Individual solid targets will be mounted on a vertical ladder assembly that will be retracted into an inverted hat which will protrude through a hole in a flange in the base of the target chamber.The inverted hat will contain the vertical ladder, solid target cooling tubes, and drive assembly for the ladder as shown in figure2.3.2.1. When the cryotarget is retracted into its highest position, the distance between the beam position and the bottom of the cryoloop is expected to be about 20 cm (8 in) This is sufficient space to permit vertical mounting of 7 target foils on frames that are centered 1 in apart. Two types of target ladders and frames are currently available. One target ladder contains provision for water cooling. The second type of ladder and target frame does not have water cooling and was used during the first commissioning runs with low beam currents (A). The dimensions of the target ladder and target frame are shown in figures2.3.2.2 and 2.3.2.3 The targets mounted on the ladder are selected remotely and the orientation angle of the target normal with respect to the incident beam direction is also set remotely.
