Our Facilities
The table below lists the current facilities for an at-a-glance comparison of beam parameters and capabilities.
Note: these comparison tables are large and are not designed for mobile view.
Facility comparison tables below:
1. Particle Beam Parameters
Note that beam parameters at accelerator facilities are often correlated. For example, a higher bunch charge may mean a larger spot size. Not all parameters are therefore available at once. However these values will give you a good indication of what beam can be expected.
