Abstract

The 5 MW proton beam to be delivered to the ESS spallation target must be tuned to its nominal value and controlled at all times. To achieve this, a suite of beam diagnostics has been proposed and is currently been designed. It is located in two plugs, the Proton Beam Window (PBW) plug and the Proton Beam Instrumentation Plug (PBIP). Here we present the design concept for the PBIP imposed by the beam physics requirements as well as by the high power target environment, i.e. material lifetime, remote handling and waste management.

Highlights

The ESS accelerator delivers to the target a 125 MW peak power, 2.86 ms pulsed proton beam with a low emittance of 1 mm mrad
The required beam control is enabled by a suite of diagnostics, located mainly in the target area[3], and composed of two imaging systems, one multi-wire grid and three aperture monitoring systems
The two imaging systems are both supported by the Proton Beam Instrumentation Plug (PBIP) and they provide images of the beam intersecting the Proton Beam Window (PBW) at the entrance of the target monolith area and the target wheel
