Emittance Diagnostics
For space-charge dominated beams, the common quadrupole-based emittance measurement technique can be inaccurate. In this case, a set of slits can be used to measure emittance by dividing the beam into a number of spaced one-dimensional beamlets. When these beamlets are imaged downstream from the slits, the phase space can be inferred and the emittance can be calculated.
RadiaBeam offers Emittance Slits customized for your beam parameters. The slits are machined using advanced techniques to maintain a high degree of parallelism and flatness. We can provide the slits alone, to mate to your vacuum hardware, or as a complete system including cube and linear actuator.
The Emittance Slits require a beam profile imaging screen, such as our TPM System, to be used downstream.
