Modifications
Switched position of CB2 and one layer of
radiation shielding blocks
A small control office is built inside He
cooling room
Door position of He cooling room is
changed because CB1 and dewar is
located at the entrance hall of former one
Location and size of former sectional door
is changed to allow entrance of CB1 and

Ionized air ducts are reorganized regarding
radiation security
Before
• Former distribution was covering almost whole
area on the roof
• No trespassing was allowed
• Foam duct material, unsafe for radiation
• Glued to the ground, no maintenance without
damaging neighboring ducts
• Input and exhaust ports were at the same
elevation with beamline

controller for dampers, motors
and valves will be done
according to safety and hazard
analysis which is under the
scope of PSS contractor

Conclusions
• Infrastructure is the key point of an accelerator facility
• Without proper and reliable infrastructure actual progress can
not be met
• Late 2014 and majority of 2015 is spent on infrastructure
studies
• Complete missing parts
• Fix problems
• Infrastructure studies are almost completed.
• Technical specification documents are prepared for the rest, we
are waiting for the tender procedures to be completed
