扼要介绍了几年来在HI-13串列加速器上开展的辐照核孔膜的实验研究的一些结果,包括重离子种类的选择,能量和束流强度对核孔膜指标的影响以及提高辐照均匀性的措施等。实验用膜材为10～30μm厚PET(聚酯)薄膜,束流为3.5～4.5MeV/N的S束,核孔
Some results of experimental studies on irradiated nuclear pore membranes carried out over several years at HI-13 tandem accelerator are briefly introduced, including the choice of heavy ion species, the influence of energy and beam intensity on nuclear pore index, and the enhancement of uniform irradiation Sexual measures and so on. Experimental membrane material is 10 ~ 30μm thick PET (polyester) film, the beam is 3.5 ~ 4.5MeV / N S beam, nuclear pore
