Contamination types:• MLI• Soot• (Debris)

Contamination distribution:Soot


History: Cleaning methods after 3-4 incident (1)

2 August 2013

Foam plugs for the soot: Use of two plugs for horizontal and vertical parts of the beam screen Use of alcohol-wetted and dry foam plugs Up to 50 passages in each direction with wet foam plug and up to 15

passages with dry plug

Example of C19R3.V2

Vacuum, Surfaces & Coatings GroupTechnology Department C. Garion 52 August 2013

History: Cleaning methods after 3-4 incident (2)

Air flux for the MLI: 1st step: automatic pumping/venting

A cycle : 20 s pumping, 18 s plateau, 2 second vent The pressure is reduced from 1 atm to 0.8 atm in 2 s (to be compared to the arc pump down of 200 mbar/h) Apply this process for 30 min (40 pumping/venting cycles)

2nd step: aspiration with local pertubation controlled by endoscope nozzle blows filtered air, the MLI residues left behind the beam screen and the

RF fingers are directed towards the beam aperture where they are aspired away. Time : 5 min per PIM, speed of 3 m/min along the beam screen

Vacuum, Surfaces & Coatings GroupTechnology Department C. Garion 62 August 2013

History: cleanness after 3-4 incident

Acceptance criteria:After discussion with AB-ABP and following Chamonix it was agreed with the management that :- 1 fibre per half-cell - 2 debris (MLI or other less than 1 mm2) per magnet can be left in the beam tube after the cleaning process !

Schedule of inspection and cleaning activities in 3-4

2 August 2013

All interconnections and beam vacuum lines related to these activities in sector 3-4 are opened including the QBBI.A14R3 and QBBI.A20R3

VSC activities in parallel with SIT reconnection work. No closure of the beam vacuum lines (PIM installation before the end of the activity)

Start of VSC activities beginning of August (8 August)• ~ 3 weeks in total• From point 4 first (to avoid interaction with optical fibre activity, t.b.c.);• Mid august from point 3


Conclusion

2 August 2013

A scenario of inspection and cleaning of the cold vacuum beam lines in sector 3-4 is proposed.

The additional work for the SMACC team has been minimized while providing a maximum of informations and efficiency of the cleaning.

A cleaning of the 2 beam vacuum lines will be carried out based on pulsed air flow.

Procedure and tooling have already been applied in 2009.
