Abstract	A synchrotron radiation profile monitor will be used in the LHC to measure the beam profiles from the injection energy of 450 GeV to the nominal energy of 7 TeV. The radiation will be provided by a sequence of two separate magnets: a two-periods superconducting undulator and the beam separation dipole D3. After a short description of the profile monitor layout, the paper reviews the electromagnetic and mechanical design of the undulator, providing 5 T at 4.5 K in a 60 mm gap with a period of 280 mm and reports on the fabrication and cold test results of a first half period prototype.
