Description
The electron accelerator facility ELSA houses two external high-energy beam lines. These deliver primary electron beams with energies between 0.8 and 3.2 GeV, extracted via slow resonant extraction from a synchrotron to a total of three different experimental sites. One beam line hosts two hadron physics experiments, while the second, located on the opposite side of the synchrotron, is used for detector tests and medical physics experiments.
Recently a new operation mode has been developed to serve both external beam lines with an extracted electron beam simultaneously. This enables running detector test experiments at low rates (tens of kHz) alongside high-rate hadron-physics experiments at GHz extraction rates, significantly increasing beam time availability.
We present properties and underlying beam dynamics of this operation mode, with particular emphasis on advanced methods for rate control at the second beam line.
