Infrastructure for Detector Research and Development towards the International Linear Collider
The EUDET-project was launched to create an infrastructure for developing and
testing new and advanced detector technologies to be used at a future linear
collider. The aim was to make possible experimentation and analysis of data for
institutes, which otherwise could not be realized due to lack of resources. The
infrastructure comprised an analysis and software network, and instrumentation
infrastructures for tracking detectors as well as for calorimetry.Comment: 54 pages, 48 picture
Vortex phase diagram in BSCCO with damage tracks created by 30 MeV fullerene irradiation
Using 30 MeV C60 fullerene irradiation, we have produced latent tracks of
diameter 20 nm and length 200 nm, near the surface of single crystalline BSCCO.
A preliminary transmission electron microscopy study shows evidence for a very
high density of deposited energy, and the ejection of material from the track
core in very thin specimens. The latent tracks reveal themselves to be
exceptionally strong pinning centers for vortices in the superconducting mixed
state. Both the critical current density and magnetic irreversibility line are
significantly enhanced. The irradiated crystals present salient features of the
(B,T) phase diagram of vortex matter both of pristine crystals, such as the
first order vortex phase transition, and the exponential Bose-glass line
characteristic of heavy ion-irradiated crystals. We show that the latter is
manifestly independent of the pinning potential.Comment: 10 pages, 13 figure
Calculated phase diagrams, iron tolerance limits, and corrosion of Mg-Al alloys
The factors determining corrosion are reviewed in this paper, with an emphasis on iron tolerance limit and the production of high-purity castings. To understand the iron impurity tolerance limit, magnesium phase diagrams were calculated using the Pandat software package. Calculated phase diagrams can explain the iron tolerance limit and the production of high-purity castings by means of control of melt conditions; this is significant for the production of quality castings from recycled magnesium. Based on the new insight, the influence of the microstructure on corrosion of magnesium alloys is reviewed
