Description
We are currently setting up a Penning-trap experiment to investigate
laser-ion interaction in high-intensity photon fields and study non-linear processes
like multi-photon and tunnel ionization of trapped ions. The setup
is designed to be transported to different high-intensity laser facilities, like
FLASH at DESY, or JETI/POLARIS in Jena. The trap is designed as an
open-endcap Penning trap, which allows free access from both sides for particle
loading and the laser beam. Beside the two endcap electrodes, it consists
of a split-ring electrode for excitation and detection in the center and two
conical-shaped capture electrodes for dynamic capture of ions from external
sources. A non-destructive detection technique of the ion motion, as well
as a selection of specific ion species of interest will be implemented. The
complete setup is located at the center of a superconducting magnet with a
field strength of up to 6 T. A pulse-tube cooler is used for cooling the trap
and the electronics to 4 K. Initially, a Ti:sapphire laser system with 10 mJ
pulse energy and a pulse duration of 30 fs will be used.
