Automatic scanning of nuclear emulsions with wide- angle acceptance for nuclear fragment detection

Nuclear emulsion, a tracking detector with sub-micron position resolution, has played a successful role in the field of particle physics and the analysis speed has been substantially improved by the development of automated scanning systems. This paper describes a newly developed automated scanning system and its application to the analysis of nuclear fragments emitted almost isotropically in n...

Developments in High-speed Track Design

Presently high-speed tracks are built on a large scale. Although ballasted tracks are still popular, more and more slab tracks are constructed. They have some significant advantages such as low maintenance, high availability, low structure height, and low weight. The main emphasis of this paper is on the application of non-ballasted concepts for high-speed operation. Special attention is given ...

Track geometry for high-speed railways

The present work consists of two main parts. The first part (Chapter 2 and 3) deals with a literature survey where a short introduction is given for track geometry and track/vehicle interaction. After the introduction, a survey over the present standard in Europe and Japan is made. In particular the recent proposals for a common European Standard (CEN) and TSI (Technical Specification for Inter...

Slab Track Design for High-speed

If the low-maintenance characteristics of slab track on open line are to be retained, great care must be taken to ensure that the subgrade layers are homogenous and capable of bearing the loads imposed [2]. The slabs can be precast or poured on site. The most known tracks with precast slabs are Shinkansen line in Japan and Max Bögl slab track designed in Germany [2], while as examples of the tr...
