Ranko: No change in last few weeks for transport and installation.
Starting on Nov 18^th^ transport first D2, followed by Q1,Q2 Q3 on the
21^st^.

There had been discussion about installing the D1 and DFBX at a separate
time, but the final decision was to install them at the same time.
Therefore, we will be able to work on the interconnect of
d1-dfbx-q3-q2-q1 during our trip in January.

The start time for this January work continues to be January 9^th^ ..
therefore traval plans need to be made right away.. no later than Dec
1^st^ for the Fermilab crowd.

**Note: From 22 Nov 2005 email from Ranko, installation and interconnect
schedule has been delayed by at least two weeks**

Peter Limon told us about the sorts of training needed to have tunnel
access. There is a general safety course given in Building 55, offered
twice daily. You have to pass a (written?) test. This course covers
levels I-II-III. There is a level IV. That can be done on the web. It
can all be done in a day.

One needs PPE to work in the tunnel. Safety shoes (i.e. steel toe) are
not required; work boots would do. US Labs employees would be wise to
bring their own shoes. Helmets, airpacks, cell phones, will be taken
care of by our CERN-stationed collaborators. Peter will look into this.

There was a discussion about whether it was worth coming in early, say
on Friday the Jan 6^th^ in order to get this training. It was generally
felt that spending Monday doing training, with Tuesday in the tunnel
would match the CERN schedule.

We discussed "who should go and when"

Plan: send in two "waves" Rodger B. Bill Mumper and Tom Page go first.
Bossert/Mumper because they are the splice experts. Tom Page because he
is most knowledgeable about the interconnect kits.

Second wave will be Tom Nicol, Jim Rife and Mike Lamm. This group works
on the mechanical interconnect and Lamm looks over the electrical data.
The second group arrives on Jan 16 or Jan 17 so that there is an overlap
with group 1. Each group stays for \~2 weeks.

Joseph Rasson arrives with second wave, as does BNL participants
(probably John Escallier and Steve Plate or John Cozzolino). This
schedule is because we will start with the Q1 and work our way towards
the DFBX/D1 interconnect.

There was a discussion about the D1-DFBX interconnect. The splice
fixture for the Quads is being modified for use on the D1-DFBX. FNAL has
never tested it on the BNL cable although a similar fixture is used to
splice the KEK-Fermilab bus work.

The D1-DFBX instrumentation interconnect design is minimal. It follows
the letter of the CERN requirement. This design is similar to the RHIC
design. This has been knows for some time. Peter Limon volunteered to
look into this and make suggestions on how to improve it.

There was also a discussion about the thermal connection on the D1-DFBX.
There was a thermal bridge which was discovered during the April fitup
to be too long. Ranko says that this problem has been fixed.

Peter suggested that we should send CERN as set of leak test "clam
shells" . We use fixtures like this on the Fermilab test stand. The clam
shells are strapped over the bellows and sealed with Apiezion grease.
There was a discussion about how useful these would be at CERN. We
cannot spare the ones on our test stand and we don't have a set for
every interconnection. Still they are relatively easy to make and could
prove useful. Roger Rabehl volunteered to look into the cost and
schedule for getting a set for CERN.

There was a discussion about missing components. Peter gave examples of
components that cannot be found at CERN. I believe the US folk felt that
all components were accounted for.

Ranko will ask Ivo and Cedric to make a list of missing components and
send this list to Tom Page.

There was a discussion about the procedures. CERN is working at CERN to
embellish our procedures, integrate them with other CERN tasks and
translate them in French.

There is a "detail" with the HTS leads that needs to be put into the
procedures. There is a transport restraining screw that needs be
loosened prior to cooldown. Roger R. and Sandor will write a small
document to describe this.

We discussed the need to get all of the tooling at CERN PRIOR to
January. For example the soldering fixtures are still at Fermilab.
Rodger reported that the plan is to send a tested set of soldering
tooling by the end of November. A second set will be manufactured and
testing at Fermilab in December, and shift or hand carried to CERN in
early January.
