Comment: 
- 252Cf source placed at the center using cardboard piece, z=0cm, orientation of the source with its axis parallel to the beam axis, i.e. axis of the source upstream to the beam. 
- 3He counters with a threshold 5% lower compared to previous measurement.
- Clovers inside the moderator, surface position 11.6/2 cm from the each one. 
- AIDA not inside the moderator.
- Without in beam PE shielding.
