Accelerator-Division at DESY
The accelerator division (M-Division) fulfils an essential obligation of the charter of DESY:
Design, construction and operation of particle accelerators for research with synchrotron radiation.
The bright curved building in the lower left is the new PETRA III experimental hall.
The FLASH experimental hall is the smaller building on the bottom almost in the middle. The FLASH tunnel housing the cryomodules of the superconducting accelerator and the undulators extends from the building in the middle of the picture to the experimental hall.
The large hall in the upper right is the cryogenic plant with the He storage tanks.
