Lattice design and expected performance of the Muon Ionization Cooling Experiment demonstration of ionization cooling

Muon beams of low emittance provide the basis for the intense, well-characterized neutrino beams necessary to elucidate the physics of flavor at a neutrino factory and to provide lepton-antilepton collisions at energies of up to several TeV at a muon collider. The international Muon Ionization Cooling Experiment (MICE) aims to demonstrate ionization cooling, the technique by which it is proposed to reduce the phase-space volume occupied by the muon beam at such facilities. In an ionization-cooling channel, the muon beam passes through a material in which it loses energy. The energy lost is then replaced using rf cavities. The combined effect of energy loss and reacceleration is to reduce the transverse emittance of the beam (transverse cooling). A major revision of the scope of the project was carried out over the summer of 2014. The revised experiment can deliver a demonstration of ionization cooling. The design of the cooling demonstration experiment will be described together with its predicted cooling performance.The work described here was made possible by grants from the Science and Technology Facilities Council (UK), the Department of Energy and National Science Foundation (USA), the Instituto Nazionale di Fisica Nucleare (Italy), the Bulgarian Academy of Sciences, the Chinese Academy of Sciences, the Dutch National Science Foundation, the Ministry of Education, Science and Technological Development of the Republic of Serbia, the European Community under the European Commission Framework Programme 7 (AIDA project, Grant Agreement No. 262025, TIARA project, Grant Agreement No. 261905, and EuCARD), the Japan Society for the Promotion of Science and the Swiss National Science Foundation in the framework of the SCOPES programme.

Conductivity and Thermoelectric Power of the Newly Processed Polyacetylene

Temperature dependent electrical conductivity and thermoelectric power are measured for the newly processed polyacetylene film doped with transition metal halides. Results of both four-probe and Montgomery methods for the dc conductivity measurement are presented. The four-probe results are somewhat anomalous. At present, the Montgomery measurement results show the maximum conductivit, δmax = 30,000 S/cm at T = 220K in the FeCl3 deped stretch-oriented-polyacetylene. Quasi-linear temperature dependent thermoelectric power are observed for the samples indicating that the doped polyacetylenes are metallic. Although high anisotropies are observed in electrical conductivity for these samples, the thermoelectric power data are isotropic, which suggest that the fibrillar orientation is not perfect in one direction. The possibility of Kondo-effect like couplings in these samples are discussed
