The Beijing Electron Spectrometer III (BESIII) is a multi-purpose detector that collects data provided by the collision in the Beijing Electron Positron Collider II (BEPCII), hosted at the Institute of High Energy Physics of Beijing. Since the start of its operation, BESIII has collected the world's largest sample of J/psi and psi(2s). Due to the unprecedent luminosity of the BEPCII, the most ... More

We have improved the self-stretching GEM assembly technique that was initially developed at CERN for the CMS GEM upgrade project. With this improved technique, we can build GEM detectors at a scale of > 1m that still preserve very good gain uniformity. The technique results in high-quality stretching of GEM foils and good gas tightness in GEM detectors. This report presents details of the impr ... More

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 c ... More

A triple gas electron multiplier (GEM) detector with an active area of 10x10 cm2 was constructed and tested for x-rays imaging using a 256 channel 2D x-y strips readout. The study includes optimization of GEM operating high voltage, x-ray tube distance, x-ray tube high voltage, the best x-ray filter, best ratio of Ar/CO2 gas mixture. A 90Sr beta source also was used. The result of the study shows ... More

The Large Hadron Collider (LHC) will be upgraded in several phases that will allow to significantly expanding its physics program. After the expected long shutdown in 2018 (LS2) the accelerator luminosity will be increased to 2 − 3 × 1034 cm^−2s^−1 exceeding the design value of 1 × 1034 cm^−2s^−1 allowing the CMS experiment to collect approximately 100 fb^−1/year. A subsequent upgrad ... More
