Neutron activation measurement
[Objectives] Shot-integrated measurement of the total and 14 MeV neutron yield.
[Objectives] |
Shot-integrated measurement of the total and 14 MeV neutron yield. |
[Method] |
Metal foil is tranfered to the irradiation point in side the vacuum vessel by a pneumatic tube. After the shot, the activation gamma is measured by the High Purity Ge detector. |
[Position] |
P-15 sections, in the horizontal port. |

[Objectives] |
Measurement of the DD neutron spectra. |
[Detectors] |
Gridded He-3 ionization chamber |
|
NE213 liquid scintillator detector |
[Position] |
Basement under the U2 port of P-10 section. |
