Comprehensive beam tracing method is a simulation method that calculates refraction as well as reflection of sound. Due to the non-linear nature of Snell’s law, refraction (in contrast to reflection) is not a linear transformation. Because of this triangular beams used in comprehensive beam tracing simulation lose focus after refraction. In this paper the problem of non-linearity of refraction ...

We present concepts and beam test results of highly granular calorimeter prototypes optimized for the application of particle flow algorithms. A scintillator-steel hadron calorimeter using SiPMs as photodetectors (AHCAL) has been tested in electron and hadron beams at CERN and Fermilab in the energy range 1 – 80 GeV. More than 7600 SiPMs – the highest number ever used – performed well over the ...

This beam detector accepts the narrow pulses typically encountered in electron storage rings. It is composed of a peak detector with a threshold held constant by means of an automatic gain control (AGC) loop, and of a sampler. The output is proportional to the instantaneous position of the beam center of charge and is independent of the beam current. In addition, the very small phase shift of t...

Abstract. This paper deals with the detailed simulation studies of DEPFET detector position resolution, that has been intensely measured in 2006 at both DESY and CERN test beam facilities. As the multiple scattering has a strong effect on obtained results, a detailed simulation has had to be used to optimize the final geometry configuration. Moreover the final resolution of a system of telescop...

Recent High Pressure RF (HPRF) cavity experiment at MuCool Test Area (MTA) has used 400 MeV Linac proton beam to study the beam loading effect. When the energetic proton beam passes through the cavity, it ionizes the inside gas and produces the electrons. These electrons consume RF power inside the cavity. Number of electrons produced per cm inside the cavity (at 950 psi Hydrogen gas) per incid...
