Abstract: Commissioning of the ultra-high vacuum systems for the 3 GeV Diamond Light Source is in progress. All the machine vacuum systems are installed, under vacuum and performing well. The vacuum control system and machine protection systems are also operational. The measured static pressure in the storage ring is 5 x 10-10 mbar. Pressure rises up to the 10-8 mbar region have been observed during initial beam tests at 700 MeV 2 mA. The effective initial photon stimulated desorption (PSD) yield is estimated to be of order 10-3 molecules per incident photon which is in agreement with expectations.
