Summary
| Description |
Deutsch: DESY, Hamburg; Supraleitende Kavität zur Beschleunigung von Elektronen und Positronen; Länge der Struktur ca. 1m; Hergestellt aus hochreinem Niob.
Im Inneren der Kavität beschleunigen die elektrischen Felder von stehenden elektromagnetischen Wellen die geladenen Teilchen. Der Resonator wurde aus hochreinem Niob gebaut und ist für eine Resonanzfrequenz von 1,3 GHz ausgelegt. Der Resonator besteht aus neun elliptisch geformten Zellen (Rotationsellipsoiden). Die Länge einer einzelnen Zelle ist so gewählt, dass sich das elektrische Feld der Welle gerade umkehrt, wenn ein Teilchen in die nächste Zelle eintritt. Damit wird eine kontinuierliche Beschleunigung gewährleistet.
English: DESY, Hamburg; Superconducting cavity for accelerating electrons and positrons; length of the structure about 1m; Manufactured from high purity niobium.
Inside the cavity, the electric fields from standing electromagnetic waves accelerate the charged particles. The resonator was built from high-purity niobium and is designed for a resonance frequency of 1.3 GHz. The resonator consists of nine elliptically shaped cells (ellipsoids of revolution). The length of a single cell is chosen so that the electric field of the wave is about to reverse when a particle enters the next cell. This ensures continuous acceleration. At typical operating temperatures of around 2K, the niobium cavity is superconductive and requires less energy to operate than conventional copper cavities.
