Members sReport from 11th INTC meeting 25/02/2002 (nToF part) 4. Report from nToF Technical Coordinator : P. Cennini - Shielding is being modified after the target, and after the sweeping magnet Work should be completed for nToF start-up (May, 10th) - "Proposal" for a Second Measurement Station at 165 m (SMS165) Third collimator needed (ø3=8 cm @ 152 m) [now ø1=11 cm at 136 m & ø2=1.8 cm @ 176 m] 5. Report on 2002 planned activities at nToF : P. Pavlopoulos - Beam requests for this year (7 1018p+ available) 1. Completion of nToF02 (Characteristics of the facility) 1 1018p+ 2. Experiment nToF03 3 1018p+ 3. P142 (submitted in september2001) 2 1018p+ 4. Pxxx to be submitted in May 1 1018p+ - Positive recommendations for 1 & 2 only - Spokesperson required by INTCfor each experiment - Second Measurement Station at 165 m (SMS165) not discussed DG statements in open session : - Members States support Isolde, nToF, (and AD) - nToF : Acknowledgement of progress in background studies Should produce data as soon as possible, and work "as Isolde"  

Additional Shielding at the exit of the Target Area Marble By adding shielding B & C, according with the FLUKA simulation, the expected reduction of the radioactivity induced by 7Be is ~ 7.

Shielding after the Sweeping Magnet (compatible with the construction of the Second Measuring Station)

Suggested lay out for the Second Measuring Station Proposal from Orsay
