摘　　要：通过实验研究了有机膜对腔靶快离子的阻挡能力。研究结果表明，厚度在０．６μｍ以上的有机膜对腔靶快离于有很好的阻挡效果。这一结果对于在黑腔靶中建立一个高纯净的内爆Ｘ光辐射场具有重要意义。为满足快离子诊断的要求对法拉第筒结构作了改进。An experimental investigation on fast ions stopping by plastic foils has been made.The investigation shows that foils of a thickness over than 0.6μm can effectively stop fast ions.This result is essentially important for the foundation of a high pure X-ray radiation field in aindirectly driven laser fusion target.To satisfy the specific requirement of fast ions diagnostics,the feature of Faraday charge collector has been improved.
