Description
The GEO 600 gravitational wave detector uses advanced technologies
including signal recycling and monolithic fused-silica suspensions to
achieve a sensitivity close to the kilometre scale LIGO and VIRGO
detectors. As soon as the design sensitivity of GEO 600 is reached, the
detector will be operated as part of the worldwide network to acquire
data of scientific interest. The limited infrastructure at the GEO site
does not allow for a major upgrade of the detector. Hence the GEO
collaboration decided to improve the sensitivity of the GEO detector by
small sequential upgrades some of which will be tested in prototypes
first. The development, test and installation of these upgrades are
named 'The GEO-HF Project.' This paper describes the upgrades considered
in the GEO-HF project as well as their scientific reasons. We will
describe the changes in the GEO 600 infrastructure and the prototype
work that is planned to support these upgrades. Finally, we will point
to some laboratory research that identifies new technologies or optical
configurations that might undergo a transition into detector subsystems
within the GEO-HF project.
