Ze worden dan in de ring geïnjecteerd. De ring van LEP bestaat, net als alle ringvormige versnellers, uit vele magneten die de elektrisch geladen deeltjes in een cirkelvormige baan houden (zodat ze binnen de ring blijven), RF-versnellers die de deeltjes versnellen met <a href="/wiki/Radiofrequente" class="mw-redirect" title="Radiofrequente">radiofrequente</a> golven, en <a href="/w/index.php?title=Quadrupool&action=edit&redlink=1" class="new" title="Quadrupool (de pagina bestaat niet)">quadrupolen</a> die de deeltjes gebundeld houden.

Dan worden deze groepjes elektronen en positronen met elkaar in botsing gebracht op de daarvoor bestemde plekken in de detectoren.
