	The upgrade program of the ESRF concerns in terms of electron storage ring vacuum chambers mainly the insertion device (ID) sectors. Here the length available for the production of intense synchrotron light is being increased from five to six or even seven meters. The presence of canted ID sectors where two independent synchrotron light beams will be produced in the same straight section requires new quadrupole chambers compatible with the new geometry. A number of long insertion device vacuum chambers for the new ID sectors has already been produced by ESRF and coated with non-evaporable getter (NEG) material, a new generation of in vacuum undulators for the extended ID sections are under preparation. This paper outlines the status of the modification of the vacuum system and informs about consequences for the ESRF NEG coating activity and some recent improvements of the vacuum measurement and control system.

	In the frame of the ESRF upgrade program, the Residual Gas Analyzer (RGA) system has been reviewed. A campaign of RGA refurbishment has been started recently giving more reliability and accuracy on partial pressure vacuum control. Based on new technologies and our operating experience, new RGA monitoring application and diagnostic tools have been developed. This paper outlines the evolution of the actual RGA system focusing on the controlled hardware installation description, on software and user interface developments.

In the frame of the ESRF upgrade program, the Residual Gas Analyzer (RGA) system has been reviewed. A campaign of RGA refurbishment has been started recently giving more reliability and accuracy on partial pressure vacuum control. Based on new technologies and our operating experience, new RGA monitoring application and diagnostic tools have been developed. This paper outlines the evolution of the actual RGA system focusing on the controlled hardware installation description, on software and user interface developments. The continuous follow up of a defined number of partial pressure measurements using different dynamic control modes will be described.
