Waveform digitization is an important research direction in high-energy physics experiments. Compared to the solution based on high speed ADC, switched capacitor array (SCA) has advantages in high sampling rate, low power consumption, and easy multi-channel integration. However, the dead time of SCA is a limitation for many high hit rate applications. In order to reduce the quantization time...
Recently, multi-channel waveform digitizer is increasingly used for new detector research. We will describe a novel real-time digitizer based on the latest multi-channel Analog-to-Digital Converter (ADC) for radiation detector applications. The digitizer can be configured as 16, 32, 64, 128 channels for different kinds of pixelized detectors. ADS52J90 chip, which is a high-speed,...
SliT is the new silicon-strip readout chip for the measurement of the muon anomalous magnetic moment $(g-2)$ and electric dipole moment (EDM) at J-PARC. The readout chip is required to tolerate a high hit rate of 1.4 MHz per strip and to have deep memory for the period of 40 $\mu$s with 5 ns time resolution. To satisfy the experimental requirements, we have developed a series of readout chip...
In high energy physics detection technology, X-ray polarization detection experiment is an important means to study astrophysics. One of the most commonly used two-dimensional detectors is the photoelectron track pixel detector. The readout electronics system of pixel detector is composed of several modules. With the development of high energy experiment, the readout electronics system of...
4πβ − γ coincidence counting has been widely
applied in the absolute radioactivity measurement for its high
accuracy and enabling measurement of most radionuclides without any specific values being assumed. The 4πβ − γ method
has a lot of variants according to the radionuclide and detector
types, among which the digital coincidence counting (DCC) is
quite outstanding. the DCC routine...
An extended modification phase of the superconducting fusion experiment Wendelstein 7-X was completed late 2021 after installing actively cooled divertor units and the integration or modification of new technical components and diagnostics. Currently, the commissioning of the W7-X experiment is underway. First plasma operation is scheduled to take place at the end of September 2022, and...
In this paper, the HiBeam-T, a time projection chamber (TPC) for monitoring the position and profile of heavy ion beams in a real-time manner, has been designed. This gaseous detector features its readout with an array of forty Topmetal-II− CMOS pixel sensors, each of which has 72 x 72 pixels with a size of 83 μm x 83 μm. The detector part consists of the charge drift and charge collection...
A very fast pulse readout ASIC, NTIMP1, with 1.2V power supply is presented in this work. It is going to be used as front-end electronics (FEE) for reading out the timing resistive plate chambers (RPCs) in the time of flight (TOF) wall of the compressed baryonic matter (CBM) experiment of the the High Intensity Heavy Ion Accelerator Facility (HIAF), China. NTIMP1 is fabricated using 0.13μm...
The Trigger and Data Acquisition system of the ATLAS experiment at the Large Hadron Collider at CERN is composed of a large number of distributed hardware and software components which provide the data-taking functionality of the overall system. During data-taking, huge amounts of operational data are created in order to constantly monitor the system. The Persistent Back-End for the ATLAS...
CMOS pixel sensors are widely used as Inner Tracker System (ITK) detector for their precise spatial resolution, low noise, fast reaction, and low material budget. STCFpix is a CMOS pixel sensor under development for the ITK in Super Tau-Charm Facility (STCF),which is expected to be a 2×2 cm$^2$chip containing 16 K pixels. In the context of the Inner Tracker data path, a STCF Read-Out...
In consideration of control requirement for experimental conditions in current physical experiment, it continually products vast quantities of control request and monitor data. The characteristic of large-scale physics experiment is taken into account, including remote site, varied device, vast observed value. A control system was developed, supports to communication with custom-made hardware,...
