  The East Area at the Proton Synchrotron is one of CERN's longest running facilities for experiments, beam tests, and irradiations with a successful history of over 55 years. The facility serves more than 20 user teams for about 200 days of running each year and offers mixed secondary hadron, electron and muon beams of 0.5 GeV/c to 10 GeV/c. In addition, the primary proton beam or ion beam is transported to the irradiation facilities CHARM and IRRAD. Due to the steadily high user demand, the CERN management approved an upgrade and renovation of the facility to meet future beam test and physics requirements. New beam optics will assure a better transmission and purity of the secondary beams, now also with the possibility of highly pure electron, hadron or muon beams. The upgrade includes a pulsed powering scheme with energy recovering power supplies and new magnets, reducing both power and cooling requirements. Together with the building consolidation, this results in a considerably lower energy consumption. The renovation phase is scheduled during the technical stops between 2018 and 2020. We will give an overview of the project scope including upgrades and future beams.

MOMENT (MuOn-decay MEdium baseline NeuTrino beam facility) is an accelerator-based neutrino beam facility using neutrino from muon decays. The proton driver is a continuous-wave proton linac of 1.5 GeV and 10 mA, which means an extremely high beam power of 15 MW. After bombarding the target, the abandoned proton beam power is very high and should be separate from target station carefully. Because of the energy is not very high and the layout of following transport line isn't linear, we should design special separation line for high momentum proton beam. In this paper the design of separation scheme at MOMENT will be proposed and discussed.
