We investigate a detector scheme designed to measure the arrival of a particle at x = 0 during a finite time interval. The detector consists of a two state system which undergoes a transition from one state to the other when the particle crosses x = 0, and possesses the realistic feature that it is effectively irreversible as a result of being coupled to a large environment. The probabilities f...

ATLAS is a general purpose experiment which will operate at the LHC. In the main focus of ATLAS is the investigation of the nature of the electroweak symmetry breaking, and therefore the search for the Higgs boson. Electrons, photons, muons, tau and b-jets are important components of the possible physics signatures expected. The expected quality of particle-ID impose strong requirements upon th...

This review provides an overview of many recent advances in detector technologies for particle physics experiments. Challenges for new technologies include increasing spatial and temporal sensitivity, speed, and radiation hardness while minimizing power and cost. Applications are directed at several future collider experiments, including the Large Hadron Collider luminosity upgrade (sLHC), the ...

A model of radiation action by energetic heavy ions, inspired by a study of particle tracks in electron sensitive emulsion, has been successfully applied to many radiation effects in condensed matter, yielding quantitative descriptions and occasional predictions. Radiation effects are attributed primarily to secondary electrons. Each detector is imagined to be a collection of targets whose radi...

Particle identification, in particular the identification of charged pions and kaons, plays an important role for studies CP violation B Factory experiments. For BELLE detector at KEK B-Factory Japan, a threshold aerogel Cherenkov counter (ACC) has been used to separate kaons momentum range between 1.0 GeV/c 3.5 GeV/c. This paper gives brief description ACC design, construction, monitoring syst...
