Non-interceptive Beam Diagnostics in a H− Linac During Operations Using Laser Comb and Virtual Slit | |
|
||
| Several novel techniques have been recently developed for laser wire based non-interceptive H− beam diagnostics. A laser comb ¿ ultrashort laser pulses with macropulse structure ¿ was implemented and used for measuring time-resolved profiles/emittances from a single scan. A virtual slit technique was demonstrated for the precise measurement of short bunches formed in the superconducting linac. Both techniques have been applied to measuring parameters of neutron production H− beam at the linac of the Spallation Neutron Source. Key components in the implementation and operation of the laser comb and virtual slit will be described. Applications of the measurement results to the accelerator physics study will also be discussed. | ||
