Abstract
A method for recovering energy from spent energy recovered linac (ERL) beams. The method includes adding a plurality of passive decelerating cavities at the beam dump of the ERL, adding one or more coupling waveguides between the passive decelerating cavities, setting an adequate external Q (Qext) to adjust to the beam loading situation, and extracting the RF energy through the coupling waveguides.
Claims1
A method for recovering energy from a spent energy recovery linac (ERL) having an electron beam, comprising:
- an electron gun injecting electrons to form the electron beam;
- a linear accelerator (linac) accelerating the electron beam;
- adding a booster at the exit of the electron gun to provide radio frequency (RF) power for accelerating the electrons exiting the electron gun;
- a spent beam directing a portion of the electron beam to a beam dump;
- adding one or more passive decelerating cavities to the spent beam leading to the beam dump;
- adding one or more coupling waveguides between the passive decelerating cavities;
- setting the external quality factor (Qext) of the coupling waveguides to the beam load;
- extracting the RF energy through the coupling waveguides;
- and
- returning the extracted RF energy to the booster.
