The LEIR Accelerator
Basic Geometry
The position and the basic shape of LEIR is fixed by the fact that LEIR recycles the LEAR (Low Energy Accumulating Ring) bending blocks at their original position
It has an almost “square” geometry, ~ 80 m in circumference, with four bending sections, each one deflecting the beam by 90° and four straight sections, each one with a total length of about 12.8 m
LEIR Components
The four section of LEIR are composed of:
4 Main bending magnets
4 Triplets
4 Trim Quadrupoles
4 Doublets
8 Chromatic Sextupoles
2 Harmonic Sextupoles
3 Extraction Kickers
1 Electrostatic and 2 Magnetostatic Septa Magnets
An Electron Cooler
2 Finemet RF cavaties (Of which one cavity is used as spare, alternating each year)
LEIR Instrumentation
Several instrumentation devices, including :
4 Schottky,
16 BPM,
2 IPMs,
1 Beam Screen (BTV)
2 Beam Current Transformer (BCT)
1 Wide band transverse feed back
LEIR Operational Cycle: 1 Injection
LEIR Operational Cycle: 7 Injections
