Trigger-Induced Mechanical Resonances of Gating Grid Wires in the Multi-Wire Proportional Chambers of the ALICE TPC / Horn, C J (Vienna U.) ; Junique, A (CERN) ; Lippmann, C (Darmstadt, GSI) ; Mager, M (CERN) ; Musa, L (CERN) ; Richert, T (Lund U.) /ALICE TPC
A crucial issue in the design of modern multi-wire proportional chambers (MWPCs) is to avoide mechanical instabilities of thin and long wires that are held at high potentials [1]. Still, these structures are mechanically very sensitive and event-related (random) oscillations have been reported for drift tubes [2,3], where the gas ionisation originates the driving force..

LHCb Level-0 Trigger Detectors / Sarti, Alessio (Frascati)
The calorimeter and muon systems are essential components to provide a trigger for the LHCb experiment. The calorimeter system comprises a scintillating pad detector and pre-shower, followed by electromagnetic and hadronic calorimeters. [...]

Asymmetric and double-cathode-pad wire chambers for the LHCb muon system / Kachtchouk, A ; Lippmann, C ; Riegler, W ; Schmidt, B ; Schneider, T ; Souvorov, V
We present results from two types of Multi-Wire Proportional Chambers (MWPCs) with wire pitch of 1.5 mm and cathode–cathode distance of 5 mm intended for triggering purposes in the LHCb experiment. Both prototypes use cathode readout because this allows arbitrary segmentation in order to achieve the required granularity. [...]

Detector physics and performance : simulations of the MWPCs for the LHCb muon system / Riegler, W (CERN)
This note discusses some basic detector physics and performance parameters of the Multi Wire Proportional Chambers (MWPCs) for LHCb that were developed at PNPI. Detector physics topics like chamber geometries, potentials and fields, sensitivity to imperfections, electrostatic stability, wire diameter, gas properties and signal formation are discussed. [...]

Report on the quality of the LHCb-Muon four-gap MWPC produced at LNF / Dané, E ; Pinci, D ; Sarti, A
The LNF-LHCb team produced 185 four-gap Multi-Wire Proportional Chambers (MWPC). In this note we report the summary of the results of the panel quality controls and of the measurements performed on the assembled detectors

Precise gain measurement of the LHCb muon chambers / Dané, E (Frascati) ; Penso, G (INFN, Rome) ; Pinci, D (INFN, Rome) ; Sarti, A (Frascati)
The muon detector of the LHCb experiment, which will operate at the Large Hadron Collider (LHC) at CERN, consists of five muon tracking stations placed along the beam axis and equipped mainly with multi-wire proportional chambers (MWPC). In the present paper we report the results of a precise measurement of the gain of the MWPC’s as a function of the anode voltage. [...]
