A scaning with 252Cf along the Z-axis of the neutron detector is carried out. The setup is similar to the scaning carried out in October 2016.

Observations:

- Clovers are put inside the detector without voltage.

- AIDA detector is out of the moderator.

- Position in Z is given with respect to the moderator side opposite to AIDA.

- The shielding for in-beam neutrons is mounted. It corresponds to HDPE 2.5cm + 1mm Cd + 20cm HDPE. The distance moderator to shieldind is 34.6mm

- There are two additional neutron sources in the Hall, aprox 10m from the detector. One 241AmBe (30mC) and 244Cm/O13 (500mC). Both sources produce an increase of the neutron background up to approx1n/s (x10 higher).

- Datafiles are located in the dac computer, path:
