“…EASIROC modules [13] were used to control the MPPCs and read out signals from them. A VME-based data acquisition system [14] that consists of V1190A time-to-digital converters (CAEN) [15] was used for recording their signals. The β-ray hit positions on these planes were determined by PSFs, and the source positions of β-rays could be tracked back.…”

Nuclear magnetic resonance (NMR) using β-decay radioisotopes, known as “β-NMR,” is used for research in nuclear physics. Recently, nuclear magnetic moments of β-decay radioisotopes have been precisely measured by β-NMR. Therefore, β-decay radioisotopes can be used for NMR spectroscopy in material sciences. Nuclei, whose spin is zero, such as 12C and 16O, cannot be used in conventional NMR. However, nonzero-spin radioactive isotopes of carbon and oxygen can be used in β-NMR. This advantage is powerful for investigating organic materials that cannot be investigated using conventional NMR. A technique is being developed to extend β-NMR for imaging use in magnetic resonance imaging (MRI). In this study, the imaging function was realized by installing β-ray tracking detectors in a β-NMR device. Nuclear-spin-polarized radioisotopes were injected into a sample, and β-rays were emitted from their positions. Consequently, one could track back β-ray source positions on the sample. These detectors were installed into a dipole magnet to observe the magnetic resonances. A radio frequency coil was installed surrounding the sample. By combining information about the β-ray tracks and magnetic resonances, it was possible to obtain NMR spectra and images. This method is called “β-MRI.” The system was evaluated, and its performances were estimated.

On the aircraft, the utilities management computer completes the information interaction with the utilities systems and the avionics system, which plays a vital role in ensuring the safe flight of the aircraft. This paper mainly discusses the voice alarm mechanism of utilities systems based on utilities management computer. For the voice alarm that occurs during the flight, the fault inspection and mechanism analysis are carried out. For the reported bus access timeout fault, the fault location is completed and a solution is proposed. It will provide important support for the development and guarantee of the computer to ensure the safe flight of the aircraft and the utilities management.

Modern day complex experiments in physics demand highly efficient data acquisition (DAQ) systems capable of acquiring a large number of signals with a very high resolution and near zero dead time, without compromising on the event rate handling capability. To cater to the ever growing demands of the DAQ systems, an intelligent controller with a sequencer and an in-built busy logic has been developed. The heart of the controller is a field programmable gate array that provides (a) a sequencer engine, which holds a list of read–write commands that will be executed upon receiving a valid trigger, (b) a dual port random access memory divided into two blocks of 16 kbytes, each of which is configured in a ping-pong fashion to support data acquisition and data transfer functionalities simultaneously, thereby reducing the dead time, (c) a busy logic interface that validates the master strobe or trigger, a scalar for triggers received, and a time stamp engine for time stamping the events with 10 ns interval, (d) the Versa Module Europa (VME) backplane interface for 32 bit data transfer standards of the VME, and (e) a superspeed universal serial bus communication interface to transfer the data to a computer/single board computer (SBC). The SBC is capable of booting locally or through net via a preboot execution environment from a netboot server, and it contains the driver, libraries, and data server for data collection. A throughput of 32 megabytes per second (MB/s) has been achieved with an event size of 288 signals at an event rate of 30 kiloevents per second with medium slow slave modules, which may further increase up to 45 MB/s with faster slave modules. The VME controller supports an event size (number of signals) of up to 1023 in a single VME crate. Thus, this sequencer engine based VME crate controller development facilitates collection of a high volume of data with a large number of signals at higher event rates and the least dead time; it is named as Readout Ordained Sequencer Engine.
