The device which does the internal production of the radioisotope which is used for especially ideal for positron fault law

摘要

This invention is used for especially PET, it is the internal production device of the radioisotope.As for the device of this invention, it is processed because tolerance can be given vis-a-vis ion implantation at least, partly the vacuum chamber which has the inner surface which is inactivated vis-a-vis the nuclear reaction product (1) and the vacuum chamber the electrode of the pair where (1) is allotted in (4,5) with, the capacitor bank (2) and the aforementioned electrode (4,5) expedient in order to connect (3,16) it has the capacitor bank (2). The expedient (3,16) with, the electrode (4,5) discharge is made to cause in between, the plasma is generated because of this, it is something which generates the radioisotope by making the circumstance where the nuclear reaction happens one after another. Furthermore, the circuit which is suitable to this device, entire inductance and the vacuum chamber which do not become larger than 50nH connects the device of this invention, to (1), expedient in order to make the vacuum which is not larger than 10 ⁶ torrs (10) with, connects to the vacuum chamber (1), expedient in order to insert (11) has. The expedient (11) with, after the vacuum was created, one reaction gas is introduced at least under pressure, it is something which makes that formation of the plasma during discharge is guaranteed because of this, after that, obtains the shutting in state of the said plasma due to 1015 keV s/cm3 possible. Furthermore, as the device of this invention is installed in the vacuum chamber (1), extracts the gas in the gas chromatography cylinder, expedient in order to accumulate that gas is had.
