Geant4 is a software toolkit for the simulation of passage particles through matter. It used by large number experiments and projects in variety application domains, including high energy physics, astrophysics space science, medical physics radiation protection. Over past several years, major changes have been made to order accommodate needs these user communities, efficiently exploit growth computing power available advances technology. The adaptation multithreading, detector modeling...
A silicon microstrip vertex detector has been constructed and installed in the Collider Detector at Fermilab. The device designed to operate a hadron collider. It began collecting data May of 1992 functioned within specification. Technical details are presented on all aspects system its performance.
The LArIAT liquid argon time projection chamber, placed in a tertiary beam of charged particles at the Fermilab Test Beam Facility, has collected large samples pions, muons, electrons, protons, and kaons momentum range 300-1400 MeV/c.

We have developed particle detectors based on fused silica (quartz) Cherenkov radiators read out with microchannel plate photomultipliers (MCP-PMTs) or silicon (SiPMs) for high precision timing (σt ∼ 10-15 ps). One application is to measure the times of small angle protons from exclusive reactions, p+p→p+X+p, at Large Hadron Collider, LHC. They may also be used directional fluxes close external stored beams. The areas (cm2), but need active very ( 4 mm) intense LHC beam, and so must...
We propose the construction of, and describe in detail, a compact Muon Collider s-channel Higgs Factory.
Calorimeters implemented in future lepton colliders will inevitably suffer from leakage on account of space restrictions and need to operate strong magnetic fields. Both these circumstances affect the reconstruction jets give rise for corrections. In dual readout calorimeters, corrections are complicated by deal with more than one signal. this article we describe simulation studies a total absorption calorimeter.

We present the first measurement of negative pion total hadronic cross section on argon in a restricted phase space, which we performed at Liquid Argon In A Testbeam (LArIAT) experiment.

The performance of hadronic calorimeters will be a key parameter at the next generation High Energy Physics accelerators. A detector combining fine granularity with excellent timing information would prove beneficial for reconstruction both jets and electromagnetic particles high energy resolution.
