During the ATLAS phase II upgrade, tracking system of experiment will be replaced by an all-silicon detector called inner tracker (ITK) with a pixel as most part. The monitoring data new aggregated from on-detector ASIC Monitoring Of Pixel System (MOPS) and sent to Detector Control System(DCS) using interface MOPS-HUB. hardware components MOPS-HUB, firmware specifications for FPGA MOPS-HUB its ...

Two micro crystal element (MiCE) detector unit designs are evaluated. The detector units are built using highly packed arrays of 0.8 0.8 6 mm mixed lutetium silicate (MLS) crystals. The first detector unit, MiCE1, consists of a 5 5 array of 0.8 mm 0.8 mm 6 mm MLS crystals. The detector unit is coupled to four channels of a Hamamatsu multichannel photomultiplier tube (PMT) via a 2 2 array of 2 m...

In this paper the CMOE detector proposed in 111 is modified to cope with a varying SNR of the signal of interest in a multi-user environment. The detector is applied to a DS-CDMA system, where several users transmit data simultaneously and asynchronously over a noisy, frequency selective power-line channel. A comparison is performed between the improved CMOE detector and a RAKE receiver for a n...

In January 22, 2002, KamLAND started the data-taking. The KamLAND detector is a complicated system which consists of liquid scintillator, buffer oil, spherical balloon and so on. In order to maintain the detector safety, we constructed monitoring system which collect detector status information such as balloon weight, liquid scintillator oil level and so on. In addition, we constructed continuo...

Background: A variable resolution X-ray (VRX) CT scanner provides a great increase in the spatial resolution. In VRX CT scanners, the spatial resolution of the system and its field of view (FOV) can be changed according to the object size. One of the main factors that limit the spatial resolution of VRX CT scanner is the effect of the X-ray focal spot. Materials and Methods: A theoreti...

Direct sequence code division multiple access (DS-CDMA) is a popular wireless technology. This paper presents comparative study between linear multiuser detectors, optimal multiuser detector, and conventional single user matched filter in DS-CDMA system. Analysis and simulations are conducted in synchronous AWGN channel, and Gold sequence is used as the spreading codes. The study shows that opt...

We study the quantum Zeno effect in the case of indirect measurement, where the detector does not interact directly with the unstable system. Expanding on the model of Koshino and Shimizu [Phys. Rev. Lett., 92, 030401, (2004)] we consider a realistic Hamiltonian for the detector with a finite bandwidth. We also take explicitly into account the position, the dimensions and the uncertainty in the...
