A water cooling system for linear accelerator

Abstract

The invention relates to the technical field of a temperature control technology and water cooling equipment for a linear accelerator, in particular to a water cooling system for the linear accelerator. The water cooling system for the linear accelerator is characterized by comprising a main flow loop and a water mixing loop, wherein the main flow loop comprises a refrigerating machine; output cooling water of the refrigerating machine sequentially passes through a water inlet main pipe, a first flow meter and a water-mixing tee joint to be connected with a water separator; the water separator is connected with the linear accelerator through a first water pipe group; the linear accelerator is connected with a water collector through a second water pipe group; and the water collector sequentially passes through a first tee joint, a first water return main pipe, a second tee joint and a second water return main pipe to be connected with the refrigerating machine. By adopting a method for mixing one part of high-temperature return water flowing out from an outlet of a heat exchange runner of the accelerator into the cooling water, the problem of hysteresis in the dynamic adjustment process of the refrigerating machine can be solved and accurate temperature control on the linear accelerator is achieved.

Description

technical field [0001] The invention relates to the technical field of temperature control technology and water cooling equipment of a linear accelerator, in particular to a water cooling system for a linear accelerator. Background technique [0002] Accelerator is a device that increases the kinetic energy of charged particles, which can be used in nuclear experiments, radiological medicine, radiochemical, radioactive isotope manufacturing, non-destructive flaw detection, etc. The British scientist G. Ising proposed the initial concept of the linear accelerator in 1924, and the German scientist Rolf Wideroe gave a practical linear accelerator design in 1928. The drift tube of the accelerator is alternately connected to high-frequency power and grounded. However, the length of the drift tube needs to grow as the particle speed increases to ensure that the particles reach the gap at the correct time each time and are accelerated. When the particle velocity is high, a higher ...

Problems solved by technology

Linear accelerators are mostly built in enclosed spaces with radiation protection. Considering factors such as safe maintenance, space saving, and convenient operation, the refrigerator of the linear accelerator water cooling system must be installed outside the enclosed space, between the cooled accelerator cavity. There is a certain distance between the pipes, which makes the dynamic adjustment of the refrigerator to the temperature control object have a certain hysteresis, which seriously affects the temperature control accuracy.
