Radiation beam alignment for a linear accelerator (LINAC) and gantry comprising steps of: For each beam alignment parameter value in a set (for example A-D): (a) With the beam alignment parameter of t

A linear accelerator. The linear accelerator may include a buncher to generate a bunched particle beam from a charged particle beam, and a plurality of acceleration stages, to accelerate the bunched particle beam. The linear accelerator may further include a phase control system, to individually measure a phase of an RF signal that is applied at a first frequency to a given acceleration stage of the plurality of acceleration stages. The phase control system may include an RF signal pickup assembly, comprising a plurality of RF signal detectors, arranged separately in the plurality of acceleration stages. The phase control system may further include a phase measurement circuit, to convert an RF pickup signal, received from an RF signal detector of the RF pickup assembly, into a digital baseband signal, for determining a phase of the RF signal.

The application provides a method for installing solenoid of an electron linear accelerator, which comprises the following steps: setting a front stand; setting a middle stand for installing at least one component of the front part in the rear section and a solenoid focusing assembly, wherein the solenoid focusing assembly is slidably arranged on the middle stand; setting a rear stand for installing an accelerating tube assembly; when replacing the solenoid, removing all the components of the front part on the middle stand and the support seat thereon, moving the solenoid focusing assembly towards the front stand to make the solenoid out of the accelerating tube; assembling a new solenoid into the solenoid focusing assembly and moving the solenoid focusing assembly towards the rear stand to make the solenoid into the accelerating tube; then, assembling the support seat on the middle stand; and installing the removed components on the middle stand and performing system collimation.
