“…II A recent idea to measure range 278 is to use the acoustic pulse generated by particles traversing a medium. 279 By using a pulsed particle beam and knowing the speed of sound, the location of the sound pulse can be determined by measuring the propagation time. The intensity of the acoustic pulse is shown to be proportional to absorbed dose, and therefore the detected acoustic pulse has the same shape as the depth-dose distribution.…”

Clinical trials using accelerated heavy charged-particle beams for treating cancer and other diseases have been performed for nearly four decades. Recently there have been worldwide efforts to construct hospital-based medically dedicated proton or light-ion accelerator facilities. To make such accelerated heavy charged-particle beams clinically useful, specialized instruments must be developed to modify the physical characteristics of the particle beams in order to optimize their biological and clinical effects. This article reviews the beam modifying devices and associated dosimetric equipment developed specifically for controlling and monitoring the clinical beams.

“…The acoustic signals of particle interactions in water have been studied through extensive and detailed simulations, which have been validated by experimental measurements using particle and laser beams [5,6]. The acoustic signal expected expected for a 1 EeV neutrino interaction at a 1 km distance from the sensor is shown in Fig.…”

Abstract. Cosmic neutrinos with ultra high energies can be detected acoustically using hydrophones. The detection of these neutrinos may provide crucial information about then GZK mechanism. The flux of these neutrinos, however, is expected to be low, so that a detection volume is required more than a order of magnitude larger than what has presently been realized. With a large detection volume and a large number of hydrophones, there is a need for technology that is cheap and easy to deploy. Fiber optics provide a natural way for distributed sensing. In addition, a sensor has been designed and manufactured that can be produced cost-effectively on an industrial scale. Sensitivity measurements show that the sensor is able to reach the required sea-state zero level. For a proper interpretation of the expected bipolar signals, filtering techniques should be applied to remove the effects of the unwanted resonance peaks.

“…Theoretical models [2] and experimental measurements [3] show that the signature of this event is a single bipolar pulse, with acoustic energy concentrated around 10 kHz. Noise conditions measured by SAUND II have been studied in detail [4].…”

“…In the last decade, feasibility studies for acoustic UHE neutrino detectors have been initiated in large natural bodies of water, ice and salt. The advantage to this technique is the possibility of building very large arrays (thousands of km 3 ) with sparse microphones, thanks to the large attenuation length of sound at the appropriate frequencies in these media. The Study of Acoustic Ultra-high Energy Neutrino Detection (SAUND) phase II is the first experiment to read out hydrophones undersea for the purpose of detecting UHE neutrinos using such an expansive array (∼1500 km 3 ), and follows the first phase [1] where ∼15 km 3 were read out at the same site.…”

Search for acoustic signals from ultrahigh energy neutrinos in1500 km3of sea water

An underwater acoustic sensor array spanning ∼1500 km 3 is used to search for cosmic-ray neutrinos of ultra-high energies (UHE, Eν>10 18 eV). Approximately 328 million triggers accumulated over an integrated 130 days of data taking are analysed. The sensitivity of the experiment is determined from a Monte Carlo simulation of the array using recorded noise conditions and expected waveforms. Two events are found to have properties compatible with showers in the energy range 10 24 eV
