CS facility status
Activities:
1) Chemicals preparation on-site2) Films labeling3) Development ( max 60 CSD /shift)4) Films drying (24 h + 24 h)
• Since September we are running with automatic temperature control on the developer tank.
• Brick development accomplished (2-5 / week)
• Wireless connection to BMM software running since December

SBAM
• Two “depiling” units installed • SW fixed for gridding and data storage (emulsion and lead thickness stored in
the DB.• Tests on-going on unit #1 using mechanical bricks to achieve robust and fast
cycle (< 30 min).

Emulsion films quality checks
• Regular tests on emulsion transparency, thickness, fog density and alphatracks density. Data shown in the last CM are confirmed no emulsion poisoninginside bricks, no lead surface radioactivity increase.

Conclusions & Planning
• 800 bricks and more than 1500 CSD handled and develop with no major faults
• We established a working protocol for training (development and quality checks) and the work is going smoothly day by day….
• Man power needed (expected 20 – 60 bricks/week from Feb up to Apr) agreed with Mario (1team leader + 2 shifters /week + LNGS experts + external operators) and call done.
