用高压倍加器加速能量为几百keV的氘离子,束流强度可达几十到几百mA量级。由于T(d,n)~4He反应在这一能区具有较高的反应截面,通常用它轰击氘钛靶产生中子作为强中子源。假定能量为400keV的氘离子束流强度为5mA,它打在靶上产生的热功率为2kW。如果靶子得不到有效的冷却,靶中吸附的氚将迅速地从钛层逸出,使中子源强度
High-pressure doublers are used to accelerate deuterium ions with energies of a few hundred keV, with beam intensities on the order of tens to hundreds of milliamperes. Since the T (d, n) ~ 4He reaction has a high reaction cross section in this energy region, it is usually used to bombard the target of deuterium-titanium to produce neutron as a strong neutron source. The deuterium ion beam with an energy of 400 keV is assumed to have a beam intensity of 5 mA and its thermal power on the target is 2 kW. If the target is not effectively cooled, the target adsorbed tritium will quickly escape from the titanium layer so that the neutron source intensity
