photon beams. The contaminated neutrons produced in different components of the accelerator head and rely on many param...

متن کاملThe next Linear Collider Test Accelerator: Status and Results
At SLAC, we are pursuing the design of a Next Linear Collider (NLC) which would begin with a center-of-mass energy of 0.5 TeV, and would be upgradable to 1.0 TeV and beyond [1]. To achieve this high energy, for the past several years we have been working on the development of a high-gradient 11.4-GHz (X-band) linear accelerator for the main linac of the collider. In this paper, we present the s...
