Final Remarks

Workshop program

Remarks

• Large synergies with other neutron detectors: MONSTER, DESCANT• Continuous feed back from gamma spectroscopy arrays: AGATA, GALILEO,

EXOGAM2, PARIS– Electronics coupling– Final geometry

• Importance of charged particle detectors, TRACE, DIAMANT• Physics need of neutron detectors

– Interest of the gamma spectroscopy groups (2n,3n)– Reaction + FARCOS (energy information, angular)

• Good understanding of the simulations– First test and comparison with simulations Very good agreement!– Unitary cell size and global geometry for NEDA

• Mechanics for NEDA (D. Jenkins will start discussion with J. Simpson, Daresbury)• Electronics: Synergies between different detectors: EXOGAM2, NEDA, PARIS,

DIAMANT

BC501A and BC537 detectors

Currently bought commercial detectors from Saint Gobain

•Two detectors 5”x5” BC537 (LNL-INFN)

•Two detectors 5”x5” BC501A (York-Valencia)

A. Pipidis (founded SP2PP) working on the characterization of the detectors.

Following steps

• Test of the prototype BC501A in Valencia/LNL/Warsaw/Uppsala

– Efficiency

– Cross talk

– …

• SIPM tests with neutron detectors – Synergies with PARIS (D. Jenkins)

• Decission before April/May 2011 on the FADC needed for NEDAM. Tripon

• Steering Committee decision on the final geometry for NEDA

• Steering Committee decision on the liquid scintilator to be used

• Steering Committee phases of NEDA

• Final MoU November 2011.

Phases of NEDA

The current development on new materials and readout systems for neutron detection makes necessary to build NEDA in four different phases:

• Phase 0: Upgrade of Neutron Wall with digital electronics.• Phase 1: R&D on new material and light readout systems for a

highly segmented neutron detector array.• Phase 3: Construction of a limited size Demonstrator • Phase 4: Final construction of NEDA

Budget issues

• Three main options:– 200 detectors BC501A – PM readout –Digital electronics

• Total cost: 600K€ (BC501A) + 200K€(Elec.) + 40K€ (mechanics) = 840 K€

– 200 detectors BC536 – PM readout – Digital electronics• Total cost: 2000K€ (BC537) + 200K€(Elec.) + 40K€ (mechanics) = 2240 K€

– Upgrade Neutron Wall - Phase 0 (Digital electronics)• Total cost (50 channels) = 40K€
