DESCRIPTION:Speakers: Paul Papka (Stellenbosch University)\nDirect monitor
 ing of targets for isotope production implies harsh conditions with large 
 neutron and gamma fields. These have implications on the type of instrumen
 t to use and how to extract information. Micro fission pocket detectors fo
 r nuclear power generation applications\, for example\, can sustain neutro
 n fluxes in the order of 1014n/cm2/s or more. This makes them suitable to 
 quantify neutron/gamma fluxes in real time but spectroscopic information i
 s not accessible.  An alternative was implemented at iThemba LABS to monit
 or leakage of radionuclide within the water cooling system. Water is sampl
 ed after the bombardment target and circulated in front of a germanium det
 ector. Even though the conditioning and transport of water imply delays\, 
 the specific transition lines identified in the gamma spectrum allow for f
 ine diagnostics of the bombardment targets. This can be used to deduce the
  type of target being bombarded\, monitor its condition and identify anoma
 lous leakage. Ultimately\, this can also be used to measure the integrated
  number of projectiles complementary to indirect beam current measurement 
 using non destructive probes.\n\nhttps://indico.tlabs.ac.za/event/82/contr
