| Abstract | Possibility of creating the liquid lead target with parameters, optimum for the NLC positron source, is investigated. Target has a form of titanium vessel, filled with liquid lead, pumped through. The energy deposition in target is characterized by 35 kW average power and up to 250 J/g specific energy at optimum beam sigma 0.6 mm. The use of pumped through liquid lead as target material solves both the problems of power evacuation and target survival. The window for beam exit is made of both temperature and pressure resistive material − the diamond-like ceramic BN. The optimal conditions for positron capture in a frame of the concept of new NLC positron source [1] include the small size of primary electron beam (σb = 0.6 mm) and small, practically null, distance |
