Experimental results showed that timely cutting of the plant was an effective way to obtain new cuttings for cultivation and accelerate growth. New cuttings 0.05 kg in weight are suggested to be used as " seeds" and the old plant should be harvested. At present, artificial cultivation with a type of underwater raft applicable in places where there is strong wind will expand cultivation to more regions in Hainan Province.展开更多

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.展开更多

The axial accelerating field is ramped from 2.2 MV/m to 3.1 MV/m in this tank. The required field flatness is less than±2% with the standard deviation of 1% for the beam dynamics; the field stability should be less than 1% for machine stable operation. After successful alignment, RF tuning was carried out focusing on the field profile measurement. Four slug tuners and eleven post couplers were applied in this procedure. The ramped field and required stability had been achieved by fine adjustment of the slug tuners and post couplers. In this paper, the preliminary tuning results are presented and discussed.展开更多
