SEQUOIA/ARCS Instrument Development Team Meeting
Pasadena, March 20, 2005
Room 142 Keck Laboratory, Caltech Campus
This Instrument Development Team (IDT)
meeting was attended by scientists interested in the ARCS
and SEQUOIA instrument projects.
The purposes of the meeting were to inform the
attendees of the
status of these projects, and seek their opinions on issues
that could affect the operations and science performed with
these two instruments.
Specific concerns were:
1) Any usage of high magnetic fields at samples in
ARCS or SEQUOIA needs to be coordinated with the high
sensitivity of the spin-echo instrument to fringing
fields. It appears that it is not possible to shield standard
15 T magnets adequately to ensure fields of 50 mG at neighboring
instruments.
2) Single crystal experiments on ARCS and SEQUOIA require
more experience with both sample manipulation hardware and
with data reduction software.
