With the goal of understanding beam-induced cavitation damage in liquid metal targets, several experiments have been performed at Los Alamos National Laboratory's WNR facility. The most recent experiment was completed during the Summer of 2011, and consisted of 19 test cases, each with a unique combination of target configuration and beam properties. For each test case, 100 beam pulses irradiated the target with a typical repetition rate of two pulses per minute. A typical pulse contained 2.7*10¹³ protons in a pulse length of <300 ns , with a 7 by 17 mm RMS beam transverse beam size. Toroids in both air and vacuum provided the longitudinal measurements, and a luminescent screen with multiple camera systems provided the transverse measurements. Installation was completed in a few days, commissioning with beam in a few hours, and irradiation of all test targets in about one week of dedicated beam. This paper will provide an overview of the experiment, a description of the beam instrumentation systems, and a discussion of instrumentation performance. Particular attention will be payed to the challenges of rapid deployment and system robustness.
