NIF Beam Specifications

TRIUMF offers three different locations for testing with neutrons. The beam specifications for each location are given in the table below. The neutron flux is monitored with BF3 counters and dosimetry for calibrations is regularly performed using activation foils of nickel, aluminum, carbon, and gold.
