  1. Additional Associates Elena Wildner for WP4 EUROnu Annual Meeting

  2. New Associates I • Small Group from Physikalisches Institut B, Rheinisch-Westfaelische Technische Hochschule in Aachen • Achim Stahl • Students • Work Focus • Realization of beta beam in the Hera Tunnel (Desy) • Physics studies • Added Value • New Site Option • More flexibility for a realization of a beta beam (“green field”?) 26/3 2009 2 EUROnu Annual Meeting EUROnu Annual Meeting Courtesy Achim Stahl

  3. Physics Driven Choice of Site Possible realization with one detector only (price): nm-beam: SPL: <En> = 260 MeV Lopt = 134 km CERN – Frejus: 130 km ne-beam: g = 150 Lopt = 300 km g = 500 Lopt = 1000 km CERN – Frejus: 130 km DESY – Frejus: 960 km 3-Flavor Oscillation needs two significantly different baselines to disentangle CP and matter effects 26/3 2009 3 EUROnu Annual Meeting EUROnu Annual Meeting Courtesy Achim Stahl

  4. Conceptual Layout New ring in the HERA tunnel for final acceleration and as decay ring 12 T Dipole 35 m long HERA rebuilt as RCL with RF replacing experimental inserts in straight sections Source & pre-accel. „Halle West“ 4.7 GeV preacceleration (new) 12 T Dipole 2 x 35 m long Ion source (new) 26/3 2009 4 EUROnu Annual Meeting EUROnu Annual Meeting Courtesy Achim Stahl

  5. New Associates II • Weizmann Institue of Science, Revohot • Michael Hass • Partners: GANIL and Soreq • Collaboration with Aachen (exchange of students) • Work Focus • produce light radioactive isotopes also for beta beams • secondary neutrons from an intense, 40 MeV d beam (6He and 8Li) and direct production with 3He or 4He beams (18Ne). • Use of superconducting LINACs such as SARAF at Soreq (Israel) and the driver for SPIRAL-II (GANIL). • Added Value • To produce strong beta beam ion candidates or production methods not in EUROnu Courtesy Micha Hass 26/3 2009 5 EUROnu Annual Meeting EUROnu Annual Meeting
