Estimation of the Energy Deposited on the CNGS Magnetic Horn and Reflector
In the CNGS installation two magnetic

lenses, namely the horn and the reflector,
focus the secondary beam generated in the
target station. The gap between the horn and reflector is chosen to optimize a wide-band high-energy muon-neutrino
beam. These two focusing elements are two coaxial lenses similar in length but different in shape: the outer
conductor has a cylindrical shape whereas the inner conductor consists of a sequence of conical shapes to optimize
the focusing capacity. The evaluation of the heat load on the support structures is crucial since modifications in the
elements around the horn and reflector are under way and the support structures can be adapted to the heat load
found. Furthermore, the heat load in the whole horn area has been evaluated to optimize the cooling-ventilation
system. The FLUKA geometry input of the horn and reflector electrical connections has been notably improved in
order to accommodate the detailed striplines design to the thermal expansion. The energy deposited on the horn and
reflector as well as on their adjacent elements has been estimated using the FLUKA Monte Carlo package and results
are presented in this document.

High-performance targets intercepting multi
MW proton beams are the key toward intense
muon or neutrino beams. To achieve
this goal one must push the envelope of the
current knowledge on material science and material endurance and survivability to both short and long proton beam
exposure. The demand imposed on the targets of high power accelerators and the limitations of most materials in
playing such pivotal roles have led to an extensive search and experimentation with new alloys and composites.
These new high-performance materials and composites, which at first glance, appear to possess the right combination
of properties satisfying target requirements, are explored under accelerator target conditions where both shock and
irradiation damage are at play. Results of the on-going, multi-phased experimental effort under way at BNL involving
heavy irradiation of candidate materials using 200 MeV protons at the end of the BNL Linac as well as results on postirradiation
analysis assessing irradiation damage are presented.
Managing the Quality Assurance Documentation of Accelerator Components at XFEL and
PETRA III
Quality assurance (QA) documents are often
L. Hagge, J.A. Dammann (DESY)
collected locally on a per-component basis
by the manufacturing teams, while project
engineers require global evaluations of the QA documents e.g. for production control or during installation and
commissioning of the machine. DESY is using an Engineering Data Management System (EDMS) for supporting and
unifying the QA documentation of different accelerator components. The EDMS provides dedicated user interfaces
which are optimized for the needs of the specific engineering teams which are working on the components (including
industrial manufacturers), and at the same time integrates the QA documents into a central database for further overall
analysis and applications. The poster introduces the general structure of QA procedures, describes the benefits of
using an EDMS for QA documentation and reports experience from different applications at XFEL and PETRA III.
