This paper proposes the use of fiber Bragg gratings (FBGs) for deflection monitoring a micromegas (MM) tracking particle detector to be installed at European Organization Nuclear Research during major upgrade experiment ATLAS within 2018. MM detectors are designed reach high spatial and time resolution, even if design is not yet finalized. One mandatory issue precise drift read-out electrodes and/or panel hosting electrodes. To this aim, FBG strain sensors proposed experimentally...
In this paper, we report about the deflection estimation of bi-dimensional structure by using fiber Bragg gratings (FBGs) as strain sensors embedded in and an algorithm based on classical beam theory with small deformation assumption. The proposed technique allows a real-time indirect structural monitoring solving existing difficulties measuring directly can be applied to well large structure, it is crucial high-energy physics, where particle detectors have measure position incoming...
Resistive Micromegas are nowadays a mature technology for High Energy Physics experiments. In the ATLAS experiment at CERN these detectors will operate hit rates up to 15 kHz/cm2. Future upgrades of existing experiments and new future accelerators require operation three orders magnitude higher. this paper we present design, construction test with pad resistive readout few mm2 in size. We aim precision tracking high rate environment without efficiency loss tens MHz/cm2. The detector layout...
The spectrometer of the ATLAS experiment has been designed to identify muon tracks with transverse momenta up 1 TeV/c. Its barrel section is made monitored drift tubes and resistive plate chambers (RPCs) arranged into 32 sectors, form two wheels surrounding interaction point. RPC subsystem provides level-1 trigger in it read out by a specific DAQ system. On-detector electronics pack data frames an event number assigned logic transmit them counting room optically. Data from each sector are...
Abstract We present the development of resistive Micromegas aiming at operation under high rates, up to tens MHz/cm 2 , focusing on optimisation spark protection layer and miniaturisation readout elements.
