:Title: Map of a HiSPARC detector inside the KASCADE experiment
:Tags: Foreach;Styles;Spy library;Physics;Astronomy
:Author: David Fokkema
:Slug: kascade-map
The KASCADE experiment is a 200 × 200 m array detecting cosmic rays. It
consists of 252 detector stations spaced 13 m apart and has taken data
from 1996 to 2009. It continued to host a few guest experiments,
including LOPES, TAUWER and HiSPARC, until early 2013. This map shows the
layout of KASCADE and the location of the HiSPARC station. This figure is
a minor revision of the one included in
[my PhD thesis](http://dx.doi.org/10.3990/1.9789036534383).
