Ceiling Height Requirements
36 H157655_1_008
5.2 Minimum Ceiling Height
The minimum ceiling height requirements for operation of each magnet are listed in the
following table. Note that the values represent the absolute minimum, an extra 0.3-0.4 m
above minimum requirements will make all procedures safer and more convenient.
Note : The minimum ceiling height requirements for INSTALLATION may be greater than the
values in the table below, depending on the options selected.
Note : When calculating the minimum ceiling height, the height of the transport dewar plus
the long arm of the transfer line must be considered. Refer to the transport dewar supplier for
height specifications.
The following text explains how the ceiling height requirements in the ceiling height
requirements table were either calculated and/or their meaning. Note that the values were
calculated for the smallest available magnet stand.
Minimum Operational Ceiling
Height – Helium Transfer Line
29085
:
The minimum operational ceiling height using the
helium transfer line 29085 is calculated by adding the
height of the shim upper part that has to be inserted
into the cryostat, to the height of the top flange of the
cryostat.
Minimum Ceiling Height with
Helium Transfer Line 53962
:
The ceiling height using the standard helium transfer
line 53962 is calculated by adding the height of the
shim upper part that has to be inserted into the cryostat,
to the height of the top flange of the cryostat.
Minimum Ceiling Height for
Adapter WB -> SB: For all wide bore systems, the minimum ceiling height is
calculated to the top of the upper part reduction adapter
WB -> SB.
