  7. Abstract:
  8. In this thesis, the accelerator and cooling equations have been investigated in order to improve the quality of the accelerator by using cooling. With the help of MATLAB software, a cooling method has been proposed that can have a relatively uniform temperature throughout the accelerator. In order to optimize and minimize the number of coolers for each desired temperature difference and each number of coolers, an arrangement of coolers is found so that the temperature difference is minimal. There are different types of charged particle accelerator systems in terms of the structure and energy of the output particles. Linear accelerators are accelerators in which charged particles move along a straight line by an electric field. Linear accelerators accelerate particles using radio frequency fields. Attenuation in waveguides plays an important role in accelerator performance. If we have a certain amount of energy density in a short part of the loaded waveguide, due to resistance losses in the walls, we will have an energy flow to the waveguide walls. This energy loss can be called the waveguide Q, which is characteristically called the quality factor. To increase the quality factor, it is enough to reduce the power loss from the walls. One of the ways to reduce the power dissipation of the walls is the use of a cooling system. In this thesis, in order to improve the cooling system, several coolers are used so that the placement of each cooler helps to even out the temperature. In addition to the arrangement of the coolers, the parameters related to the coolers are checked to make the temperature more uniform
