SAMPLE OF PROFESSIONAL ACHIEVEMENTS

2007 - 2013: FCM - A superconducting Fast Cycled Magnet
Design construction and test of an energy-efficient fast cycled super-ferric magnet for applications in the injector chain of accelerator complexes. The project started as a part of the overall consolidation and upgrade plan of the LHC injector complex, as an alternative to the normal-conducting electromagnet design of the PS upgrade (PS2). The magnet design is based on the use of a low-loss Nb-Ti internally cooled cable (concept borrowed from the JINR Nuclotron), wound in a vacuum impregnated coil. The coil location in the iron yoke is optimized to reduce the peak field and the nuclear radiation load. A short model was built and tested, achieving bore field of 2 T (vs. 1.8 T operating specification) at peak ramp-up rate of 2 T/s, for repetitive sequences of several thousands of cycles, and AC loss below 2 W/m (vs. 5 W/m target).
1999 - 2008: FiDeL - The Field Description for the LHC
A parametric model for the field and field errors in normal- and superconducting magnets for accelerator applications, presently the most complex and complete field forecast system implemented in a superconducting accelerator. The work covered the complete development, from the inception, through the conceptual design, validation, formal specification and commissioning of the system in the LHC Software Architecture (LSA) system that controls the LHC accelerator. The activity required approximately ten years of magnetic measurements, a dedicated instrumentation R&D, the systematic analysis of a significant amount of stored data (4.5 millions of coil rotations, for 50 GB of magnetic field data), scientific work in a new domain (3 Ph.D's and a few Masters Theses were granted on the subject), two years of data pruning and modeling leading a team of about ten professionals, collaborations and participation to runs in Tevatron and RHIC, and the final commissioning in the LHC.
2002 - 2007: Magnet sorting in the LHC, Magnet Evaluation Board (MEB) activities
Magnet acceptance for installation and optimal sorting based on considerations of hardware (magnet types), magnet conformity (mainly interconnect or instrumentation issues), geometry (optimization of the mechanical aperture), field quality (optimization of beam quality parameters and minimization of the required correction in operation). As Chairman of MEB, leading a team of some fifteen physicists and engineers (beam physicists, magnet experts, magnet coordinators), defined the working procedures, monitored progress through regular meetings, and resolved interface and priority issues throughout the five years of intense activities. The result is the installation of the over 1900 LHC magnets in a sequence that fully conform to the specified performance. In addition, mechanical aperture was optimized with an estimate gain of 1.5 mm with respect to a random installation (a few exceptions have been timely identified and optics adapted), the required corrector strength was minimized (e.g. below 30 % of the installed capability for the orbit correctors), beta-beating was contained (all known effects are within the allocated 14 % budget), and known instabilities sources were reduced (e.g. sorting has reduced the third resonance driving term by more than a factor 2). Beam measurements at the LHC have confirmed the above expectations.
2005 - 2007: Conceptual design and realisation of a novel integrator for magnetic measurments (FDI)
Following an analysis of performance requirements of magnetic measurement instrumentation at CERN for the coming years, initiated the design of a precision numerical integrator that replaces the presnt market standard. The new design is based on a fast ADC (18 bit SAR converter) to digitize the amplified input voltage, an FPGA (Spartan XC3S1000L) that performs all logic and I/O operation, and a DSP (Shark 21262) that performs numerical integration on the basis of a precision clock (50 ns). Prototype realised in collaboration with colleagues at CERN and in Italian Universities (Napoli, Benevento, two Ph.D.'s granted on this subject). The new integrator is presently licensed from CERN to Metrolab (Geneva, CH) for commercial use and distribution.
1995 - 2007: Series Test of the LHC Magnets
As responsible of the team in charge of field measurements (15 to 20 scientists and technicians), led the the field mapping of the LHC magnets at CERN. The work involved:
  • an analysis of needs (in collaboration with specialists of beam physics and magnet construction);
  • definition of the experimental program and measurement procedures;
  • design, construction and commissioning of measurement equipment (several innovations, mostly in-house developments, given the highly specialized requirements);
  • the specification and procurement of suitable control, acquisition and analysis software (mostly sub-contracted either within CERN or to collaborating institutes);
  • implementation of a continuous calibration procedure;
  • optimization of the measurement steps within the workflow of magnets reception, test and preparation for installation, including statistical considerations on the required sampling;
  • measurement follow-up (training of operators), data reduction, analysis and reporting in synthetic form.
The LHC measurement campaign is the largest field mapping exercise ever performed on accelerator magnets.
1986 - 1996: Supermagnet, a suite of codes for the integrated analysis of superconducting magnet systems
Development and distribution (EU collaboration) of a series of magnet design and analysis codes that cover cable design and optimization, magnetic design, thermal analysis, AC loss calculation, stability and quench. The codes are presently in use at over 20 scientific institutions and industries.
