Safety Considerations for Laser Power on Metals in Contact with High Explosives-Experimental an Calculational Results

PDF Version Also Available for Download.

Description

Measurements have been made to determine safe levels of laser exposure on common metals used in contact with high explosive (HE) samples. Laser light is often used on metals in contact with HE during alignment procedures and experimental data collection. The measurements look at temperature rise of the surface of the metal in contact with HE when laser energy is incident on the opposite side of the metal. The temperature rise was measured as a function of incident laser power, spot size, metal composition and metal thickness. Numerical simulations were also performed to solve the two-dimensional heat flow problem for ... continued below

Description

Measurements have been made to determine safe levels of laser exposure on common metals used in contact with high explosive (HE) samples. Laser light is often used on metals in contact with HE during alignment procedures and experimental data collection. The measurements look at temperature rise of the surface of the metal in contact with HE when laser energy is incident on the opposite side of the metal. The temperature rise was measured as a function of incident laser power, spot size, metal composition and metal thickness. Numerical simulations were also performed to solve the two-dimensional heat flow problem for the experimental geometry. In order to allow a single numerical simulation to represent a large number of physical cases, the equations used in the simulation were expressed in terms of dimensionless variables. The normalized numerical solutions can then be compared with the various experimental configurations used. Calculations and experiment agree well over the range measured.
