In situ radioactivity measurements in a deep ocean environment are essential for marine environmental pollution monitoring and seabed geological exploration. the past, most widely used gamma spectrometers were based on towed instrumentation, which could only be operated underwater at depth of less than 1500 m. this study, compact spectrometer with small-size, light weight, low power consumption was designed working environment. This spectrometer, two parts: detector electronics, to work...
The time-of-flight (TOF) system in the Compressed Baryonic Matter (CBM) experiment is composed of super modules based on multi-gap Resistive Plate Chambers (MRPC) for high-denseness, high-resolution time measurement. In order to evaluate quality detectors during mass production, a distributed data readout developed meet with high rate 6.4Gbps, and related acquisition (DAQ) software implemented under Linux operating test verify feasibility method. this paper, DAQ focused collection, event...
A super module assembled with MRPC detectors is a component of TOF (Time Flight) system for the Compressed Baryonic Matter (CBM) experiment. Before modules are applied to CBM-TOF, their quality needs be evaluated. The readout electronics confronted tremendous challenge transmitting data at maximal speed 6 Gbps. In this paper, method CBM-TOF evaluation presented. parallel architecture based on Gigabit Ethernet designed meet requirement transmission rate. First, sent from front-end four groups...
A modified strain wedge model is presented to calculate the effect of scouring on responses a laterally loaded pile. The (SW) capable derive p-y curve for analysis vertical beam nonlinear foundation. To improve SW method, (MSW) developed by assuming lateral deflection pile get nonuniform soil in passive wedge. Treating weight above scour bottom as load, an equivalent depth obtained MSW consider hole dimensions. applicability problem under proved comparing with test and also FEM results. It...
Abstract In-situ radiation measurement and radionuclide identification in the ocean provide essential information for seabed geological marine ecological exploration. In this work, a small-sized CdZnTe-based gamma spectrometer with high energy resolution was designed automatic in-situ radioactivity environment down to depth of 4500 m. Four 10 × 5 mm 3 CdZnTe detectors were used, their spectra combined improve detection efficiency. Instead multi-stage analog circuits, digital processing...
The Compressed Baryonic Matter (CBM) experiment will investigate the quantum chromodynamics (QCD) phase diagram at high net baryon densities and moderate temperatures. CBM Time of Flight (TOF) system is composed super modules containing performance Multi-gap Resistive Plate Chambers (MRPCs). During mass production, each module assembled with MRPCs needs quality evaluation, which includes time measurement data readout. Read out electronics encounter challenge reading from a speed about 6...
Radiation measurement at underwater environment helps to get a better understanding on sedimentation, geological structure, radiation monitoring, and so on. However, reports about of natural are rare, especially in situ gamma measurement. Two spectrometers going be used Aiming different scientific goals, the can develop multiple kinds measurements, including dose energy spectrum rays. In this article, compatible data acquisition (DAQ) system is proposed. The DAQ provides features readout,...
A 3-inch phosphor screen using YAG single crystal as the substrate has been developed for compact projection displays. In order to obtain higher brightness, high resolution and resistivity against high-density electron bombardment, properties are improved from bulk property of well process. An which an optimum composition (formula available in paper) developed.
