Asymmetric multi-species alignment in drift wave turbulence
Asymmetric multi-species drift wave turbulence Plasma Physics
2012/5/29
Multi species turbulence in inhomogeneous magnetised plasmas is found to exhibit symmetry breaking in the dynamical alignment of a third species with the fluctuating electron density with respect to t...

Abstract: A semiclassical nonlinear collisional drift wave model for dense magnetized plasmas is developed and solved numerically. The effects of fluid electron density fluctuations associated with qu...
Basic randomness of nature and ether-drift experiments
Basic randomness of nature and ether-drif Experiments
2011/8/30
We re-consider the idea that quantum fluctuations might reflect the existence of an ‘objective randomness’, i.e. a basic property of the vacuum state which is independent of any experimental accuracy ...
Theory of cooperation in a micro-organismal snow-drift game
Theory micro-organismal snow-drift game
2010/11/12
We present a mean field model for the phase diagram of a community of micro-organisms, interacting through their metabolism so that they are, in effect, engaging in a cooperative social game. We show ...

The calibration and performance of the Silicon Drift Detector of the ALICE experiment during the 2008 cosmic ray run will be presented. In particular the procedures to monitor the running parameters (...
Charge collection in the Silicon Drift Detectors of the ALICE experiment
dE/dx detectors Particle tracking detectors
2010/3/15
A detailed study of charge collection efficiency has been performed on the Silicon Drift Detectors (SDD) of the ALICE experiment. Three different methods to study the collected charge as a function of...
In this thesis, we are concerned with the dynamics of spiral wave solutions to Reaction-Diffsion systems of equations, and how they behave when subject to symmetry breaking perturbations. We present a...
Design and implementation of the detector control system for the BESⅢ drift chamber cosmic ray test
Detector Control System drift chamber LabVIEW
2009/8/14
After the construction of the BESⅢ drift chamber, a long period of cosmic rays test is necessary to verify its performance. This also provides a good opportunity to integrate the detector readout ele...

After examination of the designed high voltage power supply system of the BESⅢ drift chamber in the beam test of the full length prototype of drift chamber, a full system covering all the channels of ...
Track reconstruction using the TSF method for the BESⅢ main drift chamber
BESⅢ detector track reconstruction track segment finder conformal transformation secondary vertex
2009/8/13
We describe the algorithm to reconstruct the charged tracks for BESⅢ main drift chamber at BEPCⅡ, including the track finding and fitting. With a new method of the Track Segment Finder (TSF), the resu...
