Die Lichtlaufzeit (TOF) ist ein wichtiges Konzept in der Elektronenoptik. In Analysegeräten wird TOF verwendet, um verschiedene geladene Teilchen mit unterschiedlichen Impuls- oder Energiewerten oder unterschiedlichen Massen unter Verwendung der TOF-Differenz auszuwählen. In diesem Buch werden die Grundlagen des TOF-Energiespektrometers und vier Arten von Spektrometersystemen, die für unterschiedliche Anwendungsanforderungen geeignet sind, sowie die Methode der TOF-basierten Elektronenpaketmodulation erläutert. Es kann ein nützliches Nachschlagewerk für Wissenschaftler und Ingenieure im Bereich der Laser-Photoelektronenspektroskopie in der Atom- und Molekularoptik, der ultraschnellen Diagnostik unter Verwendung des Elektronenpaketmediums als Streakkamera und der ultraschnellen Elektronenbeugung sein.

Il tempo di volo (TOF) è un concetto importante nell'ottica elettronica. Negli analizzatori, il TOF viene utilizzato per selezionare diverse particelle cariche con valori diversi di quantità di moto o energia o masse diverse utilizzando la differenza TOF. Il libro elabora i fondamenti dello spettrometro di energia TOF e quattro tipi di sistemi spettrometrici adatti alle diverse esigenze applicative, nonché il metodo di modulazione dei pacchetti di elettroni basato sul TOF. Può essere un utile riferimento per gli scienziati e gli ingegneri che si occupano di spettroscopia laser di fotoelettroni in ottica atomica e molecolare, di diagnostica ultraveloce che utilizza il mezzo a pacchetti di elettroni come camera a striature e di diffrazione elettronica ultraveloce.

This monograph is devoted to developing a theory of combined measure and shift invariance of time scales with the related applications to shift functions and dynamic equations. The study of shift closeness of time scales is significant to investigate the shift functions such as the periodic functions, the almost periodic functions, the almost automorphic functions, and their generalizations with many relevant applications in dynamic equations on arbitrary time scales.First proposed by S. Hilger, the time scale theory-a unified view of continuous and discrete analysis-has been widely used to study various classes of dynamic equations and models in real-world applications. Measure theory based on time scales, in its turn, is of great power in analyzing functions on time scales or hybrid domains. As a new and exciting type of mathematics-and more comprehensive and versatile than the traditional theories of differential and difference equations-, the time scale theory can precisely depict the continuous-discrete hybrid processes and is an optimal way forward for accurate mathematical modeling in applied sciences such as physics, chemical technology, population dynamics, biotechnology, and economics and social sciences.Graduate students and researchers specializing in general dynamic equations on time scales can benefit from this work, fostering interest and further research in the field. It can also serve as reference material for undergraduates interested in dynamic equations on time scales. Prerequisites include familiarity with functional analysis, measure theory, and ordinary differential equations.
