Accelerator instrumentation and diagnostics research specialises in the development of devices to measure the position, charge, length, energy, polarisation of high energy beams.

Laserwire Diagnostics
A laserwire is a minimally invasive diagnostic tool measure beam profiles. For high charge density machines, conventional diagnostic methods become prohibitive due to the mutual destruction of the beam and tool. A laserwire uses a narrowly focused laser, orthogonally aligned to the accelerator beam, similar to a wire scanner. Two common interactions are used for laserwire interactions; inverse-Compton scattering, and photodetachment.
The laserwire projects at Royal Holloway include implementation at:
- ATF2 at KEK
- PETRA3 at DESY
- LINAC4 at CERN
- FETS at RAL.
