Future accelerator projects, including the high-luminosity upgrade of the Large Hadron Collider, will rely on niobium–tin (Nb3Sn) alloys for their superconducting components, such as electromagnets. T...
Ring for test of nonlinear integrable optics
Ring test nonlinear integrable optics Nonlinear optics
2012/2/28
Nonlinear optics is a promising idea potentially opening the path towards achieving super high beam intensities in circular accelerators. Creation of a tune spread reaching 50% of the betatron tune wo...
Very High Precision Determination of Low-Energy Parameters: The 2-d Heisenberg Quantum Antiferromagnet as a Test Case
Precision Determination Low-Energy Parameters
2011/1/7
The 2-d spin 1/2 Heisenberg antiferromagnet with exchange coupling $J$ is investigated on a periodic square lattice of spacing $a$ at very small temperatures using the loop-cluster algorithm. Monte Ca...
Oedometric Test, Bauer's Law and the Micro-Macro Connection for a Dry Sand
Oedometric Test Micro-Macro Connection

What is the relationship between the macroscopic parameters of the constitutive equation for a granular soil and the microscopic forces between grains? In order to investigate this connection.
Cosmological Birefringence: an Astrophysical test of Fundamental Physics
Cosmological Birefringence Astrophysical test Fundamental Physics
2010/12/21
We review the methods used to test for the existence of cosmological birefringence, i.e. a rotation of the plane of linear polarization for electromagnetic radiation traveling over cosmological distan...
A quick test of the WEP enabled by a sounding rocket
WEP, EP equivalence principle general relativity sounding rocket
2010/12/20
We describe SR-POEM, a Galilean test of the weak equivalence principle, which is to be
conducted during the free fall portion of a sounding rocket flight. This test of a single pair of substances is ...
Some peculiarities of motion of neutral and charged test particles in the field of a spherically symmetric charged object in General Relativity
Motions classification Mass potential Stability conditions
2010/12/20
We propose the method of investigation of radial motions for charged and neutral test particles in the Reissner-Nordstr¨om field by means of mass potential. In this context we analyze special features...
I show that the CP-violating asymmetry in K0 vs K0→π+π－π0 decays differs from that in KL→π+π－, KL→π0π0 or the semileptonic KL transitions, if there exists CPT violation in K0-K0 mixing. A delicate mea...
A useful guide for gravitational wave observers to test modified gravity models
gravitational wave modified gravity models
2010/3/17
We present an extension of a previously suggested test of all modified theories of gravity that would reproduce MOND at low accelerations. In a class of models, called "dark matter emulators", gravita...
Design and test of a Multi-gap Resistive Plate Chamber with Long readout-strip (LMRPC)
LMRPC TOF gaseous detector
2009/8/14
A new kind (two end readout) of Multi-gap Resistive Plate Chamber with long readout-strip (LMRPC) is developed to be used at the large-area Muon Telescope Detector (MTD) at mid-rapidity at RHIC/STAR e...
Research and development of a 1.3 GHz 9-cell cavity test cryomodule were carried out by a collaboration group between IHEP (Institute of High Energy Physics) and TIPC (Technical Institute of Physics a...
The installation of the BESⅢ RPC system has been completed. Cosmic ray test results show that they perform very well in streamer mode and meet the BESⅢ requirements. We have tested several RPCs in the...
Test of Quantum Effects of Spatial Noncommutativity using Modified Electron Momentum Spectroscopy
Test of Quantum Electron Momentum Spectroscopy
