Tesla 49-pole superconducting wiggler with 16 mm magnetic gap and 60 mm period for Diamond Light Source (England) has been fabricated in Budker INP. A first wiggler test was carried out in bath cryostat in BINP on July 2005. The first wiggler test in own cryostat was performed in BINP on January 2006. This test includes field integrals meas- urements with stretched wire method and field measurements with hall probe. All this measurements was repeated on April 2006 in DLS. Design of special magnetic measure- ment system with anti-chamber and main wiggler tests results are presented in this paper.

The wake-field undulator (WFU) radiation mechanism (first described in Ref.*) open up new opportunities for generating high brightness ultra-short wavelength light. The core of WFU radiation mechanism consists in photon emission by a short bunch of relativistic charged particles undulating in the nonsynchronous harmonics of wakefields, which are induced as the bunch moves through a periodic corrugated waveguide. There is interest in carrying out experiments on detecting the WFU radiation. This work is devoted develop- ment of experimental methods on viewing WFU radiation in visual range. We consider possibilities of applying short-pulsed ampere range electron beams with energy 100 MeV accelerated in a rf linac operating in energy stored mode. The WF undulator characteris- tics is presented. We analyze possible sources of background radiation such as: thermal radiation of a hot cathode; inelastic scattering of beam electrons on a residual gas; bremsstrahlung radiation of beam electrons on nucleus of a residual gas; synchrotron and diffraction radiation. The ways of decreasing influence of the background radiation on a
valid signal are considered. [*] A. Opanasenko, Proc. http://arxiv.org/abs/physics/0209100
