Amt activity osom

AMT activity OSOM

  • design of 2 T pulsed superferric magnet, follow-up of ECOMAG

  • cable and coil in the iron configured to minimize loss;

  • conceptual design that dissipates less than 10 W/m in the superconducting coil, and a warm iron (i.e. negligible loss power);

  • two variants: wide iron and compact version with correction coil, both suitable for a PS upgrade.

  • other options also examined, such as transmission-line magnets using large current (typically 100 kA), and open gap magnets; these options were discarded because of practical issues (bending radius, magnet size);

  • summary report within next few weeks [L. Bottura]

  • also ongoing: comparison of s.c. and n.c. options for fast cycling “PS2”

Amt exchanges

AMT exchanges

  • F. Broggi (Milano) visited CERN for 2 weeks in April to work on heat deposition in low-b region

    Primary goal: change of energy deposition versus distance  between triplet and IP. First study showed little dependence. Question byh US-LARP. Present activity: consolidate the conclusions and explore other parts of the parameter space; collaboration with C. Hoa/CERN on precise FLUKA description of IR1 and IR5, including exact magnetic fields (well advanced); set up a few PC's running the latest version of FLUKA (done); switch to latest FLUKA source (DPMJET), used at CERN; confirm the Valencia results with the latest descriptions, source and FLUKA version; prepare a study program of study showing parameter regions still to be explored;  investigate these (aperture, insertion length, crossing angle) [J.-P. Koutchouk]

  • E. Laface visited FNAL & BNL for 1 week to coordinate work on s.c. database
