  ABSTRACT: The ATLAS Muon Spectrometer is designed to measure the momentum of muons with a resolution of dp/p = 3% and 10% at 100 GeV and 1 TeV momentum respectively. For this task, the spectrometer employs 355,000 Monitored Drift Tubes (MDTs) arrayed in 1200 Chambers. Calibration (RT) functions convert drift time measurements into tube-centered impact parameters for track segment reconstruction. RT functions depend on MDT environmental parameters and so must be appropriately calibrated for local chamber conditions. We report on the creation and application of a gas monitor system based calibration program for muon track reconstruction in the LHC startup phase.

  ABSTRACT: Plasma Display Panels (PDP), the underlying engine of panel plasma television displays, are being investigated for their utility as radiation detectors called Plasma Panel Sensors (PPS). The PPS a novel variant of a micropattern radiation detector, is intended to be a fast, high resolution detector comprised of an array of plasma discharge cells operating in a hermetically sealed gas mixture. We report on the PPS development effort, including recent laboratory measurements.

  ABSTRACT: Performance demands for high and super-high luminosity at the LHC (up to 10³⁵ cm^-2 sec^-1 after the 2017 shutdown) and at future colliders demand high resolution tracking detectors with very fast time response and excellent temporal and spatial resolution. We are investigating a new radiation detector technology based on Plasma Display Panels (PDP), the underlying engine of panel plasma television displays. The design and production of PDPs is supported by four decades of industrial development. Emerging from this television technology is the Plasma Panel Sensor (PPS), a novel variant of the micropattern radiation detector. The PPS is fundamentally an array of micro-Geiger plasma discharge cells operating in a non-ageing, hermetically sealed gas mixture. We report on the PPS development program, including design of a PPS Test Cell.

  ABSTRACT: A radiation detector technology based on plasma display panels (PDPs), the underlying engine of panel plasma television displays, is being investigated. Emerging from this well-established television technology is the Plasma Panel Sensor (PPS), a novel variant of the micro-pattern radiation detector. The PPS is fundamentally a fast, high-resolution detector comprised of an array of plasma discharge cells, operating in a hermetically sealed gas mixture. We report on the PPS development effort, including proof-of-principle results of laboratory signal observations.

• Conference Proceeding: A gas monitor for the ATLAS Muon Spectrometer precision chambers

  ABSTRACT: The ATLAS Muon Spectrometer incorporates some 354,000 drift tubes assembled into 1200 monitored drift tube (MDT) precision chambers, with a total gas volume of 723,000 dm³. A gas mixture of 93% Ar and 7% CO₂ at 3 bar flows in a parallel feed at a rate of one chamber volume per day. Achieving the 80 mum single drift tube design resolution requires stringent gas quality control. We report on the design and initial performance of a dedicated MDT mini-chamber conceived for continuous monitoring of the ATLAS Muon Spectrometer MDT system operating gas. This chamber enables measurement of the drift spectra from which gas properties relevent to MDT calibrations are determined.
