A new laser test stand for simulating charged-particle tracks
نویسندگان
چکیده
We report on the construction of a new laser test stand equipped with a 1064nm pulsed infrared YAG laser for simulating the passage of a charged particle in a silicon detector. The standard semiconductor repairing tool, the socalled laser-cutter, has been modified to have a newly developed optics which has the ability to reduce the light by the order of 106~108 and to adjust the spot size to several microns. As an application we measured the position dependence of the induced signals in a silicon-strip detector when the laser light hits in the region between the strips. The measurement has shown that this device is very effective in evaluating the detailed response of a silicon detector without using charged particles generated by accelerators.

متن کاملA new model for simulating colloidal dynamics
We present a new hybrid lattice-Boltzmann and Langevin molecular dynamics scheme for simulating the dynamics of suspensions of spherical colloidal particles. The solvent is modelled on the level of the lattice-Boltzmann method whereas the molecular dynamics is done for the solute. The coupling between the two is implemented through a frictional force acting both on the solvent and on the solute...
