CLIC Breakdown Studies TWIKI page

Welcome to the CLIC Breakdown Studies main TWIKI page. This page contains some basic information about the breakdown activities under the CLIC experiment, especially information which is useful for the people involved, such as experimental/simulation results, "clipart gallery" which is useful for presentations etc., links to useful references, and in general anything you feel belong here.

DC spark experiment

Information about the DC spark experiment may be added here - dimensions, voltages, typical observed data, pictures, links to publications etc.

Tricks for operation etc. may also be useful to have here.

ArcPic2D simulation

The ArcPic2D simulation software attempts to simulate the early stages of breakdown and plasma formation in the DC spark system. It is a electrostatic Particle-In-Cell (PIC) code with Monte Carlo collisions between the macro-particles. This simulation uses a 2D cylindrical symmetric coordinate system with co-planar electrodes on a uniform finite-difference grid. Particle boundary conditions, field boundary conditions (circuit models), and particle initial conditions are handled with easily swappable classes, enabling agile code development.

The code currently runs on one single CPU only.[SuperLU] is used to solve Poisson's equation.

The most up-2-date version of the code is found on CERN's SVN (restricted access): and a typical input file looks like:
