摘要：
A set of nine tube sleeves was prepared by wrapping polyethylene film around a mandrel. Wall thicknesses ranged from a nominal 0.3 to 0.6 cm and diameters ranged from 2 to 5 cm. The sleeves were irradiated with a scanning 3 MeV electron beam and were dose-mapped by indexing and unwrapping the tube sleeves and measuring the dose by an FTIR spectroscopic technique. A Monte Carlo simulation model is also described which includes all important elements of 3-D geometry necessary to describe this experiment including window foil and beam scan angle. The simulation results were compared with the highly detailed dose distribution measurements in the tubing and the differences were found to be generally within 3 to 6 percent.
