The use of nuclear emulsions in very large physics experiments is now possible thanks to the recent improvements in the industrial production of emulsions and to the development of fast automated microscopes. In this paper the hardware performances of the European Scanning System (ESS) are described. The ESS is a very fast automatic system developed for the mass scanning of the emulsions of the OPERA experiment, which requires microscopes with scanning speeds of about 20 cm^2/h in an emulsion volume of 44 micron thickness.

自动核乳胶读出系统自40年前提出以来,已经取得了显著的进展。超径迹选择器(HTS)是OPERA在大规模中微子实验中成功应用后研制的一种更快的读出系统。HTS拥有极宽视场物镜,扫描速度达到4700 cm $^2$ /h,比之前的系统快近100倍,因此有力地推动了许多新的实验项目。我们将在本文中描述的概念,规格,系统结构,和实现的性能。

质子治疗目前正在成为癌症治疗中广泛应用的临床实践,并且复杂的治疗计划系统通常用于最好地利用带电粒子的弹道特性。关于射束质量和质子范围的信息是优化治疗的关键问题。为此目的,质子射线照相术可用于质子治疗中,以获得关于质子范围、关于用于治疗计划优化的组织的平均密度的直接信息,并且以对患者的可忽略剂量执行成像。我们提出了一种创新的方法,基于核乳胶膜探测器的质子射线照相术,在该技术中,通过测量的位置和质子通过病人的身体的剩余范围来获得图像。核乳胶膜与组织等效吸收体之间的相互作用可以有效地用于高精度的质子径迹重建。基于核乳胶的探测器的第一个原型已经构思,建造和测试与治疗质子束在PSI。在伯尔尼的LHEP进行了乳剂的扫描,在那里为OPERA的中微子振荡实验开发了全自动显微镜扫描技术。轨道重建后,第一个有希望的实验结果已通过成像一个简单的幻影由PMMA制成的一个步骤为1厘米。还对第二个体模进行了成像,该体模含有5个5 x 5 mm^2截面的铝棒,位于不同距离处,并嵌入PMMA结构中。目前正在进行进一步的研究,以提高分辨率,并对更复杂的幻影成像。
