Präparation von Teilchenstrahlen für Experimente der Hadronenphysik:
langsame Extraktion an ELFE@DESY und ELSA, sowie Strahlkühlung an HERA
(Preparation of Particle Beams for Hadron Physics Experiments: Slow Extraction
at ELFE@DESY and ELSA, as well as Beam Cooling at HERA)
Abstract:
Various complementary experimental approaches are possible to study hadron
physics, all of which require
dedicated accelerator facilities. One approach,
known as the ELFE@DESY project, makes use of a continuous
electron beam with
an energy of 15 to 25 GeV, a current of at least 30 uA and very small emittance,
for fixed
target experiments. The formation of such a beam by stretching
a pulsed LINAC beam with the help of the HERA
electron ring has been studied.
At lower beam energies and currents this concept is already being used at
the
ELSA facility of Bonn University. Here the extraction process has been
studied intensively and has been compared
with measurements. Another approach
to study hadron physics is the use of an electron - ion collider. To achieve
high integrated luminosities cooling of the ion beam is necessary, especially
in the case of heavy ions. For
HERA high energy beam cooling with the help
of an electron storage ring has been studied.
