A prototype of a new beam profile monitor with tracking and TOF capabilities for degraded beams at HISPEC/DESPEC at FAIR has been built at the Institute of Nuclear Physics at the University of Cologne [1]. The device constists of two detectors in series, each with an active area of 80x100mm. The working principle is based on secondary electrons being created by the ions passing through a thin s...

page 156 Abstract: Already proven in a wide array of industrial applications, surface acoustic wave devices (SAWs) also have been demonstrated to hold substantial potential in the biosensor arena. Currently, SAW resonators coated with a biolayer can distinguish specific biomolecules in both liquid and vapor phases. By incorporating periodic perturbations in the design of SAW delay line, we were...

PREFACE The work described in this thesis was carried out under the supervision of Dr P. The work is my own except where otherwise stated and was not done in collaboration with others. It is the not the same as any other dissertation submitted for a degree, diploma or any other qualification at any university. This thesis does not exceed 60 000 words. ORIGINALITY Chapter 1 is a review of develo...

The measurement principle of the transit time difference method of the ultrasonic flowmeter is presented. The hardware structure and realization method are introduced. The software function and work mode are overviewed. In order to enhancing flowmeter's precision and stability a Xilinx CoolRunner CPLD and a Texas Instruments microcontroller from MSP430 family are applied in high precision timin...

A miniaturized arrangement based on magnetostrictive delay line (MDL) mechanism, able to be used as sensor, is realized using thin films technology. In order to obtain high-performance miniaturized magnetostrictive delay line arrangement we used Fe, Ni and Fe70B20Si6C4 amorphous thin films as magnetostrictive sensing element because of their better magnetic and magnetoelastic characteristics th...

In this work classical and modern control theory methods are applied for rigorous mathematical analysis and design of different computer architecture circuits such as clock generators, synchronization systems and others. The present work is devoted to the questions of analysis and synthesis of feedback systems, in which there are controllable delay lines. In the work it is mathematically strict...

The new telecommunication networks scenario is characterised by a very rapid increase of the volume of traffic, and also very variable and unpredictable traffic demands. In this context, all-optical packet switching is emerging as the most promising technology for covering such new requirements. In this paper, we deal with the performance analysis of an optical packet switch with a feedback del...

Also, the power-handling capacity of a transmission line is maximum when it is "flat", i.e., operating at low SWR. Lastly, it is important to be able to interconnect a number of different components into a system, and the only way that can be done reliably and predictably is by constraining the reflection coefficients of the various interfaces through impedance matching. Multiple reflections ca...

The role of linear transversal filters in signal processing is discussed in Section I. Linear filters for signal processing must often have complicated impulse responses, with large bandwidth and large time­ bandwidth product. The lineae transversal filter, a delay line with weighted and summed taps, is ideally suited for the implementation of such filters because of its simplicity of gynthesis...

The role of optical buffering in the development of all-optical cross-connects is discussed, followed by an analysis of fibre delay line implementations in optical buffers. It is shown that the traffic model plays an important part in the analyses of the systems, together with the traffic load, the use of internal buffer wavelengths, and the cross-connect architecture. Travelling buffers have s...
