   Sammanfattning : The neutron spectrometer TOFOR was installed at JET in 2005 for high-rate observation of neutrons from reactions between two deuterium (D) ions. Neutron spectrometry as a fusion plasma diagnostic technique is invoked to obtain information about the velocity states of fusion fuel ions. LÄS MER

7. 5. High Repetition Rate Laser Diagnostics for Combustion Applications

   Författare :Johan Sjöholm; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spray; diesel; optical engine; simultaneous; laser-induced fluorescence; fuel tracer; SLIPI; Raman; LII; laser diagnostic; combustion; high repetition rate; high-speed; PLIF; multi-YAG; LIF; fuel jet; Fysicumarkivet A:2012:Sjöholm;

   Sammanfattning : High repetition rate laser diagnostics has proven to be a useful tool for studying combustion phenomena. Laser techniques are, in general, relatively non-intrusive and have the potential to measure specific species at very low concentrations and with extremely high temporal resolution. LÄS MER
