	The Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) is a proof-of-principle R&D experiment at CERN. It is the world’s first proton driven plasma wakefield acceleration experiment, using a high-energy proton bunch to drive a plasma wakefield for electron beam acceleration. The AWAKE experiment will be installed in the former CNGS facility and uses the 400 GeV proton beam bunches from the SPS, which will be sent to a plasma source. An electron beam will be injected into the plasma cell to probe the accelerating wakefield. Challenging modifications in the area and new installations are required for AWAKE. First proton beam to the experiment is expected late 2016. The accelerating electron physics will start late 2017. This paper gives an overview of the project from a physics and engineering point of view, it describes the main activities, the milestones, the organizational set-up for the project management and coordination.

The CERN Super Proton Synchrotron (SPS) presently uses an internal beam dump system with two separate blocks to cleanly dispose of low and high energy beams. In view of the increased beam power and brightness needed for the LHC Injector Upgrade project for High Luminosity LHC (HL-LHC), the performance of this internal beam dump system has been reviewed for future operation. Different possible upgrades of the beam dumping system have been investigated. The initially considered solution for the SPS Beam Dump System is to design a new, dedicated external system, with a dump block in a shielded cavern separated from the machine ring. Unfortunately this solution is not feasible with the present technology.
