詹特切克生平简介

 威利鲍德·詹特切克(WillibaldJentschke),是位于汉堡附近的德国粒子物理实验室DESY的创立者,欧洲核研究组织(CERN)的前负责人,他过完90岁生日之后,于2002年3月11日逝世。詹特切克1911年生于维也纳,24岁获得核物理学博士学位,他在维也纳一直工作到1951年,然后他到了伊利诺斯州的恩巴拉大学,任回旋加速器实验室的负责人。1955年,当汉堡大学让詹特切克负责实验物理学研究时,他申请基金在德国建立现代的核物理研究设施。     

Numerical Calculation and Analysis of Track Etching Process

Heavy ion irradiated polymers can be chemically etched to form track membrane with pores in the micro and sub-micro ranges. It has been reported that pore growth during etching can be related to track structures. A latent track has a track core inside and a track halo surrounding the track core. By single track etching it is observed that etching in the track core is much faster than in the track halo where the etching rate is even lower tlian that of bulk material. For multi-track etching, no such stages can be seen by the conductance measurements.     

双预脉冲驱动X射线激光实验研究

 在“星光-Ⅱ”激光装置上进行了双预脉冲驱动类氖铬X射线激光实验，介绍了实验方法和实验结果，并对结果进行了简短讨论。由于目前“星光”装置输出能量较低，所进行的双预脉冲驱动未能显著提高X射线激光强度，改变预脉冲幅度时X射线激光强度也未有显著变化。利用MED103程序进行了模拟计算，其结果与实验结果一致。     

Emittance Measurements for Beams Extracted from LECR3 Ion Source

High quality ion beams are required by IMP cyclotron and atomic physics research, so it is important to research and measure beam emitt ance of ECR ion source. Intense beams extracted from ECR ion source usually have low energy, so it is suitable to use Electric-Sweep Scanner to measure the emittance. This kind of measurement is popularly used at ECR ion source, and it has some prominent merits such as high accuracy, very short time of data processing and easy expressing of the emittance pattern. So we designed and built this emittance scanner to measure emittance of the ion beams produced by LECR3 ion source. The structure of the ESS is shown in Fig.l, and the photo of the ESS is shown in Fig.2.
