The Isoscalar Giant Monopole Resonance (ISGMR) and the Dipole (ISGDR) compression modes have been studied in doubly-magic unstable nucleus 56Ni. They were measured by inelastic α-particle scattering inverse kinematics at 50 MeV/u with MAYA active target GANIL facility. centroid of ISGMR has obtained Ex=19.1±0.5MeV. Evidence for low-lying part ISGDR found Ex=17.4±0.7MeV. strength distribution dipole mode shows similarity prediction from Hartree–Fock (HF) based random-phase approximation (RPA)...
The inelastic ?-scattering experiment on 56Ni in inverse kinematics was performed at an incident energy of 50 MeV/u GANIL. A very high multiplicity for ?-particle emission observed with our phase-space limited experimental set-up. maximum multiplicity, which cannot be explained by means the statistical decay model, amounted to seven. ideal classical gas model kT = 3 MeV fairly well reproduced momentum distribution and alpha particles. This result strongly suggests that alpha-gas state may...
We present the first results obtained from S3 Low-Energy Branch, gas cell setup at SPIRAL2-GANIL, which will be installed behind spectrometer for atomic and nuclear spectroscopy studies of exotic nuclei. The installation is currently being commissioned offline, with aim to establish optimum conditions operation radio frequency quadrupole ion guides, mass separation bunching, providing high-efficiency low-energy spatial spread isotopes interest. Transmission mass-resolving power measurements...
We report on the construction of an UHV compatible 40 mm active diameter detector based micro channel plates and assembled directly feed-throughs a DN63CF flange. It is charge division technique uses standard 2 inch Si wafer as collector. The front end electronic placed air side flange allowing excellent immunity to noise very good timing signal with reduced ringing. important aberrations are corrected empirically providing absolute positioning accuracy 500 μm while 150 resolution measured in center.
New facilities like FAIR at GSI or SPIRAL2 GANIL, will provide radioactive ion beams low energies (less than 10 MeV/n). Such have generally a large emittance, which requires the use of beam tracking detectors to reconstruct exact trajectories nuclei. To avoid angular and energy straggling that classical would generate in due their thickness, we propose SED (Secondary Electron Detectors). It consists pressure gaseous detector placed outside coupled an emissive foil beam. Since 2008, different...
The focal plane of S3 (Super Separator Spectrometer), a new experimental area SPIRAL2 at GANIL, will be used for identification nuclei, and requires the reconstruction their trajectories velocities by Time Of Flight (TOF) method. Classical tracking detectors in-beam would generate lot angular energy straggling due to thickness. One solution is use SED (Secondary Electron Detection), which consists thin emissive foil in beam coupled low pressure gaseous detector out beam, detection secondary...
Active targets, such as the ACtive TARget and Time Projection Chamber (ACTAR TPC) being developed at GANIL, are detection systems that operate on basis of a time projection chamber but where filling gas also serves thick target for nuclear reactions. In physics experiments, energy resolution is primary importance to identify reaction products precisely reconstruct level schemes nuclei. These measurements based deposited pixelated pad plane. A MICROMEGAS detector used in ACTAR TPC ionization...
Abstract SPIRAL1 at GANIL is a facility dedicated to the production of radioactive ion beams (RIBs) and their post-acceleration. A major upgrade allowed this produce RIBs condensable elements. It does so by using both hot 1+ source an ECR Charge Breeder where latter used increase charge state for The team pursuing R&D on fronts in order expand offer RIBs. Several sources have been or will be tested 2023: (1) MonoNaKe, surface source, being modified ionize short-lived lithium isotopes (2)...
The $^{18}\mathrm{Ne}(d,t)^{17}\mathrm{Ne}$ and $^{18}\mathrm{Ne}(d,^{3}\mathrm{He})^{17}\mathrm{F}$ single-nucleon pickup reactions were measured at 16.5 MeV/nucleon in inverse kinematics together with elastic inelastic scattering channels. full set of exclusive differential cross sections was compared the mirror reaction channels on stable $^{18}\mathrm{O}$ after consistent reanalysis using coupled calculations. Within this interpretation scheme, most spectroscopic factors extracted for...
Abstract The SPIRAL1 charge breeder is now under operation. Radioactive beam has already been delivered [1] to physicists for performing experiments. Although breeding efficiencies demonstrated high performances stable ion beams, regarding radioactive beams were found be lower than expected in the first experiment. optics, prior injection of 1+ ions into breeder, prime importance [2] reaching such efficiencies. Moreover, intensities are so low that it very difficult tune breeder. tuning...
Abstract The behaviour of the Forced Electron Beam Induced Arc Discharge (FEBIAD) ion source used at GANIL within Target Ion Source System (TISS) “Système de Production d’Ions Radioactifs Accélérés en Ligne” (SPIRAL1) has been recently investigated to improve its performances and render them reproducible. Off line systematic studies evolution working parameters (cathode shape, cathode heating, anode current) with time temperature configuration have clearly shown origin issues was mainly...
Abstract The charge breeder of the SPIRAL1 (SP1CB) facility provided this year to physicists new Radioactive Ion Beams (RIB) for experiments and machine development, showing significantly improved performances compared those obtained during initial on-line commissioning SPIRAL 1 upgraded [1]. These were thanks thorough studies conducted off-line with 1+ ion beams produced by FEBIAD ECR sources, successfully demonstrating ability couple SP1CB them. In particular, established its capability...
The TULIP project ( https://anr.fr/Projet-ANR-18-CE31-0023 ) aims to produce radioactive ion beams of short-lived neutron-deficient isotopes using fusion-evaporation nuclear reactions in an Isotope Separator On Line (ISOL) system. A Ni target was chosen Rb and Sn isotopes, bombarded, respectively, by Ne Cr primary at energies close the Coulomb barrier. Owing Target Ion Source System (TISS) configuration, operational TISS temperature had be 1300°C. Several tests were performed determine a...
