摘要

我所600kV高压倍加器需要一台流强达毫安级的高频离子源。提高高频源的流强，必须设法提高气体放电产生的等离子体密度和改善引出结构。Countant

[1]

曾以增大高频功率达700W，气耗量75ml/h，得到7mA离子源。Eunbank

[2]

用增大气耗量达114ml/h，功率300W，得到15mA的流强。然而功率和气耗量太大，都不适于加速器长期连续运行。

Abstract

In order to meet the needs of 600kV cockroft-walton accelerator

a radiofrequency ion source using 15MC/s and 300 watts osicillator has been constructed with transverse magnetic field.

Two constructions of this source is discribed and the operational characteristics are given.

An ion beam current of 5mA at 5kV extraction voltage has been obtained with gas flow of less than 25cc/h and operating life of more than 100 hours. At accelerating voltage of 400kV

the beam current at the target which is about 4m from the outlet of the source is 2.2mA.
