CDS 7
New CDS cavity RF gun has single standing wave cavity.
This cavity is used for cathode fix structure test or 0 deg injection.
Required RF power is low, conditioning will be quickly.

4. Acceleration cavity
This cavity is also annual coupling.

5. Reduce multipactoring choke structure design
weak field
good vacuum conduction
ABS E
ABS B

6. This gun is able to test with 60 deg or 0 deg laser injection
Cathode diameter is 6 mm
Aperture is 8 mm

7. In the simulation, 5 nC beam generation is possible

8. Cavity cells is under manufacturing.
