*THE COST OPTIMIZATION STUDIES OF THE SUPERCONDUCTING LINAC | |
|
||
| *High power superconducting linac develops fast recently with the strong demand from research and application. The cost and scale of the projects increase with the energy and beam power. For the superconducting linac, the choice of beta family is the key point to determine the effective acceleration efficiency of the whole facility. The Particle swarm optimization algorithm (PSO) is proposed to optimize the TTF value of the cavities to increase the acceleration efficiency. The project cost considering main hardware price is the final objective to evaluate the choice of beta family. The C-ADS lianc is used as an example to demonstrate the application of the new method. The optimization process and results are presented in the paper. | ||

*CONCEPTUAL DESIGN OF LEBT FOR C-ADS LINAC ACCELERATOR | |
|
||
| *In order to avoid the hybrid ions like H2+, H3+ injecting into the RFQ and the residual gas H2 tracing through the RFQ which may lead the RFQ cavity performance degradation, we present the conceptual design of the Low Energy Beam Transport (LEBT) for the China Accelerator Driven Sub-Critical reactor system (C-ADS) accelerator. The LEBT, consisting of one bending magnet and three solenoids and four short-drift sections, match the CW proton beam with 35KeV and 10mA to the entrance of a radio frequency quadrupole (RFQ). This bending LEBT can easily separate the unwanted ions. With the edge angles and one quadrupole to correct the beam asymmetry causing by the bending magnet, the simulation results meet the RFQ entrance requirements. | ||
