LOHENGRIN is a recoil mass spectrometer for studying the properties of the exotic isotopes produced during the fission process. It allows us to study mass, kinetic energy and charge distribution for products from thermal neutron induced nuclear fission at very high resolution.

The beam-intensity at the separator allows also detection of γ-rays, conversion electrons, β-rays and delayed neutrons, and coincidences between these particles.

Investigation of spectroscopic properties of exotic neutron-rich nuclei

• spins and parities
• magnetic moment and life-time measurements of exited nuclear states
• conversion electron spectroscopy

Fission process investigation and industrial applications

• fission fragments’'mass, kinetic energy and nuclear charge distributions for different fissile systems from binary and ternary fission reactions
• delayed neutrons from fission fragments
• diffusion coefficients for actinids in different surrounding material

The instrument combines an horizontal magnetic deflection followed by a vertical electrostatic deflection. The focusing magnet, the Reverse Energy Dispersion (RED) dipole magnet, increases up to a factor of seven the particle density at the focal position.
