Heat Load and Stress Studies for an Design of the Photon Collimator for the ILC Positron Source
ILC collimator material stress high power beam absorption heat loads
2012/2/28
The ILC baseline design for the positron source is based on radiation from a helical undulator to produce positrons in a thin target. Since the photon beam created in the helical undulator is circular...
The Cusp as a Source of Magnetospheric Particles
Satellites plasma the solar wind magnetic sheath origin diamagnetic cavities the dipole field
2017/3/23
Observations made by a number of satellites have shown that plasma of solar wind/magnetosheath origin enters the high altitude polar cusp creating diamagnetic cavities of large dimensions. The Earth's...
There are no Static Solutions in Source-Free Non-commutative $U_{\star}(1)$ Gauge Theory
Static Solutions Source-Free Non-commutative
2010/12/24
The vanishing of self-stress for static systems excludes finite energy time-independent solutions of source-free $U_{\star}(1)$ theory in (3+1) dimensions. This implies that static solutions in case $...
A thermal field theory derivation of the source term induced by a fast parton from the quark energy-momentum tensor
thermal field theory derivation source term induced fast parton quark energy-momentum tensor
2010/12/29
I derive the distribution of energy and momentum transmitted from a fast parton to a medium of thermalized quarks, or the source term, in perturbative thermal field theory directly from the quark ener...

2017/3/23
Energetic particle instrumentation on the Polar satellite has discovered that significant fluxes of energetic particles are continuously present in the region of the dayside magnetosphere where they c...
Is the Cusp a Source or a Sink for Magnetospheric Energetic Particles?
High-energy particles the earth's magnetosphere particle particle flux
2017/3/23
Energetic particles have been observed to be continuously present in the dayside region of the Earth magnetosphere associated with the cusp where they can not be stably trapped. Particle tracing resul...
