PETRA III upgrade project

Start of construction in 2007

http://petra3.desy.deH. Franz Hangzhou 16.6.2005

Upgrade of PETRA

• New magnetic lattice in one arc (NE)

• New vacuum system for the entire ring

• New power supplies and RF system

• State of the art diagnostics and feedback system

• Upgrade of the injection system

• Replacement of damaged magnets

• Installation of damping wigglers to reduce emittance

Focus on high brilliance


Complex biomolecules

Blue Tongue Virus

Large number of close Bragg spots

Low divergence is essential

Materials science

Hard X-rays: 50-100 keV; penetration depth 5 cm in Al, 4 mm in Fe

Looking at grain statistics: Position, morphology, orientation, deformation (plastic/elastic), composition

Spacial resolution now: 1.5 x 5 x 50 µm3 at PETRA III below 1µm (2-d)

Todays powder samples will be the singlecrystals of tomorrow
