  1. Emulsion Development Activity C.Sirignano Opera CM - Mizunami - 20/01/2009

  2. CS facility status Activities: 1) Chemicals preparation on-site 2) Films labeling 3) 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

  3. LAB 1 development facility status Activities: 1) Chemicals preparation on-site 2) Films labeling 3) Development ( max 20 ECC / shift) 4) Films drying (24 h + 36 h) SeptemberJanuary • 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

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

  5. 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).

  6. Development statistics 812 bricks developed up to now

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

  8. 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.

  9. 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.
