JEEP is a multi-purpose, high energy X-ray beamline providing flexibility in the type and complexity of the experiments it can accommodate.
The beamline has two in-line experimental hutches.
The first Experimental Hutch (EH1) is in the main Diamond Experimental Hall. Its proximity to the storage ring provides a very high intensity beam for diffraction and imaging experiments. EH1 took it's first users in October 2009.
A second Experimental Hutch (EH2) is in an external building outside the main Experimental Hall. It provides a space for large-scale engineering and processing experiments. These include ground breaking experiments to simulate the service conditions experienced by real engineering components while their internal stress state and structures are continually monitored by the X-ray beam. Experimental Hutch 2 also provides space to set up complex or long-duration experiments, while allowing other experiments to continue in Experimental Hutch 1. EH2 took it's first users in July 2011.
High density materials, such as metals, are perfectly suited for analysis on I12.

The beamline is also capable of delivering a high flux of white beam and monochromatic beam for diffraction and imaging experiments.
