Title:
Der Closed-Orbit der Elektronen-Stretcher-Anlage ELSA: Simulation, Messung
und Korrektur
(The Closed Orbit of the Electron Stretcher Accelerator ELSA: Simulation,
Measurement and Correction)
Abstract:
For the planned acceleration of polarized electrons the closed orbit correction
system of the Electron Stretcher Accelerator ELSA has been improved. Simulations
have been done to get a deeper understanding how the ELSA closed orbit behaves,
and how to improve the correction facilities. Work has been done on the ELSA
beam position monitors, and the development of a new narrow band signal
processing electronics has been started. Software for controlling the beam
position monitors and corrector magnets, as well as for calculating the corrector
magnet strengthes for the desired closed orbit correction, has been developed
to work under the new ELSA control system. Closed orbit measurements and
corrections have been performed to test the software, the hardware and the
simulation results. A beam position measurement method using the variation
of the focusing strength of a quadrupole has been tested.
