Description

An electron energy measurement based on resonant spin
depolarization has been running permanently at BESSY II
for several years. This high-precision energy measurement
was set up primarily for users of synchrotron radiation for me-
teorological applications from the Physikalisch-Technische
Bundesanstalt (PTB). Recent investigations have led to a
better understanding of the method and the possibility of
shortening the measurement time. This allows for new obser-
vations and the use of the energy measurement for different
applications such as the model-free measurement of the
natural chromaticity, the momentum compaction factor or
synchrotron sidebands.
