A state-of-the-art detector, called sPHENIX is being planned at RHIC for measuring jets, jet correlations and upsilons to study the microscopic nature of the QGP. Precision vertexing and tracking, as well as calorimetry, will be provided over full azimuth and pseudorapidities of |eta| < 1.1. The data will be continuously recorded making use of the 15 kHz RHIC collision rate in the region of...
During 2013 to 2015 the CERN Axion Solar Telescope (CAST) has effectuated its final phase of solar axion searches providing a world leading limit on the axion photon coupling strength for ma< 0.02 eV. This sensitivity has been reached thanks to the development of novel detection systems, notably new Micromegas detectors with lower background levels, as well as a new X-Ray Telescope built...
The PRad experiment was recently performed
at Jefferson Lab in Hall B. It was designed
to measure the proton charge radius up to
a sub-percent precision through elastic electron
proton scattering process.
It reached very small 4-momentum
transfer squared region
($Q^2$ from $2 \times 10^{-4}$ to 0.1 $(GeV/c)^2$) for the first time.
To achieve the
experimental goal, a pair of large area
GEM...
Large areaGas Electron Multiplier (GEM) tracking detectors for the Super Bigbite Spectrometer (SBS) in Hall A at Thomas Jefferson National Laboratory (JLab) have been built at the GEM Detector Lab of the University of Virginia(UVa). The Proton Polarimeter Back Tracker of the SBS consists of 40 GEM modules, each with an active area of 60×50 $cm^2$. Given the open configuration of SBS, the...
Gas detector are very light instrument used in high energy physics to measure the particle properties: position and momentum.
Through high electric field is possible to use the Gas Electron Multiplier (GEM) technology to detect the particles and to exploit the its properties to construct a large area detector, such as the new IT for BESIII. The state of the art in the GEM production allow to...
Design and test of a custom front-end electronics for the readout of the new inner tracker of the BESIII experiment, carried out at BEPCII in Beijing, is presented.
An innovative cylindrical GEM detector with analog and time readout is under development to upgrade the Inner Tracker of the BESIII experiment at the BEPC-II e+e- collider of the Institute of High Energy Physics in Beijing.
The...
