There were no comments on the minutes of the previous meeting.
Jan made a presentation of the systems in the MPS and their interfaces. The
presentation is only a starting point and more technical details will need to
be provided for the main systems. For the ‘other systems’, as mentioned on
slide 1, the accent for commissioning regarding the machine protection system
will mainly concern the actual checking of the transfer / reception of the interlock
signal. For all systems it will be important to determine the test conditions.
Comments made during the presentation are included in the slides.
It was proposed that every body
will make a list of the functionality and the interfaces for ‘their’ system. Verena
and Jorg will do this for the Injection System. Laurette and Bruno will make a
presentation on the commissioning of the MPS functionality of the vacuum system
in the next meeting. This can serve as an example for the other systems.
The mandate was agreed upon.
A possible format to be used for
the test procedures and the test results can be the edms
/ MTF system as used for the LHC hardware commissioning. Rüdiger, with Jörg and Verena, will check with the hardware commissioning
team and will invite an ‘expert’ to present their way of documenting and will
propose a possible solution for the commissioning of the MPS.
Bruno presented a summary of the many
systems connected to the ring Beam Interlock System, including the timing
system, Safe Beam Flag, the Injection BIS, timing for the Post Mortem, LSA (for
the sequencer and Inject and Dump mode). The interfaces to the LBDS and the
Injection system are special as they are ‘bi-directional’. In total almost 200
hardware systems need to be connected to the BIC. The Commissioning of the BIS is
composed of several phases, of which the first stage starts in the week of 18
December (Hardware Commissioning = stand alone tests), passes via tests during
the cold check-out (all user systems connected) and finishes with tests with
beam.
Solutions need to be found what to
do when some of the systems are not ready on time. This should be discussed in
a future meeting.
Ben presented three slides giving some more details on
the electrical architecture of the BIS. Systems can be tested in a safe way
because there are separate A and B channels which can
be controlled. For the Software Interlocks, a special interface is required. The
last slide shows the special interface towards a system which needs to be
triggered, like for a Post Mortem event or an event for another BIC, like the Injection
BIC. The presented schematics form the basis for the more detailed test
procedures.
