First measurements of the Collins and Sivers asymmetries of charged hadrons produced in deep-inelastic scattering of muons on a transversely polarized 6LiD target are presented. The data were taken in 2002 with the COMPASS spectrometer using the muon beam of the CERN SPS at 160 GeV/c. The Collins asymmetry turns out to be compatible with zero, as does the(More)
Future experiments on hypernuclei γ-spectroscopy at FINUDA@DAFNE and PANDA@FAIR require the operation of germanium detectors in high magnetic fields (B ≈ 1 T). The performance of these detectors in such an environment has not been well investigated. In particular, one might expect three problems to arise: (i) breakdown of FETs in the preamplifiers, (ii)(More)
The HypHI project aims to study hypernuclei by means of collisions of stable heavy ion and rare-isotope beams on stable target materials [1, 2]. As the first step (Phase 0), the feasibility of precise hypernuclear spectroscopy with heavy ion beams will be demonstrated with 6 Li beam at 2 A GeV impinged on a 12 C target by identifying 3 Λ H, 4 Λ H and 5 Λ He(More)

The main idea of the HypHI project is to perform precise hypernuclear spectroscopy with stable and unstable heavy ion beam at GSI and FAIR[1]. The HypHI collaboration plans the first experiment Phase 0 in 2009 to investigate the feasibility of hypernuclear spectroscopy with heavy ion beams. In the Phase 0 experiment, three sets of Scintillating Fiber(More)
Multi-fragment decays of and U targets at energies between E/A = 400 MeV and 1000 MeV have been studied with the ALADIN forward-spectrometer at SIS. By adding an array of 84 Si-CsI(Tl) telescopes the solid-angle coverage of the setup was extended to θ lab = 16 •. This permitted the complete detection of fragments from the projectile-spectator source. The(More)
