Abstract: | The China Spallation Neutron Source (CSNS) is a spallation neutron research facility being built at Dongguan in Guangdong Province. The 324 MHz Alvarez-type Drift Tube Linac will be used to accelerate the H− ion beam from 3 to 80.0 MeV with peak current 15 mA. The R&D of a prototype structure at the low energy section of DTL is taking place at IHEP. The first unit tank ∼2.8 m in length and 28 drift tubes containing electromagnetic quadrupoles are developed. The SAKAE coils are applied in the fabrication of the electromagnetic quadrupoles. This paper introduces the R&D status of the tank and 28 drift tubes. The fabrication process and measurement results of the electromagnetic quadrupoles of special interest are also presented. |
