The invention provides a 4 kHz repetition rate argon fluoride excimer laser system for producing an UV wavelength 193 nm output. Interference scenarios may be avoided by predicatively determining the potential for interference between the channels of multiple communications on the dual-technology wireless communication devices. The container, such as a dump truck bed or a dump body, includes a central leak-proof top-loading door; a rear tailgate for dumping the contents from the rear of the container; recessed framework having upper margins of the container walls and a door-jamb that define a reservoir; and a plurality of brace members for supporting the frame against the walls of the container.
