First Time

The possibility of performing proton radiography by using the proton angular spread due to Coulomb multiple scattering was investigated, for the first time, with an emulsion film detector. Two different phantoms were irradiated with the therapeutic proton beam at the Paul Scherrer Institut (PSI) in Villigen, Switzerland. The first one is a simple polymethylmethacrylate (PMMA) block having two different thicknesses (4 cm and 3 cm), and the second one is a PMMA cube with five aluminum rods embedded along a diagonal. Only one emulsion film was needed to perform the radiography, an important issue as the analysis of this kind of detector is time-consuming. Furthermore, the method showed an enhanced contrast when high atomic-number materials are traversed. This gives an advantage, when compared to proton range radiography.

Multiple Coulomb Scattering

An analytical solution of the angular problem to the approximation of middle angles which is valid for any angles of particle deviation in an elementary event of Coulomb scattering has been obtained using the approximate operator (Vaskin et al. 1966). The proposed method makes it possible to evaluate the accuracy of the resulting expressions and the contribution from non-multiple and multiple Coulomb scattering.

Multiple Coulomb Scattering

Particles are sensed through their interactions with matter. To begin with, the chapter introduces the terms cross section and absorption. Then successively the most important interactions that are employed for the detection of the various particle types are discussed: energy loss of charged particles by ionisation and bremsstrahlung, multiple Coulomb scattering of charged particles, interactions of photons and hadrons with matter. The interactions leading to the development of electromagnetic and hadronic showers are treated in more detail in chapter 15 (Calorimeters), while energy loss by Cherenkov and transition radiation are discussed in chapters 11 and 12, respectively. When describing the interaction processes an attempt is made to address the theoretical background in a way that the derivations ought to be comprehensible.

Charge Resolution

We are reporting here on the results obtained from a balloon exposure of a cosmic ray detector flown in 1977. This detector, described elsewhere, Gilman and Waddington (1975), Young (1979), measures elemental charge from scintillation and Cherenkov signals and mass from Cherenkov and total energy determined from a measure of residual range in nuclear emulsion. The charge resolution obtained ranged from 0.19 to 0.21 charge units between neon and nickel. This resolution was sufficient to ensure that all but a few percent of the nuclei were correctly identified, even for those elements of low abundance that have neighbors with high abundances, such as Cl or Al. The mass resolution obtained for those nuclei that stopped in the emulsions ranged from 0.40 to 0.70 amu for A between 20 and 60 amu. This was not adequate to uniquely resolve neighboring mass peaks in many cases, but was adequate to draw a number of conclusions regarding many of the more abundant elements.

Data on near-horizontal muons obtained with experimental complex NEVOD-DECOR are analyzed. More than 1.5 × 103 atmospheric muons scattered into upper hemisphere with energy above 7 GeV were registered. Calculations show that the main process forming albedo muon flux near horizon is multiple Coulomb scattering.
