In this paper both the physical design and the engineering designs are presented. The China Spallation Neutron Source (CSNS) linac complex consists of an H- ion source, LEBT, a 3MeV RFQ, MEBT and a DTL linac, as shown in Fig. 1. Both the …

Dec 11, 2018 · The 324 MHz drift tube linac (DTL) is the main part of CSNS accelerator linac complex. It can provide 15 mA (30 mA in phase II) peak current beam with energy gain from 3 to 80 MeV [2] . It consists of four independent tanks with ∼ 9 m in length.

The China Spallation Neutron Source (CSNS) Drift tube linac (DTL) accelerates H- be am from 3 to 80MeV with 4 independent tanks. The 80MeV beam acceleration was achieved in January 2018. The linac is a key to the reliabil-ity of the whole CSNS facility since all the beams stop when these upstream facilities fail. Many efforts have been

Dec 1, 2023 · The CSNS DTL is a traditional Alvarez-type linac that accelerates H − particles from 3 to 80 MeV. The total length of the DTL is approximately 35 m, and the designed accelerating gradient is around 2.96 MV/m [ 3 ].

The CSNS linac accelerates H- to 80 MeV in the first phase, which consists of H- ion source, Low energy Beam Transport (LEBT), RFQ, Medium Energy Beam Transport (MEBT) and DTL, as shown in the Figure 1.

The construction of CSNS DTL is now in progress and several tests for cavity and drift tube are well performed. So far, the fabrication and measurement for 63 DTs of DTL tank1 are finished. In the meanwhile, tank machining has been finished and the copper plating on the tank inner surface is partially done. The DT assembly for

China Spallation Neutron Source (CSNS) mainly consists of an H- linac and a rapid cycling synchrotron of 1.6GeV[1]. The DTL linac are designed in two phases, with energy of 81MeV for phase I and 132MeV for phase II.

To achieve a higher current, we studied a scheme to replace the existing FFDD lattice in the DTL with an FD lattice. In the 1st tank of the DTL, the ratio between the bore radius and the RMS beam size is the smallest throughout the whole linac.

CSNS (China Spallation Neutron Source) is a proposed accelerator-based neutron source, operated by the Institute of High Energy Physics, to be built at Dongguan in Guangdong province – the first major scientific facility in south China. The facility is …
