5 Recent activity of CARE-HHH (2/2) oApril 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. oMay 2005: second meeting of the Pulsed Magnet Working Group with 19 participant ( 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-HHH-AMT workshop in Frascati (October 2005).

8 In Preparation Topics:  (i) optical designs and luminosity performance for alternative IR layouts (dipole first vs quadrupole first (Nb-Ti or Nb 3 Sn) vs ironless magnet at very low ß*,  (ii) beam-beam compensation schemes and machine-experiment interface),  (iii) machine and magnet parameters for high energy injectors: lattice, magnet aperture, injection and extraction for new ring in the ISR tunnel, super-SPS with new transfer lines, or booster ring in the LHC tunnel. CARE-HHH-APD Workshop LHC-LUMI-05 on "Scenarios for the LHC luminosity upgrade", Arcidosso, 31/08-3/09/2005. Web site:

9 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-map for a procurement and prototyping activity. CARE-HHH-AMT Workshop on Superconducting Pulsed Magnets for Accelerators (ECOMAG-05) in Frascati (Italy) during the week from 24 to 28 October, This workshop aims at giving a technological follow-up to the CARE-HHH- APD Workshop (LHC-LUMI-05, Arcidosso, August 2005).
