1 Cross section measurements at LNL M.Mezzetto (INFN-Pd) on behalf of INFN-LNL: M. Cinausero, G. De Angelis,G. Prete

2 The INFN Legnaro Laboratory The INFN Legnaro Laboratory 3 Elettrostatic Accelerators - Tandem XTU (16 MV) - Van der Graff (7 MV) - An 2000 (2 MV) 1 Linac - Alpi SC 1 RFQ injector - Piave SC Experimental Halls - About 10 Detection systems 1 RIB Facility planned - SPES (ISOL)

3 A new approach for  -beam Beam cooling with ionization losses – C. Rubbia, A Ferrari, Y. Kadi and V. Vlachoudis in NIM A 568 (2006) 475–487 “Many other applications in a number of different fields may also take profit of intense beams of radioactive ions.” 7 Li(d,p) 8 Li 6 Li( 3 He,n) 8 B 7 Li 6 Li See also: Development of FFAG accelerators and their applications for intense secondary particle production, Y. Mori, NIM A562(2006)591 Cross section and Angular distribution measurements 20-30 MeV

6 Experiments at Laboratori Nazionali di Legnaro TANDEM-LINAC accelerator complex Inverse kinematic reaction 7Li beam at 10-30 MeV Target: deuterated plastic 7Li + d  8Li + p Protons detected with 8  LP:  E-E hodoscope Si+CsI(Tl) Detection Energy range: 2° to 24° : 1-64 AMeV 34° to 177°: 1-34 AMeV,

7 Experiments at Laboratori Nazionali di Legnaro 7Li Ball: 30 cm inner diameter 126  E-E telescopes (collimated + 1°) 300  m Si - 5 mm CsI(Tl) angular range 34° to 177° 7 rings, 18 telescopes per ring. 126 energy spectra 7 angles (per run)

8 Experiments at Laboratori Nazionali di Legnaro 7Li First Experiment performed in July 2008 Inverse kinematic reaction: 7 Li + Cd 2 target E=25 MeV Data reduction in progress Problems (technical): Background reactions on the C Matrix Proton spectra contaminated Absolute Normalization needed Problem (political): Shortening in humane resources due to Italian government cut of INFN positions

9 Possible future improvements: a) Better REACTION IDENTIFICATION detecting HEAVY FRAGMENTS in coincidence with p Detector developments - TOF measurements of Li ions Electromagnetic separation (MAGNEX spectrometer, available at LNS) b) More CLEAN TARGET Duterons adsorbed into heavy matrix (Pt, no reaction on matrix) Gas jet target (not available at LNL) Cryogenic target (not available at LNL) What next Analyze data and evaluate contamination problems EU support for a research fellowship
