本文叙述了一种比较新颖的整体式液体镓离子源的制备工艺及挂镓方法;测量了在不同温度下的电流-电压关系;以及在特定电压下,电流随时间的缓慢变化;对于针尖的几何形状,即顶点处的曲率半径对电流-电压关系的影响,用两种典型的针尖作了比较;试验还表明,这种源结构比较简单,容易实现和掌握,其寿命可达110小时以上. This article describes a relatively new monolithic liquid gallium source preparation and gallium gallium approach; measured at different temperatures, the current - voltage relationship; and at a specific voltage, the current with time slowly changes; for the tip The geometry, the radius of curvature at the apex, affects the current-voltage relationship using two typical tip types. Experiments also show that this source structure is relatively simple to implement and master, with a lifetime of up to 110 hours .
