Ils ont &eacute;galement trouv&eacute; leur place dans la soci&eacute;t&eacute; par leur utilisation croissante pour des applications dans des domaines tr&egrave;s divers, des sciences appliqu&eacute;es &agrave; la m&eacute;decine (recherche et applications cliniques) et &agrave; l&rsquo;industrie.

Making use of emerging technologies whose progress they helped to stimulate, they developed exponentially throughout the 20th century to become major tools for research today, not only in particle physics but also &ndash; as powerful radiation sources for probing matter &ndash; in atomic and molecular physics, condensed matter physics and materials science. They have also found applications in society, where they are increasingly used in a wide range of fields including applied sciences, medicine (research and clinical applications) and industry. The lecture will cover examples of these applications and further development opportunities.</span></p> <p style="text-align: justify;"><strong><em><span style="font-family:verdana,sans-serif; font-size:8.5pt">This lecture is organised within the framework of </span></em></strong><a href="http://cern60.web.cern.ch/en"><strong><em><span style="font-family:verdana,sans-serif; font-size:8.5pt">CERN60</span></em></strong></a><strong><em><span style="font-family:verdana,sans-serif; font-size:8.5pt"> events</span></em></strong></p> <p style="text-align: justify;"><em><span style="font-family:verdana,sans-serif; font-size:8.5pt">&nbsp;</span></em></p> <p><em><span style="font-family:verdana,sans-serif; font-size:8.5pt">&raquo; Suitable for all audiences</span></em></p> <p><em><span style="font-family:verdana,sans-serif; font-size:8.5pt">&raquo; Entrance free</span></em><span style="font-family:verdana,sans-serif">&nbsp;</span></p> <p style="text-align: justify;"><em><span style="font-family:verdana,sans-serif; font-size:8.5pt">&raquo; Seating is limited<br /> &raquo; Booking is essential: +41 22 767 76 76 <strong><span style="font-family:verdana,sans-serif">or</span></strong><strong><span style="font-family:verdana,sans-serif"> </span></strong></span><strong><span style="font-family:verdana,sans-serif; font-size:8.5pt"><a href="mailto:cern.reception@cern.ch">cern.reception@cern.ch</a></span></strong></em></p>
