Pt 5 is standard LEP tunnel R (3,8m dia)Access is from PM15 lift for pt 1, then throughout chicanes to reach each TANAccess is from PM56 lift at pt5 (dim 1200x800) then throughout chicane and bypass to reach the TANDimension of the materiel arriving in non shutdown is limited by chicanes and liftsAccess during shutdown: point 1 dismantling walls from inside, ie from pt2 ant pt8 (opening of shielded doors), point 5 from pt4 and 6, operning of shielded doors. Access open -> no big materials can accede TAN during run
