Determination of luminosity for in-ring reactions:A new approach for the low-energy domain
Luminosity is a measure of the colliding frequency between beam and target
and it is a crucial parameter for the measurement of absolute values, such as
reaction cross sections. In this paper, we make use of experimental data from
the ESR storage ring to demonstrate that the luminosity can be precisely
determined by modelling the measured Rutherford scattering distribution. The
obtained results are in good agreement with an independent measurement based on
the x-ray normalization method. Our new method provides an alternative way to
precisely measure the luminosity in low-energy stored-beam configurations. This
can be of great value in particular in dedicated low-energy storage rings where
established methods are difficult or impossible to apply.Comment: 8 pages, 5 figure
