The new, transportable PILOT (Phase-Imaging Located in One Transportable) - trap experiment aims to measure masses of short-lived nuclides with low production rates and half-lives down to 100 ms with relative uncertainties of about 10⁻⁸. This should be realised with a Penning-trap based modified buffer-gas cooling and PI-ICR technique [1]. In order to deal with the low production rates of some isotopes a modified dynamic buffer-gas cooling technique is used in only a single measurement trap. Therefore a fast piezo valve has been developed, which enables a fast and precisely timed helium injection into the Penning-trap, followed by a fast helium release to be directly able to measure in the same trap. This increases the overall efficiency by also avoiding the transport of ions between the traps. The setup is situated in the warm bore of a 6 T superconducting coldhead-cooled magnet which ensures transportability to different radioactive beam facilities. Here, mass measurements of e.g. rare superheavy nuclides become possible contributing to nuclear physics and the search for the island of stability, see e.g. [2]. The current status as well as the developed dynamic cooling method of this experiment are presented.
