Beam Diagnostics and Applications

Particle beams in accelerators are detected through the electromagnetic elds they create. Position and intensity monitors are based on the near eld which stays attached to the charges. A large variety of measurements can be carried out with these devices. The closed orbit is obtained by reading out the position averaged over many turns. Change in the orbit resulting from a controlled de ection ...

Short Bunch Beam Diagnostics

With the emergence of 4th generation FEL based light sources there is now considerable interest in both producing and characterizing ultra-short (<100 fs) electron bunches. Knowledge of the extremely high peak current in a short bunch is required to diagnose the SASE (self amplified stimulated emission) process. Measuring the femtosecond duration of the pulse is inherently interesting, particul...

Beam-beam Diagnostics from Closed-orbit Distortion

We study the applicability of beam-beam deflection techniques as a tuning tool for asymmetric B factories, focusing on PEP-II as an example. Assuming that the closed orbits of the two beams are separated vertically at the interaction point by a local orbit bump that is nominally closed, we calculate the residual beam orbit distortions due to the beam-beam interaction. Difference orbit measureme...

Accelerator Optimization through Beam Diagnostics

A comprehensive set of beam diagnostics is key to the successful operation and optimization of essentially any accelerator. The oPAC project received 6 M€ of funding within the EU's 7th Framework Programme. This has allowed to successfully train 23 Fellows since 2011. The network joins more than 40 institutions from all around the world, including research centers, universities and private comp...
