158. A Charged Particle Identification Detector in the Forward Region of SuperB

P3 - PID and Photo Detectors

Poster

New generation flavor factories like SuperB require very good charged particle identification. In SuperB, the barrel region is covered by a new detector based on the successful BaBar DIRC – the FDIRC, see separate contribution at this conference. To extend this excellent coverage down in polar angle, an additional detector has been designed for the forward region. Thin enough to fit between...

EIGER is the next generation single photon counting x-ray detector developed at Paul Scherrer Institut for synchrotron based applications. It is a hybrid silicon pixel detector that features a 75x75 $\mu$m${}^2$ pixel size, a high maximum frame rate capability of ~22 kHz (independent on the detector size), double buffered storage for continuous readout and a negligible dead time between frames...

Poster

Bolometers have proven to be good detectors to search for rare processes because of their excellent energy resolution and for their extremely low intrinsic background. The CUORE experiment, that aims at studying neutrino-less double beta decay, is building a detector made of 988 TeO${}_2$ crystals, 0.750 kg each, kept at a temperature of 10 mK. In this kind of experiments, the capability of...

P3 - PID and Photo Detectors

Poster

In order to have access to the reaction $e^{+}{e}^{-}\to e^{+}{e}^{-}\gamma \gamma$ in the energy region of the phi meson production, new detectors along the (DAFNE) beam line have to be installed in order to detect the scattered $e^{+}{e}^{-}$. The HET detector is used for measuring the deviation of leptons from their main orbit by determining their position and timing so to tag gg physics events and...

258. New bi-dimensional SPAD arrays for Time Resolved Single Photon Imaging

P3 - PID and Photo Detectors

Poster

Time resolved imaging up to the single photon sensitivity is one of the most ambitious and important goals of photonics. In the last decades the time correlation analysis has been fundamental for the study of many scientific topics. Actually it has performed only by using the information of few points in the image. The implementation of such devices based on SPADs (Single Photon Avalanche...

236. Operation of proportional counters under high gas gain, high working gas pressure in mixed field of radiation.

P3 - PID and Photo Detectors

Poster

Gas gain is one of the main parameter of proportional counter. It was measured that this value depends on type of detected radiation and for beta particle is higher by (6-8)% than for X-rays. Over some value of current flowing threw the counter (Ic-critical current) the reduction in gas gain due to space charge defined by the time of evacuation of positive ions is observed. The value of Ic...

106. Particle ID, position and timing measurement with scintillating fibers readout by SiPMs

Dr Angela Papa (Paul Scherrer Institut)

P3 - PID and Photo Detectors

Poster

The silicon photomultiplier (SiPM) is a recent and established evolution of the avalanche photodiode (APD). This device is particularly appropriate for use in scintillation detection because of its high sensitivity, high quantum efficiency, and insensitivity to magnetic field (up to 4 T). Excellent time and energy resolution in addition to small size and high efficiency are crucial for...

65. Particle identification using the time-over-threshold measurements in straw tube detectors

P3 - PID and Photo Detectors

Poster

In the PANDA experiment, identification of charged particles in momentum region below about 1 GeV/c will be based on the measurement of energy losses in the central straw tube tracker. In order to make a choice between the charge integration and the time-over-threshold (TOT) techniques for the energy loss measurement, we performed tests of a prototype straw detector read out with a new...

P3 - PID and Photo Detectors

Poster

The time resolution of photon detection systems is important for a wide range of applications in physics and chemistry. It impacts the quality of time-resolved spectroscopy of ultrafast processes and has a direct influence on the best achievable time resolution of time-of-flight detectors in high-energy and medical physics. For the characterization of photon detectors, it is important to...

Poster

The properties of Carbon Nanotubes (CNT), the new allotropic status of carbon discovered in 1991, have been widely investigated in all possible application field. This new material in fact can be easily obtained chemically by CVD (Chemical Vapour Deposition) as a layer of nanotubes growth on a wide variety of materials. When growth on a semi conductive silicon surface, CNT create a...

Poster

New Cherenkov photon detectors are being developed for the upgrade of COMPASS RICH-1. The detectors are based on the use of THGEMs, arranged in a multilayer architecture, where the first layer is coated with a CsI film, acting as a reflective photocathode. The response of single layer THGEMs with various geometries and different conditions was extensively studied and photon detector...

Poster

The branching ratio (BR) for the decay $K^{+}\to {\pi }^{+}\nu \overline{\nu }$ is a sensitive probe for new physics. The NA62 experiment at the CERN SPS will measure this BR to within about 10\%. To reject the dominant background from channels with final state photons, the large-angle vetoes (LAVs) must detect photons with energies as low as 200 MeV with an inefficiency of less than ${10}^{-4}$, as well as...

Poster

The International Muon Ionization Cooling Experiment (MICE) will carry out a systematic investigation of ionization cooling of a muon beam, for the future Neutrino Factory and the Muon Collider. As the emittance measurement willbe done on a particle-by-particle basis, a sophisticated beam instrumentation is needed to measure both particle coordinates and timing vs RF in a harsh environment...

P3 - PID and Photo Detectors

Poster

Silicon PhotoMultipliers (SiPMs) are arrays of inverse polarized diodes operating in Geiger mode with a gain of 10${}^5$-10${}^6$, comparable with that of PMTs, thus showing single-photon sensitivity and excellent photon-counting capability. SiPMs show many advantages over PMTs, such as higher quantum efficiency, lower operation voltages and insensitivity to magnetic fields, however their main...
