Abstract
A photoinjector system containing modularly-structured waveguide-mode launcher, which is reversibly connected to the RF gun (containing a tubular construction formed with disattachably-affixed to one another structurally-complementary halves); and a solenoid magnet in operation enclosing such tubular structure in a central hollow. The resulting quality, power, and frequency rate of operation as well as cost of manufacturing and operation of the system are superior as compared with those of a related art system.
Claims15
A photoinjector comprising:
- a solenoid magnet unit having a central opening;
- an RF gun having first and second ends and including a cathode assembly at the first end, said RF gun being dimensioned to be removably inserted in said central opening to be positioned at a chosen location at which, in operation of the photoinjector, a magnetic field is zero;
- and
- a mode launcher reversibly attachable to the RF gun at the second end to remain outside of said central opening.
A method for fabricating a photoinjector, the method comprising:
- reversibly joining first and second halves of an RF gun of the photoinjector, said first and second halves being structurally-complementary to one another;
- reversibly affixing a mode launcher unit of the photoinjector to an end of said RF gun;
- and
- inserting the RF gun into a hollow of a solenoid magnet of the photoinjector to position said RF gun at a chosen location, wherein the chosen location is characterized by a substantially zero magnetic field during the operation of the photoinjector.
