Four Working Groups Meet:
---------------------------
SMTF WG1 on Cavities: Challenges in
making reproducible cavity performance
Location:Black Hole, WH
2NW
The main themes are : How do we achieve reproducibility at
35 MV/m Q=1010? What are
the known problems of the existing methods? What studies are underway and
are still needed to get better results? Whatt are the latest results on single and multi-cell
cavities?
Taking
into consideration the discussions at Snowmass and the high level of activity
detailed in the posters presented at SRF2005, we plan to continue these
discussions in the working group. Our goal is for the suggested leaders to
put together a document that outlines the best procedures that are followed, and how to avoid pitfalls.
We have
organized the Cavity discussions around 3 main topics. Our initial plan calls
for 4 plus hours for each topic. It may well turn out that each topic takes
longer than 4 hours, so our plan is to continue discuss each topic in the order
below, until it is exhausted, or to move among the first topics to accommodate
the time differences between US, Europe and Japan.
If we run out of time, and cannot cover all 3 topics, we
can try to continue these
discussions at a future collaboration meeting.
Speakers should talk about the
detail experiences, both positive and negative, as well as summarize what is
important to follow to get good, reproducible results, and what studies are
underway. Talks should avoid plans for future facilities.
We will
start with the first topic, EP, and continue as long as
needed

Technical
Board Agenda
Chair: Hasan Padamsee
Lunch Thursday..12:00 1:30
pm
Location: TBD.
Agenda
Topic 1: Will single and large
grain materials provide large cost reduction for example by eliminating the need
for ep or HT bake? How aggressively should the ILC community pursue cavity cost
reduction approaches such as hydro-forming/ spinning, Nb/Cu bonding, in order to
eliminate e-beam welding. How
aggressively should the superstructure
be pursued?(superconducting
joint)
Topic 2: Can a single crystal ingot be bought?
Does it make sense for the world cavity community purchase a
single crystal
ingot (roughly 4000 lbs = 50 cavities) to divide amongst three regions?
($1M)
Topic 3: How do we integrate this meeting with the upcoming TTC
meeting in Frascati in December?
