Recurrent novae occurring in symbiotic binaries are candidate sources of high energy photons, reaching GeV energies. Such emission is a consequence of particle acceleration leading to pion production. the shock between matter ejected by the white dwarf, undergoing a nova explosion, and the wind from the red giant companion are responsible for such a process, which mimics a supernova remnant but with much smaller energetic output and much shorter time scales. Inverse Compton can also be responsible for high energy emission. Recent examples are V407 Cyg, detected by Fermi, and RS Oph, which unfortunately exploded in 2006, before Fermi was launched.

conventional x-ray technology, that we term line focus x-ray tube (LFXT). In LFXTs an electron beam is
focused to an extremely thin focal spot on a rapidly rotating tungsten target. A change in the mechanisms of
target heating allows very high electron beam currents without melting the target material. In terms of photon
flux and coherence length, the performance of the line focus x-ray tube compares with inverseCompton
scattering sources. Moreover, the LFXT is capable of producing dose rates of up to
constant in time.
Problem 2.1. (Compton scattering.) A photon of wavelength A. hits a
stationary electron (mass me) and comes off with wavelength A.' at an
angle (). Derive the expression
A.'-A. = (h/me)(l-cos()).
(a) When a photon scatters off a charged particle which is moving with
a speed very nearly that of light, the photon is said to have undergone an
inverseCompton scattering. Consider an inverseCompton scattering in
which a charged particle of rest mass m and total mass-energy (as seen
higher for the high-
Z material, for which electron binding to the atoms is more significant.
10.3 InverseCompton sources
In the previous section we considered the electron to be at rest, which is a reasonable
approximation for electrons in a solid in a laboratory frame. In that case, the incom-
ing photon imparts energy to the electron. However, if the electron is initially at high
velocity, it can lose energy, and the output photon energy can be higher than the input.
This phenomenon is known as inverseCompton scattering, and it can be used to con-
