The Proton Synchrotron (PS, sometimes also referred to as CPS [1]) is a particle accelerator at CERN. It is CERN's first synchrotron, beginning its operation in 1959. For a brief period the PS was the world's highest energy particle accelerator.

PS and SPS Weekly User Meetings - if not announced otherwise - take place on Thursdays at 10:30 AM in room 874/1-011 (CERN) in person. Attendance is mandatory one week prior to the scheduled run, during the beam time and for one meeting after the beam time.

The Proton Synchrotron (PS) is a key component in CERN’s accelerator complex, where it usually accelerates either protons delivered by the Proton Synchrotron Booster or heavy ions from the Low Energy Ion Ring (LEIR). In the course of its history, it has juggled many different kinds of particles, feeding them directly to experiments or to more powerful accelerators.

The Proton Synchrotron Booster (PSB) is the first and smallest circular proton accelerator (a synchrotron) in the accelerator chain at the CERN injection complex, which also provides beams to the Large Hadron Collider. [1] .

Mar 14, 2025 · At CERN, beams of particles are accelerated faster and faster, just like a relay race (where each runner is faster than the previous one). The LHC’s relay team has five runners, in order of appearance: Linear Accelerator 4 (Linac4), the Proton Synchrotron Booster (PSB), the Proton Synchrotron (PS), the Super Proton Synchrotron (SPS) …

Jan 27, 2004 · The Proton Synchrotron (PS) is a key component in CERN’s accelerator complex, where it accelerates protons delivered by the PS Booster or heavy ions from the Low Energy Ion Ring. In the course of its history it has juggled with many different kinds of particles, feeding them directly to experiments or to more powerful accelerators.

Feb 29, 2024 · Even today, 65 years later, the PS is the heart of CERN’s accelerator chain. And while the machine has of course undergone many phases of improvement, its fundamental structure has remained unchanged.

The Proton Synchrotron (PS) accelerated protons for the first time on 24 November 1959, becoming for a brief period the world’s highest energy particle accelerator. With a beam energy of 28 GeV, the PS became host to CERN’s particle physics programme, and provides beams for experiments to this day.

The Proton Synchrotron (PS) is a key component in CERN’s accelerator complex, where it usually accelerates either protons delivered by the Proton Synchrotron Booster or heavy ions from the Low Energy Ion Ring (LEIR).

From 1978 until 2018, the Booster received protons from Linac2 at 50 MeV and accelerated them to 1.4 GeV for injection into the PS. The Booster allows the PS to accept over 100 times more protons, which greatly enhances the beam's use for experiments.
