Question

6.
Describe the construction and working of a (i) drift tube
(ii) travelling wave in linear accelerator. What are the
advantages of linear accelerator over circular accelerators ?​

Answer 1

Answer:

LINAC is consists of several coaxially arranged hollow conductive cylindrical tubes called drift tubes. These tubes are arranged (in increasing length) in the evacuated tube. The odd tubes are connected to one terminal of Radio Frequency Oscillator (R. F.

2 Although linear accelerators cannot achieve beam, output energy as high as circular accelerators, the following advantages dictate their use in a variety of applications: (1) the open geometry makes it easier to inject and extract beams; (2) high-flux beams can be transported because of the increased options for beam ...
