  3. The Super-FRS and its Branches EXL ELISE ILIMA R3B NuSTAR- [Nuclear Structure Astrophysics and Reactions] Collaboration

  4. R3B for kinematically complete measurement of reaction with high energy Exotic Nuclei Neuland GSI, SINP, Fz T.Aumann et al. FAIR (Facility for Antiproton and Ion Research )

  5. Appearance of low-lying strength in neutron-rich nuclei 130,132Sn, P. Adrich et al., PRL 95 , 132501 Klimkiewicz et al, PRC 66, 2007 Threshold strength: r V() T. Nakamura et al., PLB 331, 296 (1994) U.Datta Pramanik et al., PLB553, 63 (2003) T. Nakamura, A.M.Vinod et al., PRL 96 (2006) 252502.

  6. Total statistics obtained for Pb target (0.98g/cm2): 34Al 1.7x10^6 , 31Mg 5x10^6 32Mg 3.5x10^6 27Ne 2.5x10^6 1.Sigle particle strength 2.Pigmy resonance 3. Resonance states Expt. at GSI, 2009, Sept., 2010

  7. Plan to Use of MMRPC as active part of neutron detector • >Resistive plate chamber (MRPC) • +Converter >Cheaper than scintillator+PMT • Already very good time resolution achieved for fast minimum ionizing particle (A. Schutauff NIM 533(2004)65) NIMA314, 136 Datta Pramanik, Prog. Part and Nucl 59 (2007)183-192 A.Leistenschneider et al., PRL 86 (2001) 5542 Design goals: • Detection of a relativistic neutrons in a TOF spectrometer (t<100ps) • Measurement of four momentum vector (dx,dy,dz~1 cm) • Reconstruction of projectile energy with E=30 KeV at 1 MeV • Recognization of multihit neutrons K.Boretzky, U.Datta Pramanik et al, 2005, R3B collaboration

  8. Development of MRPC at SINP, Kolkata: XI plan project (DAE) Funds for prototype from DAE (2007-2012) 0.7 M Euro The planning, designing, fabricating of various parts and building of the detector at SINP, Kolkata (2009) Gas: R134, Isobutene, and SF6 . MMRPC detector is 20 cm X 40 cm: 2, 4, 6 gaps gglass were used with very thin coating conducting layer to build cathode : both national (vergo), international products: Anode plate was made by PCB with 2 cm strip. Local workshop at Kolkata

  9. GAS mixing unit, A. Joshi, RPC2007 Gases used: R134A(88%), SF6(5%), Isobutene (7%) Block diagram of gas mixing system

  10. Various stages of detector building at SINP Conductive layer on glass Full assemble Anode structure

  11. Testing at laboratory using • Gamma source (60Co) • Cosmic background Coincidence set-up of MMRPC and scintillator detectors Presented at International conference on RPC detectors, U.Datta Pramanik et al RPC2010, 10th Feb, Darmstadt

  12. R&D for this detector at India 1. Development of detector: SINP, Kolkata 2. Gas recycling: Alpha Pneumatics+IIT Kharagpur+SINP 3. Electronics: SINP+University of Burdwan+CU+GU 4. Simulation and mechanical structure: Calicut University+ Viswa Bharati University+SINP More institute may join: IIT Roorkee, Aligarh Muslim University, DU, PU, IIIT Madras etc. Money matrix: Cost matrix: RPC based: Scintillators: 2.5 Meuro 3.2 Meuro We ask : 18 Crores Rs. 10 Crores in FAIR ( 1.4 MEuro) 8 Crores : Infrastructure+man power+travel+ R&D etc. at India

  13. Future Plan: • The detector resolution (150-200)ps in offline test • We shall do online test using electron, proton, neutron beam • 2. Build large area detectors (50cm x 1 m), (50cmx2m) • and testing with proton, electron an neutron beam • 3. Exploring Gas recycling (open loop), gas analyzing • Exploring Readout system of RPC • 4. Exploring scintillator as an active part of Neutron detector • with different types readouts • 5. Comparison study with scintillator and MRPC (developed by • different laboratories in NEULAND collaboration) • and expt at GSI (Deuteron beam in 2011) for final selection • Of prototype. • 6. Ask for Fund to build 1/2 of Neuland at India (FAIR-India)
