+ | * Each cup is contolled by one of the push buttons in the photo. | ||
+ | - The name of the cup operated by the button is always illuminated. | ||
+ | - When the cup is in, the red "in" light in the button is illuminated. | ||
+ | - When the cup is out, the green "out" light in the button is illuminated. | ||
+ | - Each time a button is pushed the cup will change to the other state, in or out. | ||
+ | |||
+ | |||
+ | * Placing the LE cup in the "out" position will sound an audible and visual warning throughout the facility. | ||
+ | * When the HIGH RAD MODE key switch is in the "ON" position there will be a 15 second delay between pushing the LE cup "out" button and: | ||
+ | - The cup lifting out of the beam path | ||
+ | - The green "out" light on the button illuminating | ||
+ | |||
+ | * We have 4 Faraday Cups for beam current optimization at critical points along the beam path. | ||
+ | - LE: Located after the Buncher Tubes and before the LE XY steerer. | ||
+ | - HE: Located at the exit of the Accelerator before Quad 1. | ||
+ | - Analyzer: Located after the Image Slits and before the Beam Pick Off. | ||
+ | - Swinger: Located under the steps, after the Analyzer and before Swinger Magnet 1. | ||
