The compensating magnet for the Zeus detector

Abstract

A bath cooled superconducting solenoid with a 280 mm in diameter warm bore, a coil length of 1200 mm and a central field of 5 T at the rated current of 950 A, was built at Ansaldo ABB Componenti. It will operate as compensating coil inside the Zeus Detector at HERA, Desy. The coil is shielded by a 3.5 tons low carbon steel cold yoke and the cold helium chamber was designed to withstand a max pressure of 20 bar. The main results obtained during the cool down and energization are reported.

Magnetically amplified light-shining-through-walls via virtual minicharged particles

“…As a suitable magnet we have identified a presently unused ZEUS compensation solenoid [78] available at DESY. It features a bore of 0.28m diameter and 1.20m length and provides a field strength of B = 5T.…”

“…The ideal magnet in this tunneling experiment with virtual minicharged particles is presumably a solenoid or Helmholtz coil magnet 2 . As a suitable magnet we have identified a presently unused ZEUS compensation solenoid [78] available at DESY. It features a bore of 0.28m diameter and 1.20m length and provides a field strength of B = 5T.…”

Magnetically Amplified Tunneling of the Third Kind as a Probe of Minicharged Particles

“…The crucial difference to ALPS is the direction of the magnetic field, which in our scenario is at θ 0, instead of θ = π/2. As a suitable magnet we have identified a presently unused ZEUS compensation solenoid [29] available at DESY. It features a bore of 0.28m diameter and 1.20m length and provides a field strength of B = 5T.…”
