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

September January

• 5 lines working 5 lines working

• No temperature control Temperature control HW & SW installed on 6 lines, final configuration under test on line 1

• No humidity control in drying rooms Humidity control working since October.

• Line #6 to be completed Line # 6 under preparation

• Rolling carpet to be completed Rolling carpet to be completed

SBAM

The “opening” unit is installed and working (10 min /brick full cycle).

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.

Chemicals

Available @ LNGS

• Developer & Starter - 2000 bricks

• Acetic Acid – 2500 bricks

• Fixer – 2500 bricks

• Glycerin & Driwell – 2500 bricks

NEEDED for 2009 RUN (5000 bricks)

• Developer & Driwell - 2000 bricks ready at FUJI firm, order needed by the end of January in order to get the material @ LNGS in May.

• Quote under preparation for Chemicals available in Europe.

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.
