4. Report from nToF Technical Coordinator : P. Cennini

- Shielding is being modified after the target, and after the sweeping magnetWork 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"
