Target Division

Target Division

Spallation sources are devices designed to produce neutrons using reactions with the same name. To produce spallation reactions, it is necessary to accelerate a proton through a series of electromagnetic fields in the accelerator until it acquires a high level of kinetic energy. At that moment, it is made to collide with the atom of a heavy material (normally mercury, lead or tungsten) to bring about the nuclear reaction which…

PBIP

Proton beam has to travel trough more than 500m of acceleration devices before impinging the target, what makes necessary to prepare several checking systems to control the beam quality. The PBIP (Proton Beam Instrumentation Plug) consists of multiple components introduced in the protons' path, being their functions to measure several properties to determine that protons arriving to the target do it with the proper shape, energy, frequency, etc., and also…

PBW

The PBW (Proton Beam Window) is the device in charge to separate the ultra-high vacuum atmosphere of the accelerator, to the rough vacuum atmosphere present at target side. A thorough design permits a 5MW proton beam to cross two thin plates of less than 1.25mm without suffering more than 1% of scattering (perturbation of beam features). Nuclear calculations have been applied to study the material, its lifetime and property changes,…
