Cerenkov energy loss of muons in water

Abstract

Using a large directional water Cerenkov counter and a near horizontal magnetic spectrograph, the Cerenkov energy loss of relativistic muons has been studied. The experimental results, which cover the range of muon momentum 0.3-120 GeV/C, are consistent wit$ the classical theory of Frank and Tamm. They do not indicate a decrease in the Cerenkov loss, as expected according to Tsytovitch, nor do they confirm the large rise reported by Bassi et al.

“…Given the typical energy losses of muons in water for high energy muons [12], (dE/dx) µ ≃ 2 MeV cm −1 , a vertical and central muon deposits ∼ 240 MeV in a detector with 1.2 m depth of water. At the operating gain of the SD detector, the correspondence between the amplitude of the pulse in FADC counts and the energy deposited by a particle in the detector is 1 FADC ≃ 5 MeV.…”

A new method on diagnostics of muons produced by a short pulse laser

“…Although there were lots of muon detectors since its discovery [24][25][26][27] , such as Cerenkov Detector, Drift Chamber, Time Projection Chamber, Multiwire Proportional Chamber, Resistive Plate Chamber and so on, all of the detectors are designed for a single muon event, not suitable for high-intensity measurement. Besides, these kinds of detectors generally need a complex magnet system, gas system and electronics readout system, and are thus very expensive.…”
