High Homogeneity Solenoidal Magnet for Cesium Frequency Standard
نویسندگان
چکیده
In Cs frequency standards a zone of highly uniform magnetic flus density, lower in value of 0.1 T, is required The magnetic homogeneity value is tied to the overall accuracy of the standard and, for an accuracy of a design value 1 p.p.m. is required. For this purpose a resistive solenoid 700 mm long with a bore radius of 32.5 mm has been designed and built. This paper reports the design process, the measurements on the manufactured magnet and the shimming strategy used to reach the homogeneity target.

متن کاملA Solenoidal Capture System For Neutrino Production
This paper describes the use of a high field solenoidal magnet to capture secondary pions from the production target. The captured pions subsequentially decay to produce the neutrino beam. A pion capture system using a high field solenoid magnet has been proposed for the muon collider[1]. This technology would also be available for neutrino beam production. It will be shown that a high field so...
متن کاملRf Tests of an 805 Mhz Pillbox Cavity at Lab G of Fermilab*
We report recent high power RF tests on an 805 MHz RF pillbox cavity with demountable windows for beam apertures at Lab G of Fermilab, a dedicated facility for testing of MUCOOL (muon cooling) components. The cavity is installed inside a superconducting solenoidal magnet. A 12 MW peak RF power klystron is used for the tests. The cavity has been processed both with and without magnetic field. Wi...
متن کاملTau decays at the B-factories
Today progress in tau physics proceeds mostly at the two B-factories BABAR and Belle, where unprecedented statistics of tau pair events produced in ee annihilations have been recorded. Both experiments rely on “B-factories” operating at a centre-of-mass energy at and around the Υ(4s) peak (10.58GeV). BABAR operates at the PEP-II complex at SLAC, which collides 9GeV electrons against 3.1GeV posi...
متن کاملPhoton-trap spectroscopy of mass-selected ions in an ion trap: optical absorption and magneto-optical effects.
A novel experimental technique has been developed to observe a trace of optical absorption of free mass-selected ions. The technique combines a linear radio-frequency ion trap with a high-finesse optical cavity to perform cavity ring-down spectroscopy (photon-trap spectroscopy for generality), where the storage lifetime of photons in the cavity provides a sensitivity high enough to probe the tr...
