glass walled walkways across the atrium. The astrophysics seminar room is named after Sir Bernard Lovell, founder of Jodrell Bank Observatory. The fourth floor contains a number of labs, an RFI screened room and clean room, all for astrophysics instrumentation construction, such as receivers for the Lovell Telescope and the Planck spacecraft. In January 2008, the Project Design Office for the Square Kilometre Array relocated to Manchester to be hosted by the JBCA, co-ordinating the global efforts in constructing the next generation radio telescope. The Photon Science Institute houses laboratories shielded from electromagnetic radiation and resistant to vibration, and features instruments such as a broadband sum frequency spectrometer, and a spectroscopic photon echo measurement kit. A bridge on the third floor connects from Astrophysics to the Photon Science Institute, but retaining that finger's resistance to mechanical vibration.
