Accelerator energy storage ring

What are electron positron storage rings used for?

Electron positron storage rings are used primarily for subatomic particle research in particle accelerators. When a single storage ring is used, the energies of the two beams are always the same. Due to the pulsed operation of the acceleration system, the particles are stored in bunches, which can collide at only a few places around the ring.

What is a particle accelerator?

A particle accelerator is a device for accelerating particles to high speeds. Although particles are sometimes accelerated in storage rings, the main purpose of these rings is to make possible energetic interactions between beams of particles moving in opposite directions.

What is the Intersecting Storage Rings (ISR)?

The Intersecting Storage Rings is a former particle accelerator at CERN. It was the world's first hadron collider On 27 January 1971, two beams of protons collided in the Intersecting Storage Rings (ISR) for the first time.

What is a storage ring?

Storage rings of the charged particles are the backbone of the high energy circular colliders such as the Large Hadron Collider (LHC), where the Higgs particle was discovered in Geneva, Switzerland. They are also essential parts of the modern synchrotron light sources for research of material and medical sciences.

How does a storage ring work?

Storage ring/bending magnets After leaving DESY II, the electron bunches then enter the storage ring PETRA III (before the former storage ring DORIS III), where all the actual research happens. To allow the electrons to circle the ring for many hours, they travel in a metal tube in which an ultra-high vacuum is maintained, the vacuum chamber.

How are particles stored in a ring?

In a particle accelerator, particles are stored in bunches and are made to collide at only a few places around the storage ring. Detectors surround these collision points to record the particles produced when an electron and a positron annihilate.
