【摘要】 低温冷冻氘氚靶对于惯性约束聚变研究至关重要,主要有塑料微球靶、金属铍球靶、泡沫球壳靶等。根据微球球壳材质的不同,采用不同的低温冷冻氘氚靶制备技术。塑料微球靶采用"高压充氘氚-冷冻法"或"充气管充气法";金属铍球靶采用"低温、低压冷凝法"或"高温、高压扩散连接半球壳法";多孔泡沫球壳靶采用"球壳材料吸附氘氚液体法"。本文简述上述技术和方法的发展状况和趋势。更多还原

【Abstract】 The cryogenic deuterium-tritium targets are very important to laser inertial confinement fusion,and mainly adopt plastics capsule,Be shell,foam shell,etc.According to the performance of the shell material,several different techniques are taken to fabricate cryogenic deuterium-tritium targets.For plastics capsule,"high pressure fill deuterium-tritium,then freeze to low temperature" or "fill-tube fill deuterium-tritium" method is applied.For Be shell,"condensation deuterium-tritium at low-pressure,low temperature" or "diffuse-bonding two Be hemisphere shells at high temperature,high pressure" means is adopted.For foam shell,the way of "Absorbtion of deuterium-tritium liquid" is used.The development and the tendency of above technique and methods are summarized.更多还原
