The post-doctoral fellow will participate in fully characterizing the GPIB and the electrostatic deflector, in terms of transverse and longitudinal emittances in the bunched-beam mode to fit the needs of the different experiments that will use the beams in the DESIR hall (favouring either time or energy dispersion at the expense of the other). It is also planned to increase the RF voltage of the GPIB to
optimize the transmission in bunched mode for very high charge (>105 ions/bunch).
The fellow will integrate the Exotic Nuclei group of LP2iB and will work in close collaboration with the members of the group involved in the PIPERADE project as well as the technical services. He or she will also be given the opportunity to participate in the experiments the group carries out on various facilities (JYFL, ISOLDE, RIKEN, GANIL ...) about mass measurements, exotic decays, nuclear structure or weak interaction studies with nuclear 𝛽 decay.
Candidates should have completed a PhD in nuclear physics, trap physics or a related subject since less than 5 years. They are expected to have a good knowledge in ion trapping and detection techniques, ion optics simulation tools (e.g. SIMION) as well as scientific programming (Python).
LP2iB is commissioning two traps that will be installed in the DESIR facility at GANIL. The General Purpose Ion Buncher (GPIB) is a radiofrequency quadrupole (linear Paul trap) that will cool and bunch all the beams delivered to DESIR. PIPERADE (PIèges de Penning pour les RAdionucléides à DESIR) is a double Penning-trap system that will act either as a mass separator to deliver large highly-pure ion samples to the setups of DESIR or as a mass spectrometer in its own right. A transfer line with an electrostatic deflector connects the two traps
