I attached an aluminum wire screen to the back of the AOM Amplifier 2U Chassis to (hopefully) prevent RF radiation from going around the lab but allowing for airflow to cool the amplifiers. I needed to cut the chicken wire to allow for the #4-40 screws to go thorugh. I also needed some 0.281" outer diameter washers to hold the chicken wire since the screw head diameter went through the (cut) chicken wire. The wavelength of 200 MHz light is 1.5 m, so this chicken wire should be sufficiently dense to contain most of the RF output. See attached photo.
