No full textA simple dynamic time-over-threshold circuit for high-resolution amplitude measurement
No full textThe dynamic time-over-threshold (dToT) method is a timing-based readout technique for pulse-height measurement of radiation detectors. After the leading-edge detection, the discriminator threshold is raised to allow precise pulse-height estimation over a wide dynamic range. A particularly simple circuit implementation of dToT is presented that delivers excellent amplitude resolution with minimal complexity. Experiments show that the resolution is sufficient to read out high-performance scintillators such as LaBr3:Ce without degrading their intrinsic energy resolution

No full textExclusive photoproduction of excited ρ mesons decaying to four pions in ultraperipheral Pb–Pb collisions at = 5.02 TeV
No full textThe intense photon fluxes from relativistic nuclei provide an opportunity to study photonuclear interactions in ultraperipheral collisions. In particular, it allows for the investigations of excited, light-flavour vector mesons. The measurement of coherently photoproduced π+π−π+π− final states in ultraperipheral Pb–Pb collisions at sNN=5.02 TeV is presented for the first time. The cross section, dσ/dy, times the branching ratio (ρ→π+π+π−π−) is found to be 47.8 ± 2.3 (stat.) ± 7.7 (syst.) mb in the rapidity interval |y| m1=1385±14(stat.)±3(syst.) MeV/ c2, Γ1=431±36(stat.)±82(syst.) MeV/ c2, m2=1663±13(stat.)±22(syst.) MeV/ c2 and Γ2=357±31(stat.)±49(syst.) MeV/ c2, respectively. The measured cross sections times the branching ratios are compared to recent theoretical predictions
Impact of trace amounts of water on the stability of Micro-Pattern Gaseous Detectors measured in (90-10)
No full textIn this study, we investigate the influence of humidity on the performance of various non-resistive Micro Pattern Gaseous Detectors, such as GEM, Thick-GEM, and Micromegas, operated with Ar-CO2 (90-10) gas mixture. The water content is introduced in a range of 0-5000 ppmV. It is observed that the presence of increased humidity does not significantly degrade any of the studied performance criteria. On the contrary, our measurements suggest an improvement in discharge stability with increasing humidity levels at the highest gains and fields. No significant difference is observed at the lower gains, indicating that humidity helps to reduce the rate of spurious discharges related to electrode defects or charging-up of the insulating layers. We conclude that adding a small amount of water to the gas mixture may be beneficial for the stable operation of an MPGD
