Short-Lived PET Radioisotope Production in a Small Plasma Focus Device

The Investigation Capability of Plasma Focus Device for <sup>13</sup>N Radioisotope Production by Means of Deuteron Experimental Spectrum

“…They placed the target graphite ( ) 15 15 0.7 × × to a distance of 100 mm in front of deuteron beam within NX2 device so that the solid angle between deuterons and target graphite was 1.26 sr O = . The activity reported by Roshan et al within NX2 device with repetition rate of 1 Hz after 30 seconds of graphite bombardment was equal to 5.2 kBq [6]. This amount in this small device (1.7 kJ) is better than the reported activity of bigger devices.…”

“…In order to calculate α the same laboratory conditions [6], (a graphite target with dimensions (15 × 15 × 0.7) 100 mm away from the pinch) are considered. Figure 4 shows activity changes in terms of m (exponential function power in Equation (3)).…”

“…The effect of repetition rate on the amount of activity at frequencies of 1 Hz, 5 Hz, 10 Hz and 16 Hz during the bombardment time of 30 s (the time considered in the lab [6]), 300 s (1/2 of radioisotope half-life), 600 s (1 half-life), 1200 s (2 half-life) 1800 s (3 half-life) is investigated and its diagram is drawn.…”

“…Brzosko group [4] in the U.S., Angeli [5] in Italy, Roshan [6] in Singapore can be named. The amount of activity produced in Singapore group has remarkably increased.…”

“…The amount of activity produced in Singapore group has remarkably increased. Roshan et al [6] have carried out their experiments on a plasma focus device NX2. They placed the target graphite ( ) 15 15 0.7 × × to a distance of 100 mm in front of deuteron beam within NX2 device so that the solid angle between deuterons and target graphite was 1.26 sr O = .…”
