DEFINITION

Classification: 315/5.51

(under subclass 5) Subject matter wherein the hollow device has a plurality of gaps displaced along the path of the ray, each gap providing an interaction between the ray and the interior of the device.

(1) Note. Usually the gaps are formed by a drift tube between the gaps and by reentrant portions surrounding the ray between the gaps and the walls of the device.

5.44+, for plural hollow distributed parameter devices with the ray passing through each device and feedback coupling between the devices.

5.52, for a hollow distributed parameter device with the ray passing through or in and having a reentract portion surrounding the ray.
