TRIUMF has been operating beryllium and graphite meson production targets for many years. Although the proton beam power of 100 kW at 500 MeV is lower, the beam densities and fluences are higher than most operating solid targets as other accelerators use rotating targets or larger beam spots. The beam size on the TRIUMF targets is maintained at 0.15 cm2 and this beam density leads to proton fluences of 1&amp;#183;10&lt;sup&gt;&lt;font size="-1"&gt;23</dc:description> <dc:publisher/> <dc:date>2005</dc:date> <dc:source>http://cds.cern.ch/record/928379</dc:source> <dc:identifier>http://cds.cern.ch/record/928379</dc:identifier> </dc:dc> </collection>
