An induction charge detector yields the net charge and the time of flight of a particle. The unique ability to independently measure these two parameters sets apart this rather simple detection technique. The main shortcoming of this instrument is its high charge detection limit, resulting from the intrinsic noise of the detector electronics and the low signal associated with the charge to meas...

This paper proposes the median-type filters with an impulse noise detector using the decision tree and the particle swarm optimization, for the recovery of the corrupted gray-level images by impulse noises. It first utilizes an impulse noise detector to determine whether a pixel is corrupted or not. If yes, the filtering component in this method is triggered to filter it. Otherwise, the pixel i...

The detector description is an essential component that has to be used to analyse and simulate data resulting from particle collisions in high energy physics experiments. Based on the DD4hep detector description toolkit a flexible and data driven simulation framework was designed using the Geant4 tool-kit. We present this framework and describe the guiding requirements and the architectural des...

A pMsiblc realistic implemenwion of a method for inkmtion-free measurements. due to Elitzur and Vaidman. is proposed and discussed. It is argwd that the effed can be obse~ed in an optical laboratory. The interaction-free measurements of Elitzur and Vaidman [l] is a proposal to consider a well known device and ask a question which is, in a sense, opposite to what is usually asked. The suggested ...

The Hamiltonian of traditionally adopted (“Unruh-DeWitt”) detector models features off diagonal elements between the vacuum and the one particle states of the field to be detected. We argue that in realistic detector models the configuration “detector in its ground state + vacuum of the field” should be an eigenstate of the Hamiltonian, because it generally corresponds to a stable bound state o...

The ATLAS Pixel Detector is the innermost detector of the ATLAS experiment at LHC. Approximately 80 million silicon sensors allow to detect particle tracks and secondary vertices with very high precision. The ATLAS Pixel Detector is now in its final commissioning phase. A full characterization and qualification of the detector is currently performed: calibration procedures, special DAQ runs for...

We report a simplified flow cytometer design that makes use of negative dielectrophoresis (DEP) for particle focusing and integrated optical and AC impedance detectors to enable an inexpensive, compact and robust system for cell and particle characterization. This straightforward, modular design could be applied as a standalone instrument or as a particle detector in an integrated micro total a...
