The semiconductor pixel detectors Medipix2, Timepix and Medipix3 (256x256 square pixels, 55x55 μm each) are superior imaging devices in terms of spatial resolution, linearity dynamic range. This makes them suitable for various applications such as radiography, neutronography, micro-tomography X-ray defectoscopy. In order to control manage complex measurements a multi-platform software package acquisition data processing with Java graphical user interface has been developed. functionality the...
We report on laser cooling of a large fraction positronium (Ps) in free flight by strongly saturating the 1^{3}S-2^{3}P transition with broadband, long-pulsed 243 nm alexandrite laser. The ground state Ps cloud is produced magnetic and electric field-free environment. observe two different laser-induced effects. first effect an increase number atoms after time has spent long-lived 2^{3}P states. second one-dimensional Doppler Ps, reducing cloud's temperature from 380(20) to 170(20) K....
MoEDAL is designed to identify new physics in the form of long-lived highly ionizing particles produced high-energy LHC collisions. Its arrays plastic nuclear-track detectors and aluminium trapping volumes provide two independent passive detection techniques. We present here results a first search for magnetic monopole production 13 TeV proton-proton collisions using technique, extending previous publication with 8 data during Run 1. A total 222 kg detector samples was exposed forward region...
The MoEDAL experiment is designed to search for magnetic monopoles and other highly-ionising particles produced in high-energy collisions at the LHC. largely passive detector, deployed Interaction Point 8 on LHC ring, relies two dedicated direct detection techniques. first technique based stacks of nucleartrack detectors with surface area ~18m2, sensitive particle ionisation exceeding a high threshold. These are analysed offline by optical scanning microscopes. second trapping charged an...
Timepix3 detectors are the latest generation of hybrid active pixel Medipix/Timepix family. Such consist an sensor layer which is connected to readout ASIC (application specific integrated circuit), segmenting detector into a square matrix 256 $$\times $$ pixels (pixel pitch 55 $$\upmu m). Particles interacting in material create charge carriers, drift towards pixelated electrode, where they collected. In each pixel, time interaction (time resolution 1.56 ns) and amount created carriers...
MoEDAL is designed to identify new physics in the form of stable or pseudostable highly ionizing particles produced high-energy Large Hadron Collider (LHC) collisions. Here we update our previous search for magnetic monopoles Run 2 using full trapping detector with almost four times more material and twice integrated luminosity. For first time at LHC, data were interpreted terms photon-fusion monopole direct production addition Drell-Yan-like mechanism. The detector, consisting 794 kg...
We update our previous search for trapped magnetic monopoles in LHC Run 2 using nearly six times more integrated luminosity and including additional models the interpretation of data. The MoEDAL forward trapping detector, comprising 222 kg aluminium samples, was exposed to 2.11 fb−1 13 TeV proton–proton collisions near LHCb interaction point analysed by searching induced persistent currents after passage through a superconducting magnetometer. Magnetic charges equal Dirac charge or above are...
Abstract The miniaturized radiation camera MiniPIX TPX3 is designed for detailed and wide-range measurements of mixed-radiation fields present in many applications such as radiotherapy space outer orbit. highly integrated instrumentation utilizes a single connector control readout flexible quick deployment. device features an option to process the registered data on same with limited resolution basic particle-type resolving power. A novel processing technique exploits detector high...
The recent availability of large volume cerium bromide crystals raises the possibility substantially improving gamma-ray spectrometer limiting flux sensitivities over current systems based on lanthanum tri-halides, e.g., and chloride, especially for remote sensing, low-level counting applications or any type measurement characterized by poor signal to noise ratios. Russian Space Research Institute has developed manufactured a highly sensitive sensing observations planet Mercury from Polar...
The MoEDAL trapping detector, consists of approximately 800 kg aluminium volumes. It was exposed during Run-2 the LHC program to 6.46 fb^-1 13 TeV proton-proton collisions at LHCb interaction point. Evidence for dyons (particles with electric and magnetic charge) captured in detector sought by passing volumes comprising through a SQUID magnetometer. presence trapped dyon would be signalled persistent current induced On basis Drell-Yan production model, we exclude charge ranging up 5 Dirac...
