AdvertisementThe ERINDA consortium groups 13 partners, equipped with nuclear data research infrastructures. The project sponsors the transnational access for experiments performed at any of the 13 facilities.The TANDEM accelerator of IFIN-HH is part of ERINDA.The last deadline for proposals: September 30, 2012www.erinda.org

Future project proposed for transnational access: CHANDA. NSDD Meeting, KFAS, Safat, Kuwait, January 27-31, 2013A. Negret et al. - RoSphere: The germanium array at the Tandem accelerator of IFIN-HH

ConclusionsThe 9 MV Tandem accelerator in Bucharest delivers a large variety of stable beams. The facility was completely modernized during the last years.

A large variety of detecting devices are available:The RoSphere array with up to 25 HPGe detectors and/or LaBr3 detectors,Clover detectors,A plunger device,Neutron detectors.

We are particularly well equipped for nuclear lifetime measurements.

Financial support is available for certain type of measurements.

Two PAC meetings /year; usually the requested beam time represents 150%-200% of the available beam time.
