Although a positive recommendation for the test was made at Chamonix 2003, it
is clear that its potential impact needs to be fully evaluated. In order to make
an informed decision we need to:
o Critically evaluate the arguments used to justify injecting beam into sector
8-7 of the LHC.
o Establish the required duration for the test and find the optimum time-slot
taking into account the availability of injectors and its potential impact on
the installation schedule.
o Elucidate requirements of, and the consequences for, the injector chains.
o Fully define the foreseen beam parameters and, in particular, estimate the
integrated beam intensity involved.
o Quantify the expected activation levels resulting from the test and potential
knock-on effects due to remnant radiation, e.g. access, traceability.
o Identify the consequences for installation and commissioning of other sectors
of the machine, before, during and after the test.
o Identify the consequences for installation and commissioning of LHCb before,
during and after the test.
o Evaluate the requirements, the cost of implementation and potential impact for
the access system and interlock system.
Having performed and presented the above approval can then be sought across the
project domains.
In the case of approval for the test being granted it would then be necessary
to:
o Fully define the studies to be performed, and draw up detailed planning for
the test itself.
o Fully define the required configuration for the sector.
o Fully define requirements of machine protection and interlock systems. Liaise
with those responsible to ensure that installation and test schedule will meet
requirements.
o Fully define requirements for controls, instrumentation, and beam-related
equipment. Liaise with those responsible to ensure that installation and
commissioning schedule will meet requirements.
o Fully define the access and interlock systems needed for the test. Liaise with
groups involved to ensure requirements established above are met. Define the
access conditions after the test.
o Define the radiation monitoring needed during and after the test. Establish
how to deal with any implications of remnant radiation (access, traceability).
o Liaise with hardware commissioning team and establish responsibilities during
overlap.
o Establish detailed consequences for installation and commissioning of other
sectors of the machine, before, during and after the test.
o Establish detailed consequences for installation and commissioning of LHCb
before, during and after the test.
o Establish a detailed planning from now to the test
o Ensure that the necessary formalities required by INB are in place
