Positron BeamsTwo-Photon ExchangePrecision Form FactorsThe proton elastic form factor ratio can be measured either via Rosenbluth separation in an unpolarized beam and target experiment, or via the use of polarization degrees of freedom. However, data produced by these two approaches show a ...
where a and g are functions only of the scalar r, and the symmetry axis is fixed as the line passing through the two charges. Let us subject (22) to Eq. (8) and ∇×E(1)=0. The relation a(r)=1rddrg(r), (23) provided that the vectors r,R are not parallel. We shall...

al.22in a collisionless plasma consisting of warm ions, hot isothermal electrons and a cold relativistic electron beam. Properties of ion- and electron-acoustic solitons have been investigated by Lakhina et al.23in an unmagnetized multi-component plasma in the presence of ion and electron beams b...
theoretical analysis of the charge-deposition density in single slabs located in vacuum (Alouani-Bibi et al., 1999. Can. J. Phys. 77(2), 127–136), a semi-empirical model that describes the charge-deposition distributions in two-layer systems irradiated by fast electron beams has been ...
The OLYMPUS experiment was carried out at DESY Hamburg, Germany using 2.01 GeV electron and positron beams of the DORIS storage ring incident on an internal hydrogen gas target. Multiple independent luminosity monitors were operated in parallel to the main spectrometer during data taking to allow ...

“central point”. As the brush moves, both the central point and all of the star lines through it are processed. The simplest design is to have a set of fixed, intersecting beams and move them from point to point within the patient, perhaps turning them on and off as we go. This ...
Transverse as well as longitudinal polarizations of the electron and positron beams are taken into account. We show how these model-independent distributions can be used to deduce some general properties of the nature of the interaction. We then specialize to two specific two-particle final states...
In this work, we show that there are significant benefits to combining the Super-Rosenbluth technique with positron beam measurements. In addition to providing improved precision and a greater kinematic reach, the use of the Super-Rosenbluth technique provides a comparison of e$^+$ and e$^-$ ...
