Lighting Through A Wall Experiment

The alps collaboration runs a light shining through a wall lsw experiment to search for photon oscillations into weakly interacting sub ev particles wisps inside of a superconducting hera dipole magnet at the site of desy.

Lighting through a wall experiment.

Several different calculational methods are employed and compared and in all cases we retain a nonzero axion mass. Nevertheless there are quite a number of experimental collaborations around. To leading order we find that when the photon frequency ωis very close to the axion mass m there is a threshold cusp. The experiment is to search for particles that can shine light through a wall.

In particular several groups have started light shining through a wall experiments based on magnetic field and laser both continuous which is very demanding in terms of detector background. Light shining through a wall setup. The wavy line indicates the photon field and the dashed line the axion field. The idea behind the double slit experiment is that even if the photons are sent through the slits one at a time there s still a wave present to produce the interference pattern.

Recently axionlike particle search has received renewed interest. Like the wimps the suspected particle does not belong to the standard model of particle physics nor is it clear that it actually exists. The analysis of light shining through a wall experiments. Shining light through walls.

An x ray version of this experiment has recently been proposed by rabadán et al. In this paper we have described and characterized our apparatus and demonstrated the data analysis procedures. Unfortunately with present and near future technologies the opportunity to observe light shining through walls via these effects is completely out of question. In modern physics the double slit experiment is a demonstration that light and matter can display characteristics of both classically defined waves and particles.

However very feeble gravitational and electroweak effects allow for this exotic possibility. At first glance this sounds crazy. Moreover it displays the fundamentally probabilistic nature of quantum mechanical phenomena. An example of this is the so called axion.
