Experimental setup. (a) Photo of the experimental setup, consisting of an irradiating nozzle, a target, and two CeBr\(_3\) detectors. (b) Photo of a similar setup with the target placed behind two flasks of water in the beam path. (c) That with two flasks of water placed on each side of the target. Two tungsten collimators were placed in front of each detector in the beam direction. (d) Photo of the same setup with the target of a prostate phantom with a commercial silicone insert.
