Cesium Oven for Hust Negative Ion Source : Design and Functional Tests

Zuo, Chen; Xue, Feng; Li, Jiawang; Li, Dong; Chen, Dezhi - 2022

Cesium will be evaporated inside HUST negative ion source to enhance the negative ion yield, by lowering the surface work function. In order to control the Cs vapour flux precisely, a temperature controlled Cs oven is developed. This paper introduces the design of the Cs oven body and...

Zhao, Hongwei; Li, Xuanfu; Feng, Yuzhao - In: Renewable Energy 16 (1999) 1, pp. 851-854

This paper presents a new approach to minimize the operation cost of wind-diesel system. Under the constraints of diesel units' startup/shut down time, ramp rate and power balance etc., the ‘Unit Commitment’ concept is introduced to construct the model for optimal operation planning of all...
