Dr Greg Hackman (TRIUMF)04/04/2008, 13:20Development of detectors and experimental methodsInvited PresentationThe Isotope Separator and Accelerator (ISAC) produces and extracts radioactive ion beams by the ISOL technique. These radioactive-ion beams are used at a variety of experimental stations for nuclear structure, nuclear astrophysics, or material science studies. Two large arrays of high energy-resolution HPGe detectors are sited at ISAC. Low-energy beams can be delievered to the 8pi...Go to contribution page

Dr Takehiko Saito (GSI)04/04/2008, 13:50Development of detectors and experimental methodsRecently, experiments to study hypernuclei by using induced reactions of stable heavy ion beams and rare isotope beams have been proposed at GSI by the HypHI collaboration. In the HypHI experiments, hypernuclei are formed by coalescence of hyperon(s) produced in the participant region of heavy ion collisions into projectile fragments, therefore, it is possible to produce neutron/proton rich...Go to contribution page

20. Development of a waveform readout system for Ge detectors in hypernuclear gamma-ray spectroscopyMr kenji hosomi (Department of Physics, Tohoku University)04/04/2008, 14:10Development of detectors and experimental methodsPresentationFor a hypernuclear gamma-ray spectroscopy experiment at the J-PARC K1.8 beam line, a new Ge detector array (Hyperball-J) is under construction. Hyperball-J consists of 32 Ge detectors that have a transistor-reset preamp. The reset-type preamp is necessary to withstand the high energy deposit rate in the experiment caused by penetrations of high energy beam particles. The maximum beam...Go to contribution page

Dr Eiji Ideguchi (CNS, University of Tokyo)04/04/2008, 15:15Development of detectors and experimental methodsPresentationWe have been developing a position sensitive germanium (Ge) detector array, CNS GRAPE (Gamma-Ray detector Array with Position and Energy sensitivity) for high-resolution in-beam gamma-ray spectroscopy using RI beams. In order to correct for the Doppler broadening effect from the fast moving reaction products, the array was designed to have position sensitivities in the Ge crystal by using the...Go to contribution page

Dr I-Yang Lee (Lawrence Berkeley National Laboratory)04/04/2008, 15:50Development of detectors and experimental methodsInvited PresentationGRETINA, the US gamma-ray tracking detector project, will use segmented Ge detectors to cover 1/4 of the 4-pi solid angle. It is scheduled to be completed in 2011. The current status, including the production and testing of segmented detectors, the use of digital electronics for data acquisition, results of signal decomposition and tracking, will be reported. A plan for GRETA, an array with...Go to contribution page

Prof. faisal Azaiez (IPN-Orsay)04/04/2008, 16:30Development of detectors and experimental methodsInvited PresentationFrom the experience gained in in-beam gamma spectroscopy using reactions at Intermediate energy and induced by rare isotopes, I will try to describe the various possibilities that will be offered in the future at RIKEN. I will present few experimental methods in which some future state of the art gamma detection instruments, such as AGATA, PARIS etc.., can be used to address important physics cases.Go to contribution page

Prof. Adam Maj (IFJ PAN)04/04/2008, 17:00The measurement of high energy gamma rays with high resolution has always been experimentally challenging, with the best resolution obtainable from a scintillator detector being around 10% from sodium iodide. The novel scintillator material LaBr3(Ce) promises a step-change in what is achievable using scintillator detectors with an unprecedentedly high resolution of <3%. The PARIS array [1] is...Go to contribution page
