Description
The PlungeR INstrument at CEns (PRINCE) is a plunger device developed at CENS for lifetime measurements in picosecond range using the recoil-distance Doppler-shift (RDDS) technique. The system is based on a high-precision piezoelectric linear stage and incorporates interchangeable target and stopper assemblies, capacitance-based distance calibration, and active feedback control to maintain the target-to-stopper separation during in-beam measurements. Its compact geometry enables operation within the ASGARD $\gamma$-ray detector array and provides flexibility for future integration with ancillary particle-detection systems. The device was commissioned at the RAON facility by measuring the lifetime of the 4$^+$ state in $^{80}$Sr, populated through the $^{64}$Zn($^{20}$Ne, $\alpha$)$^{80}$Sr fusion-evaporation reaction.
This talk will present the commissioning results and discuss prospects for future developments and lifetime measurements at RAON.
