The Amplitude Dependent Spin Tune and the Invariant Spin Field in High Energy Proton Accelerators
There is some ambiguity in the definitions and use of the concepts of spin tune and spin-orbit resonance on synchrobetatron orbits. We clarify these issues and provide a numerical illustration of the internal consistency of our definitions using the computer code SPRINT for HERA with a standard Siberian Snake arrangement. Furthermore, we demonstrate the calculation of the invariant spin field u...
متن کاملMeasurements of Tune Shifts with Amplitude at Lep
The beam orbit system of the LEP electron-positron collider is able to store the beam position over 1000 turns following a deflection by a horizontal kicker. A precise analysis of such 1000-turn data for many beam position monitors was used to study the dependence of the tune on the horizontal amplitude. The horizontal tune shift with amplitude was determined from the decay of the beam oscillat...
متن کاملName that percussive tune: Associative memory and amplitude envelope.
A series of experiments demonstrated novel effects of amplitude envelope on associative memory, with tones exhibiting naturally decaying amplitude envelopes (e.g., those made by two wine glasses clinking) better associated with target objects than amplitude-invariant tones. In Experiment 1 participants learned associations between household objects and 4-note tone sequences constructed of spect...
متن کاملAn Efficient Rank Based Approach for Closest String and Closest Substring
This paper aims to present a new genetic approach that uses rank distance for solving two known NP-hard problems, and to compare rank distance with other distance measures for strings. The two NP-hard problems we are trying to solve are closest string and closest substring. For each problem we build a genetic algorithm and we describe the genetic operations involved. Both genetic algorithms use...
متن کاملTime of Closest Approach in Three-Dimensional Airspace
In air traffic management, the aircraft separation requirement is defined by a minimum horizontal distance and a minimum vertical distance that the aircraft have to maintain. Since this requirement defines a cylinder around each aircraft rather than a sphere, the three-dimensional Euclidean distance does not provide an appropriate basis for the definition of time of closest approach. For instan...
