| Abstract: | On the National Ignition Facility (NIF), hot electrons generated in laser heated Hohlraums are inferred from the >20?keV bremsstrahlung emission measured with the time integrated FFLEX broadband spectrometer. New high energy (>200?keV) time resolved channels were added to infer the generated >170?keV hot electrons that can cause ignition capsule preheat. First hot electron measurements in near ignition scaled Hohlraums heated by 96-192 NIF laser beams are presented. |
