The Cathode Strip Chamber (CSC) [1] Data Acquisition (DAQ) system for the CMS [2] experiment at the LHC [3] will be described. The CSC system is large, consisting of 218K cathode channels and 183K anode channels. This leads to a substantial data rate of ~1.5GByte/s at LHC design luminosity (10cms) and the CMS first level trigger (L1A) rate of 100KHz. The DAQ system consists of three parts. The ...
A novel green phase shifter system is proposed in this research. The system is developed by a combination of reconfigurable beam steering antennas and data acquisition (DAQ) boards. A combination of two reconfigurable beam steering antennas, located side-by-side, forms a spatial configuration structure with a fabricated ‘green’ element plank of rice husk placed in between. The concept of a spat...
A prototype of the ATLAS Prototype-1 DAQ Configuration Databases, based on persistent object managers, has been developed. We give here some details of the architecture, implementation and test results. Conclusions and plans for the further work are presented.
In this paper we report the development of the data acquisition system (DAQ) of the CANGAROO-III imaging Cherenkov telescope. Multi-pixel cameras at the prime focus of the first and second 10m telescopes consist of 552 and 427 PMTs, respectively. The charge from each PMT is measured with a ADC and the time each PMT is triggered is measured by a TDC with a time resolution of 1 ns. Since these mo...
J ava i s a key t ec hnology for t he next gene ra ti on of dat a ac qui s it i on s ys t em s (DAQ ). J ava has excellent features, but its performance is a weak point. We evaluated various Java benchmark progr am s wi t h a J ava i nt erpr et er , J ava J us t -I n-Ti m e com pi l er s (J I T), a J ava nat i ve code compiler (TowerJ) which generates native code, and a C compiler. The benchmar...
The Linear Collider TPC collaboration constructed a Large Prototype TPC (LPTPC) which is now installed at the EUDET facility, in DESY. The SiLC-collaboration (Silicon for the Linear Collider) will install position sensitive silicon strip sensors outside the field cage of the LPTPC, to provide precise tracking information. The data acquisition system (DAQ) is an adapted CMS readout system. The s...
Small-molecule organic cathodes in sodium-ion batteries (SIBs) face the challenge of dissolution. Herein, surface self-carbonization electrodes was proposed to overcome this bottleneck. As a proof concept, new soluble small-molecule compound [N,N′-bis(2-anthraquinone)]-1,4,5,8-naphthalenetetracarboxdiimide (NTCDI-DAQ) designed. Through precise control carbonization temperature and time under an...
The level-1 calorimeter trigger consists of three subsystems, namely the Preprocessor, electron/photon and tau/hadron Cluster Processor (CP), and Jet/Energy-sum Processor (JEP). The CP and JEP will receive digitised calorimeter trigger-tower data from the Preprocessor and will provide trigger multiplicity information to the Central Trigger Processor and region-of-interest (RoI) information for ...
This paper presents FADE-10G – an integrated solution for modern multichannel measurement systems, aimed on low latency, reliable transmission of measurement data from FPGA based front-end electronic boards (FEBs) to computer based node in the Data Acquisition System (DAQ), using standard Ethernet 1 Gbps or 10 Gbps link. Additionally to transmission of data, the system allows to reliably send s...
