Time-of-Flight wall design for HypHI project — •Christophe Rappold1, 2, Myroslav Kavatsyuk1, Olga Lepyoshkina1, Shizu Minami1, and Takehiko Saito1 for the HypHI collaboration — 1GSI, Darmstadt, Germany — 2ULP Strasbourg University
HypHI project at GSI, which was recently started, aims to study hypernuclei by means of stable heavy ion and RI beams induced reactions. Thanks to this production mechanism, hypernuclei are produced around at the projectile rapidity with a projectile fragmentation and a coalescence of a Λ-hyperon in the fragment, thus giving an opportunity to investigate hypernuclei at extreme isospins and to measure directly hypernuclear magnetic moments.
The project is divided in four phases, and the first one, phase 0, aims to demonstrate the feasibility of the hypernuclei spectroscopy with a stable 6Li projectile at 2 A GeV on a 12C target for Λ3H, Λ4H and Λ5He.
The spectrometer consists of the ALADIN dipole magnet, a diamond detector, three scintillating fiber detector arrays, two Time-of-Flight (TOF) walls, a K+ detector and three layers of drift chambers.
In this presentation, the design study and expected performance of TOF walls will be discussed.
