MICE: The International Muon Ionization Cooling Experiment: Phase Space Cooling Measurement
MICE is an experiment with a section of an ionization cooling channel and a
muon beam. The muons will be produced by the decay of pions from a target
dipping into the ISIS proton beam at Rutherford Appleton Laboratory (RAL). The
channel includes liquid-hydrogen absorbers providing transverse and
longitudinal momentum loss and high-gradient radiofrequency (RF) cavities for
longitudinal reacceleration, all packed into a solenoidal magnetic channel.
MICE will reduce the beam transverse emittance by about 10% for muon momenta
between 140 and 240 MeV/c. Time-of-flight (TOF) counters, a threshold Cherenkov
counter, and a calorimeter will identify background electrons and pions.
Spectrometers before and after the cooling section will measure the beam
transmission and input and output emittances with an absolute precision of
0.1%.Comment: Submitted to NuFact09 proceedings; 1 LaTeX file plus 2 postscript

Faking it : counterfeiting and consumer contradictions
Fashion counterfeiting is a multimillion pound business and one which relies on the complicity of the consumer. Frequently seen as a victimless crime, it is a difficult trade to control because as long as consumers desire brands, the greater the market for counterfeits. In this study we consider the way in which consumers relate to fake brands and the implications of counterfeit for consumers creating their identity through commodities. The results point to an inherent and fundamental contradiction in consumers views on counterfeit, willing to buy and wear the fakes but condemning the duplicity of those who do
Study made of corrosion resistance of stainless steel and nickel alloys in nuclear reactor superheaters
Experiments performed under conditions found in nuclear reactor superheaters determine the corrosion rate of stainless steel and nickel alloys used in them. Electropolishing was the primary surface treatment before the corrosion test. Corrosion is determined by weight loss of specimens after defilming
