For a few years, the medical cyclotron Proteus C-235 at the Cyclotron Centre Bronowice in Kraków, Poland has been regularly used fornuclear structure experiments. One of the ongoing studies is focused on the γ decay of collective states populated in (p,p'γ) reactions. In a recent experiment, γ decays of excited states in the energy region of the Pygmy Dipole Statesin 208Pb have been observed. Good efficiency and energy resolution provided by the PARIS clusters and LaBr3Ce scintillators facilitate a comparison of the obtained energy spectra with previous measurements of pygmy states in this nucleus.

A very first experiment in the field of nuclear structure at the Cyclotron Centre Bronowice (CCB) facility in Kraków, Poland has been performed recently. The medical cyclotron IBA Proteus C-235 located at CCB produces proton beams in the energy range of 70-230 MeV, that can be used for experimental purposes as well. In the reported measurement, the energy of scattered protons at the incident beam energy of 85 MeV and emitted γrays from the excited 208Pb target were measured in coincidence. During the experiment excitations in the energy region of the Giant Quadrupole and Dipole Resonances, as well as the Pygmy Dipole States were observed. By applying different conditions on the data, spectra corresponding to decays of excited states to selected low-lying levels in 208Pb were obtained, allowing a look into the Brink-Axel hypothesis.

A new accelerator facility -- Cyclotron Centre Bronowice (CCB) -- was opened two years ago in Kraków, Poland. Aside from cancer therapy, a scientific program of the nuclear structure research making use of proton beams in the energy range of 70-230 MeV plays a significant role as well. Lead and graphite targets were used to prove the feasibility of exclusive experiments on collective modes in various nuclei. The experimental technique consists of simultaneous energy measurement of scattered beam particles in coincidence with γ rays emitted from excited nuclei. This article describes the set-up and the method of analysis used for the experiment. [ABSTRACT FROM AUTHOR]

KATANA -- the Kraków Array for Triggering with Amplitude discrimiNAtion, has been built and used as a trigger and Veto detector for the SπRIT TPC at RIKEN. Its construction allows for operation in magnetic field and provides a fast response for ionizing particles giving the approximate forward multiplicity and charge information. Depending on this information, trigger and veto signals are generated. The Multi-Pixel Photon Counters were used as light sensors for plastic scintillators. Performance of the detector is presented.
