o
April 2005:

second meeting on LHC upgrade with ATLAS and CMS
physicists (8 participants).


Items discussed:



possible IR upgrade scenarios and implementation,


identification of a team to estimate high luminosity effects of
interaction debris on the superconducting triplets.


o
May 2005:

second meeting of the Pulsed Magnet Working Group with
19 participant

(
http://pmwg.web.cern.ch/PMWG/2nd%20meeting.htm
).


The main goals were:


define an inventory of resources (tooling and personnel) who may become
available.


review the present activity and identify possible synergies within
presently available resources.


discuss the organization of the CARE

In Preparation

Topics


summarise the requirements from particle physics, accelerator upgrades
and other fields (e.g. hadron therapy) to define a set of parameters for
the development of pulsed superconducting magnets for accelerators;


translate the above requirements in specifications for the performance
of strand, cable, magnet and auxiliaries (i.e. cryogenics, power supplies,
instrumentation, measurement systems);


define the R&D required to achieve the above specifications and
produce a tentative road
