are finding an increasing utility in particular with the trend of numerous light sources pushing to lower emittances and thus higher intra-beam scattering, while operating in top- up injection modes and employing in-vacuum undulators in their rings. the development of an optimized electron beamloss monitor...
from the cathode. a device employing this latter method is known as a cold cathode device. in high voltage switching the presence of high voltages, and hence the possibility of large voltage gradients within devices means that the cold cathode system, quite a rarity in most other types of tubes, is...
