High pressure ionization chamber is widely used to detect various radiation fields due to its good energy response. A new Multi-layer planar high pressure ionization chamber is designed suitable for measuring directional radiation field of high dose rate, because of its high electric field strength. In this paper, MCNP program is used to simulate and calculate the energy response of this ionization chamber to obtain the energy response of high energy photons, which could not be obtained by experimental methods. The results show that this ionization chamber can measure photon radiation energy up to 10MeV.

China ADS study program was Supported by the "Strategic Priority Research Program " of the Chinese Academy of Sciences at 2011, which aims to design and build an ADS demonstration facility with the capability of more than 1000 MW thermal power in about twenty years. The driver Linac is defined to be1.5 GeV in energy, 10mA in current and in CW operation mode. To meet the extremely high reliability and availability of ADS, the Linac is designed with much installed margin and fault tolerance. ADS accelerator is composed of two parallel 10MeV injectors and a main Linac. The superconducting acceleration structures are employed except the RFQs. This paper will present design of the China ADS accelerator and related key technology developments.

The China Spallation Neutron Source (CSNS) accelerator is designed to accelerate proton beam pulses to 1.6 GeV at 25 Hz repetition rate, striking a solid metal target to produce spallation neutrons. The accelerator provides a beam power of 100 kW on the target in the first phase and then 500 kW in the second phase by increasing the average beam intensity 5 times while raising the linac output energy. The project construction has been formally launched in 2011 and it is planed to complete the project in March 2018. It is one of the high intensity proton accelerator projects in the world and it imposes a great challenge to Chinese accelerator community. This presentation will cover the status and challenges of the CSNS project.
