\def\Goals{
In tokamak GOLEM, there is a scintillation counter installed to detect hard x-rays. Gamma rays with a wavelength in the 
range from 0.1 nm to 0.01 nm are detected, this corresponds to energies from 12 keV to 120 keV. The goal is to detect electrons with high energy.}

\def\Theory{
Each electron is affected by the electric field and by collisions. The force of the electric field accelerates the electrons, whereas 
the friction force decelerates them. When the force of the electric field tops the friction force, the electron is accelerated. The cross 
section of collisions falls and the electron achieves almost a speed of light. As the electron is accelerated the radius of its trajectory 
increases.
The electron emits photons due to synchrotron radiation, bremsstrahlung, collisions with the vessel (most electrons hit the limiter)
The lower energy bounds of HXR can be used for detection of high-Z materials. Lines of heavy impurities in the H-like ionization 
state produce distinct peaks in the x-ray spectrum at given energies.}
