Invited Presentation
The 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...

Development of detectors and experimental methods
Recently, 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...

Presentation
For 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...

We 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...

Invited Presentation
GRETINA, 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...

Invited Presentation
From 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.
