Jet beams are widely used as targets in many fields of physics. Prominent examples are scattering experiments at hadron and lepton accelerators or at terawatt laser facilities, where pure and windowless targets with adjustable thickness are required in vacuum. Depending on the specific experimental situation, different types of targets such as gas-jets, cluster-jets or pellet streams can be...
Laser spectroscopy is a powerful tool to investigate the level structure and splittings in atoms and ions and to manipulate their inner and outer degrees of freedom. It is used at Storage rings since the late 1980s and has become increasingly popular. I will report on results of laser spectroscopy experiments performed since the last STORI conference at magnetic storage rings with a focus to...

The double electrostatic ion storage rings at the DESIREE facility [1] are unique and combine ultra-high vacuum and cryogenic temperatures of about 13K. This environment makes it possible to store ions on time scales ranging from microseconds...
The Rare-RI Ring (R3) is an isochronous storage ring for the purpose of deriving the masses of extremely short-lived rare RIs by applying TOF measurement method. Since the successful commissioning experiment in 2015, the technical developments have been continued to improve the efficiency and precision for mass measurements. Through initial experiments using unstable nuclei with well-known...
The spectroscopic observation of hadrons played a key role in the development of the quark model and the strong interaction. QCD predicts a zoo of "exotic" hadrons with more complex internal structures than the quark-antiquark mesons and three-quark baryons of the original quark model. Nowadays, there are experimentally observed states that are often assigned to the light meson or charmonium...
The Experimental Storage Ring (ESR) at GSI Darmstadt, Germany is the core instrument for unique physics experiments. It is operated for accumulation, storage, cooling and deceleration of a wide range of heavy ion beams in the energy range from 4-400 MeV/u coming from the synchrotron SIS18 via the FRagment Separator (FRS) or a direct transport line. Low energy decelerated beams can also be fast...
A unique storage ring optimized for mass measurements of rare radioactive isotopes, the Rare-RI Ring (R3), is operational at RIKEN [1]. A notable feature of R3 is its ability to measure nuclear masses with a high precision of 10$^{-6}$ in less than 1 ms. Since the first commissioning experiment in 2015, we have conducted several experiments with this ring. Through these experiments, we...
The Rare-RI Ring (R3) was constructed at the RIKEN RI beam factory for precise mass measurements of short-lived rare RIs with time-of-fight (TOF) method [1]. One of the requirements of the TOF detector is to minimize changes in ion velocity in the detector. We developed the TOF detector using thin foils dedicated for mass measurements at R3 (BE-MCP) [2]. In the BE-MCP, the secondary electrons...
