    • An ion source (1500) has a removable anode assembly (1550) that is separable and from a base assembly (1552) to allow for ease of servicing the consumable components of the anode assembly (1500). Such consumables are easily removable and replaceable and may include a gas distributor (1510), a thermal control plate (1508), an anode (1512), and one or more thermal transfer sheets (1516, 1518, 1520) interposed between other components (1516, 1518, 1520). A pole piece (1514) and a cathode (1540) may also be part of the anode assembly (1550). The anode assembly (1550) may be attached to the base assembly (1552) via the pole piece (1514). The thermal control plate (1508) may have a port (1598) for passing working gas from one side of the thermal control plate (1508) to the other. An interface surface (1521) on the thermal control plate (1508) may have a pattern of recesses to allow the working gas to disperse underneath the gas distributor (1510). The gas distributor (1510) may be mounted to the thermal control plate (1508) in the anode assembly (1550) with several set screws (1542). The gas distributor (1510) may be disk shaped with counterbores (1548) in a surface to recess the nuts (1544) of the set screws (1542). Alternately, the gas distributor (1510) may be clamped or held in place by other structures or components of the ion source (1500). The thermal transfer sheets (1516, 1518, 1520) may be interposed between the consumable components within the anode assembly (1550). The thermal transfer sheets (1516, 1518, 1520) may be thermally conductive and either electrically insulating or conductive.
    • 离子源(1500)具有可拆卸的阳极组件(1550),该阳离子组件可从基座组件(1552)分离,以便于维修阳极组件(1500)的可消耗部件。 这种消耗品易于拆卸和更换,并且可以包括插入在其他部件之间的气体分配器(1510),热控制板(1508),阳极(1512)以及一个或多个热转印片材(1516,1518,1520) 1516,1518,1520)。 极片(1514)和阴极(1540)也可以是阳极组件(1550)的一部分。 阳极组件(1550)可以经由极片(1514)附接到基部组件(1552)。 热控制板(1508)可以具有用于将工作气体从热控制板(1508)的一侧传递到另一侧的端口(1598)。 热控制板(1508)上的界面表面(1521)可具有凹槽图案以允许工作气体在气体分配器(1510)下方分散。 气体分配器(1510)可以用几个固定螺钉(1542)安装到阳极组件(1550)中的热控制板(1508)。 气体分配器(1510)可以是盘形的,在表面上具有埋头孔(1548)以使定位螺钉(1542)的螺母(1544)凹入。 或者,气体分配器(1510)可以通过离子源(1500)的其他结构或部件夹紧或保持就位。 热转印片材(1516,1518,1520)可以插入阳极组件(1550)内的可消耗部件之间。 热转印片(1516,1518,1520)可以是导热的并且是电绝缘的或导电的。
