Accelerator Consolidation Project
(comprises PS-CONS ,
SPS-CONS, LHC-CONS & LHC-SPARES)
Background: Consolidation has become necessary because of
the ageing equipment and the consequent need for general
maintenance and renovation.
The decision to use the PS and SPS machines as
injector for the LHC, in a programme which will last for more
than twenty years, means that a long term core consolidation programme for the LHC Injectors had to be launched. This was
started in the AB Department in 2003.
The following documents summarize the initial
consolidation activities in
December 2004 - First risk analysis report
& in
April 2005 - Second risk analysis report
This report
CERN-AB-Note-2008-002 summarizes the status
of the project in 2008, and this
document summarizes the risk score calculations.
In January 2010
the existing Consolidation activities (see above) and the were
combined with two new projects. These new projects cover the
consolidation of the LHC itself (LHC-CONS) and a program to build up a full stock of spare parts for the LHC
machine (LHC-SPARES). LHC-CONS covers the renovation of the
existing LEP infrastructure (Cooling, ventilation, electricity
supply), which was re-used for the LHC, as well as a number of
new items such as protection of LHC underground equipment
against radiation damage.
As a result, there are now 4 Consolidation
projects PS-CONS, SPS-CONS, LHC-CONS & LHC-SPARES, spanning 5
CERN departments (BE, EN, GS, SC and TE). The 25 year
Consolidation plan for the LHC Injectors has now been included
in the existing PS-CONS and SPS-CONS projects.
It should
also be noted that a number large consolidation activities (LHC
splice consolidation [TE], LHC R2E mitigation [EN]. PS Access
system consolidation [GS], SPS Access system [GS], SPS 18kV
distribution [EN] & the RAMSESII installation [DGS]) have been removed from the
tables shown below and the corresponding target figures. These activities are now
separate projects inside the CERN MTP, with their own
cost-to-completion.
******* Latest Update 23rd April 2012******
Here you can find the latest budget allocations
by
budget code for PS-CONS, SPS-CONS, LHC-CONS & LHC-SPARES for the
period 2012 to 2016. This includes the 2012 to 2013 carry
forward and a number of new urgent requests. The next update of
these allocations will take place in September 2012.
The negative material budget indexation of
2.7% for 2012 has been applied to these numbers.
The table shows the approved and funded Consolidation activities listed by project and
by department as well as the full list of all Consolidation
requests with all the associated budget profiles. This breakdown has been updated,
in November 2011, with the revised budget profiles and agreed by
all departments concerned.
****************************************
These workunits/activities have a status, which is
either:-
Completed = Finished and no longer requires
funding
Started = Approved, funded and work started,
with the given funding profile
Approved = Approved and funded, with the given
funding profile, but the activity has not yet started
Not Approved = Activity is not yet approved.
For all "not approved" activities there is also a priority, 1 -
highest, 5 = lowest, which is used to define which activities
will start and when etc.
The following reports outline a number of the
activities for the new LHC Consolidation
