In this article, construction, operation, and performance of the RICH detector of Fermilab experiment 781 (SELEX) are described. The detector utilizes a matrix of 2848 phototubes for the photocathode to detect Cherenkov photons generated in a 10m Neon radiator. For the central region an N0 of 104 cm , corresponding to 13.6 hits on a β = 1 ring, was obtained. The ring radius resolution measured ...

We measured the timing resolution of TOF counters by means of Cherenkov-light detection with a Micro-Channel Plate PhotoMultiplier Tube, and attained sTOF 1⁄4 6:2 ps using 3GeV=c pion-beams with a readout electronics of 4.1 ps resolution. The optimum radiator thickness was examined and the detectable number of photo-electrons was analyzed. r 2006 Elsevier B.V. All rights reserved. PACS: 85.60.H...

A dual-band Planar inverted-F antenna (PIFA) for wireless applications has been presented in this paper. The proposed antenna is compact in size and design on FR4 substrate. The antenna consists of a slotted radiator supported by shorting walls and a small ground plane. Square shaped slot in radiating patch have been used to introduce dual band operation into the proposed antenna. The structure...

In this paper recent developments of RF front-end system based on the active integrated antenna design concepts are presented. Thanks to the enhancements in the design of special antennas working as radiator as well as providing the other circuit functionalities, the antenna-integrated RF front ends have been capable of improving the circuit-efficiency and compactness. These enhancements are il...

Lead can be an ideal medium for the detection and study of neutrinos. Such a detector may be realized through the use of a lead perchlorate (Pb(ClO4)2 ) solution as a Cerenkov radiator. The basic physical properties of lead perchlorate solution are given and preparation of the solution for use in a Cerenkov detector is described. Results from investigations of light transmission in lead perchlo...
