11.34 Water on floor by AIDA NIM bins/forward AIDA stand/EURICA - it would appear
      that one or more cluster LN2 cryostat inlets have thawed are or thawing - failed fill
      and/or blocked manifold?

Julabo FL11006 water level and flow looks OK
      FEE temperatures OK - see attachment 4

Detector bias off
      FEE64 power off
      All AIDA power off

Source of water was determined to be wheeled air dehumdifier/cooler used to cool crates
      in 19" rack to right of AIDA (looking upstream). This had a small tray tank to collect
      water which was full to overflowing.

2x 60Co sources (#2530 and CD395) returned to cupboard B3F (between E12 & E17 stairwells)
