Description
Since the year 2002 intense efforts were devoted to the experimental
verification of
the proposed multiturn extraction based on beam capture inside
stable islands of
transverse phase space. Such an extraction is aimed at reducing the
losses of the
present Continuous Transfer used for the fixed target physics
programme at the SPS
and in particular for the high-intensity beam for the CNGS project.
Splitting of a
high-intensity, single-bunch proton beam was achieved without
detectable losses.
Furthermore, detailed measurements were performed to understand
better how to change
the beam parameters at the end of the capture process. In this
presentation the main
experimental results achieved in the year 2004 will be summarised.
The focus will be
on the outcome of the study for the implementation of the proposed
extraction
technique as a replacement of the present Continuous Transfer. The
new extraction
layout will be presented as well as cost estimate, schedule, and
possible scenarios
for the construction and commissioning.
