A detailed study of hadronic interactions is presented using data recorded with the highly granular CALICE silicon-tungsten electromagnetic calorimeter. The predictions of several Monte Carlo GEANT4 models are compared with experimental data, taken at FNAL in 2008. The contribution recaps results published in 2015 and a set of new results available since the beginning of 2016. The published results...
The MicroBooNE experiment is a Liquid Argon Time Projection Chamber (LArTPC) detector located in the Booster Neutrino Beamline (BNB) at Fermilab at a baseline of 470 m and contains an active mass of 89 tons. The detector consists of a 2.5m × 2.3m × 10.4m TPC and includes an array of 32 PMTs used for triggering purposes. The inner TPC is housed in an evacuable and foam insulated cryostat vessel with...
Monolithic PET detector design is promising for low cost, high packing fraction, intrinsic depth-of-interaction (DOI) capability as well as potentially better energy and timing resolution compared to the conventional segmented crystal-based detector design. In this work, we developed a monolithic detector with 3D positioning capability and readout channel number compression. The detector contains...
Fast and accurate lost radioactive source positioning is of critical importance for the prevention of radiation damage in the accident. Traditional instruments with low detection efficiency cost lots pf time and energy, and may lead to harms to the operator's health. A portable detector to directly determine the incident angle of gamma rays is promising for the homeland security applications. In this...
High Energy Physics (HEP∗) experiments around the globe are using sophisticated equipments to record unprecedented amounts of data to discover some of the deepest mysteries of nature. Efficient parallelized frameworks are needed to achieve the scalability and performance requirements of such scientific data analyses. To accelerate data processing capability, many of the HEP experiments globally are...
In this work the experimental results are presented showing the spectroscopic performance of the ASIC multichannel charge-sensitive preamplifier of TRACE (TRacking Array for light Charged particle Ejectiles). The results were obtained connecting a silicon pad detector to a custom-designed preamplifier board with eight ASIC CSPs. The detector and the board were put in a vacuum chamber with a triple...
An independent monitoring system aiming for the detection of deviations from the prescribed treatment in hadrontherapy is presented. The system is based on prompt gamma-ray detection via scintillation detectors and the use of time-of-flight information. Test measurements at cyclotrons show the influence of degraders used in passive beam delivery systems. A dedicated data acquisition card has been...
PET detectors capable of measuring 511 keV photon time-of-fight (TOF) and depth-of-interaction (DOI) can improve resulting image quality and accuracy. In this work, we studied the timing performance of two TOF-DOI PET detector designs: (1) phoswich and (2) offset crystal arrays. The phoswich detector comprises a 3 × 3 × 20 mm3 element made from a 3 × 3 × 10 mm3 LYSO:Ce crystal with 42 ns decay time...
Medical PET scanners now exist in relatively large numbers around the world suggesting that certain physics experiments might be carried out during off-hours with these machines if organized into a global array of interlinked devices. Workers at Purdue, for example, have claimed to detect a possibly neutrino-induced annual periodicity in the decay rate of Cl-36 as the Earth traverses its elliptical...
In February 2016, the SuperKEKB positron-electron high-luminosity collider of the KEK laboratory (Tsukuba, Japan) started being commissioned. A dedicated commissioning detector, named BEAST2, has been used to characterize beam backgrounds before the Belle2 detector is rolled into the beams and to provide tuning parameters for Monte Carlo simulations. BEAST2 consists of a fiberglass support structure...
3He gaseous detectors have been widely used for homeland security and neutron scattering applications. Due to the 3He supply crisis, different alternative thermal neutron detection techniques have been studied in recent years. And the boron coated straw tube detectors (BCSD) have been chosen as one of the potential replacements of 3He gaseous detectors for the adequate supply and large cross section...
FASPAX (Fermi-Argonne Semiconductor Pixel Array X-ray detector) has been planned as a fast integrating area detector with wide dynamic range for time resolved applications at the upgraded Advanced Photon Source (APS). The detector will achieve a burst image rate of 13 MHz, matching the bunch rate of the proposed storage ring timing mode. A unique three gain charge splitting integration circuit will...
A modular, mass-producible, low-power, compact thermal-neutron counter has been developed to meet the needs for modern detector instruments and to compete with aging 3He-based counter systems. The Domino™ V5.4 neutron detector package is populated with four 1-cm2 active-area microstructured semiconductor neutron detectors (MSNDs). The detectors are calibrated to an intrinsic thermal neutron detection...
The COBRA Experiment intends to use CdZnTe coplanar grid (CPG) detectors to search for neutrinoless double beta-decay. The current demonstrator phase with 64 detectors with a volume of (10 × 10 × 10) mm3 showed that a long-term low-background experiment using CdZnTe is feasible. In the next stage, (20 × 20 × 15) mm3 detectors with a coplanar quad-grid (CPqG) will be used. The use of larger devices...
During 2015, the Large Hadron Collider (LHC) at CERN has reached the record-breaking center-of-mass energy of 13 TeV for proton-proton collisions. The LHC restarted operations successfully after a two-year technical stop, known as Long Shutdown 1 (LS1), needed for servicing and consolidating the CERN accelerator complex. The Compact Muon Solenoid detector, a general-purpose detector at LHC, benefited...
CALICE collaboration is developing highly granular calorimeters for future high energy e+e- colliders. Using Particle Flow Algorithms for individual reconstruction of particles in the jets, they provide currently the best jet energy resolution. At high jet energies (typically above 70–100GeV in the proposed detectors), the jet particle showers start to overlap, and the resolution is determined by...
Charge-sensitive preamplifiers (CSP) require high-valued feedback resistors as continuous-time reset devices: higher resistance values correspond to lower current noise and better spectroscopic performances. Designing integrated multi-channel CSP such resistors are generally left as external components or substituted with active transconductors. The former are bulky and not adequate for situations...
Based at CERN, the European Organization for Nuclear Research, the Large Hadron Collider (LHC) is the world's largest and most powerful particle accelerator. From 2025, the LHC will be upgraded to allow it to achieve a factor of 10 higher luminosity, which increases the rate of collisions, essential for probing new physics phenomena in the future. The route to high luminosity LHC (HL-LHC) involves...
This paper describes an optimization-based planning tool to assist planners in developing strategies for searching an urban area with gamma-ray detectors for the presence of a radiation source. Current search strategies (path and speed) are based on simple rules (e.g., move at normal traffic speed) and constrained by road networks and resources such as detection equipment, personnel, vehicles or time...
There has been a recent growth of activity in nonlinear time domain terahertz spectroscopy because of the development of a number of intense lab based sources and ultra-broadband detection schemes. Much of the interest stems from the possibility of exploring new physics by driving condensed matter far from equilibrium with THz fields in the 0.1 to 10MV/cm range [1]. The variety of different approaches...
