Source attack decoy-state quantum key distribution phase information
2016/1/23
Quantum key distribution (QKD) utilizes the laws of quantum mechanics to achieve information-theoretically secure key generation. This field is now approaching the stage of commercialization, but many...
A simple radionuclide-driven single-ion source
Source can barium ion recoil radioactive decay and nuclear detector steam
2014/12/18
We describe a source capable of producing single barium ions through nuclear recoils in radioactive decay. The source is fabricated by electroplating 148Gd onto a silicon α-particle detector and vapor...

2012/4/19
The paper is devoted to the proof of the uniqueness theorem for solution of the equation for the non-local ionization source in a glow discharge and a hollow cathode in general 3D geometry. The theore...
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...

Lyman-alpha Four-wave mixing Antihydrogen
2011/8/29
We demonstrate a reliable continuous-wave (cw) laser source at the 1 S–2 P transition in (anti)hydrogen at 121.56 nm (Lyman-α) based on four-wave sum-frequency mixing in mercury. A two-photon resonanc...
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 $...
