### The Radiation Tolerant Electronics for the LHC Cryogenic Controls: Basic Design and First Operational Experience

J Casas-Cubillos, G Fernandez Penacoba & M A Rodríguez-Ruiz
The LHC optics is based in the extensive use of superconducting magnets covering 23 km inside the tunnel. The associated cryogenic system for keeping the magnets in nominal conditions is hence distributed all around the 27 km LHC tunnel and the cryogenic instrumentation submitted to the LHC radiation environment is composed of about 18’000 sensors and actuators. Radiation Tolerant (RadTol) electronics was designed and procured in order to keep the signals integrity against electromagnetic interference...

### Applications of nuclear data on short-lived fission products

G Rudstam, E Lund, P Aagaard & K Aleklett
The study of short-lived fission products gives information about the nuclear structure on the neutron-rich side of stability. The data are also of interest for various applications both to basic science and to nuclear technology. Some of these applications, taken up by the OSIRIS group at Studsvik, are described in the present contribution. (28 refs).

### Metallographic investigation of fracture behavior in ITER-style Nb$_{3}$Sn superconducting strands

M C Jewell, D C Larbalestier, P J Lee & A Nijhuis
In this work we specify the extent to which fracture in two ITER-style Nb3Sn composite strands occurs in a collective or individual manner, under mechanical tension and bending from the TARSIS apparatus at the University of Twente. A bronze-route strand from European Advanced Superconductors (EAS), which has very uniform, well-spaced filaments, has a widely distributed (200 μm) fracture field and exhibits a composite of individual and collective cracks. An internal tin strand from Oxford Instruments...

### Experimental quantum field theory

J S Bell
Presented here, is, in the opinion of the author, the essential minimum of quantum field theory that should be known to cultivated experimental particle physicists. The word experimental describes not only the audience aimed at but also the level of mathematical rigour aspired to. (0 refs).

### Insertion devices

J Bahrdt
The interaction of an insertion device with the electron beam in a storage ring is discussed. The radiation property including brightness, ux and polarization of an ideal and real planar and helical / elliptical device is described. The magnet design of planar, helical, quasiperiodic devices and of devices with a reduced on axis power density are resumed.

### Experimental aspects of heavy flavour production at the LHC

H Ruiz, M Smizanska, Th Lagouri, J Baines, A Morsch, R Ranieri, C Weiser & A Dainese
We review selected aspects of the experimental techniques being prepared to study heavy flavour production in the four LHC experiments (ALICE, ATLAS, CMS and LHCb) and we present the expected performance for some of the most significative measurements.

### Custom DC-DC converters for distributing power in SLHC trackers

S Orlandis, S Michelis, F Faccio, G Blanchot, G Spiazzi, P Mattavelli, C Fuentes, B Allongue & S Buso
A power distribution scheme based on the use of on-board DC-DC converters is proposed to efficiently distribute power to the on-detector electronics of SLHC trackers. A comparative analysis of different promising converter topologies is presented, leading to the choice of a magneticbased buck converter as a first conversion stage followed by an on-chip switched capacitors converter. An overall efficiency above 80% is estimated for the practical implementation proposed.
