Description
Estimation shows that powerful Gas-Dynamic Trap operated for generating neutrons at continuous rate 1E18 1/s will release high particle flux (∼3E22 1/s of D/T mixture) out of confinement region. The vacuum vessel of the Gas-Dynamic Trap consists of central cylindrical confinement volume and two plasma expansion vessels. In order to sustain the adequate vacuum conditions in the expansion vessels (<0.04 Pa) a continuously operating pumping system has to be incorporated into their design. The required pumping speed for each expansion vessel is estimated as 750 m^3/s. In addition, the vacuum system has to remove selectively He atoms (∼1E18 1/s). The report considers possible variants of the neutron source vacuum system with respect to its reliability, safety and cost.
