Turning Device needs a crane to rotate the Stack
Support
Not possible in the test beam area !

28
HCAL Setup in test beam areaguess permanent
closed roof (except openings)

• installation of Movable Table and Stack with
  tricks only
• installation of AHCAL Layers in position B3
  critical
• 90 turning of the Stack not possible No cosmic
  test!

HCAL Setup in test beam areaguess roof opening
is big enough
30
HCAL Setup in test beam areaguess crane height
and crane load critical
needed hook height over roof 2.5 m
transport weight 12 tons
31
HCAL Setup in test beam areaguess one escape
route is not sufficient
Escape rote from B4
blocked

only top part will be fixed on HCAL Stack
37
HCAL Stack and ECALECAL is fixed do the first
absorber plate
ECAL outline
ECAL support
38
HCAL Stack and DHCALDHCAL must fit into the
Stack Support
Problem no DHCAL drawing available
DHCAL has VFE on both sides
existing gap between side plate and absorber
plate is not wide enough
