Green and Red channels were repaired by crimping and securing the grounding of the cables and fixing the cables securely to the table.
All problems during the repair process were visible on the scope. See example attatched.

|
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. |
