Dean R Walters Undulator Vacuum October 12-13, 2004 Facility Advisory Committee Undulator Vacuum System/Mechanical Beamline Diagnostics RFBPM Different type under consideration Highlights of Schedule Vacuum Testing of Diagnostics Components What drives this issue Status of Testing

Dean R Walters Undulator Vacuum October 12-13, 2004 Facility Advisory Committee Beamline Diagnostics C-Band RFBPM now being considered instead of X-Band C-Band has the possibility of using industry supplied electronics According to published literature resolution ~30 nm

Dean R Walters Undulator Vacuum October 12-13, 2004 Facility Advisory Committee Highlights of the Schedule Design work to start March 2005 Timing of Design work based of funding during Continuing Resolution Use intervening time to research C-Band RFBPM (ANL) Goal is to have BPM mechanical design by June 2005 Goal is to have (3) test BPMs by September 2005 Currently this schedule is undergoing a review Beamline Diagnostics

Dean R Walters Undulator Vacuum October 12-13, 2004 Facility Advisory Committee Beamline Diagnostics Vacuum Testing of Diagnostics Components What drives this issue The Diagnostics Station is considering the use of motion components in the vacuum section where we do not have a lot of experience. Slides and Stages Motors The initial concept was to put the motion components in the vacuum for reasons of positional accuracy. The design is at a point where changes are possible to move things in and out of vacuum The intention is to subject components to residual gas analysis and outgassing measurement to qualify them for use.

Dean R Walters Undulator Vacuum October 12-13, 2004 Facility Advisory Committee Beamline Diagnostics

Dean R Walters Undulator Vacuum October 12-13, 2004 Facility Advisory Committee Beamline Diagnostics Status of Testing A draft test procedure has been written that covers both residual gas analysis and outgassing measurement. The Test Set-up is assembled The Set-up has completed a troubleshoot/ clean-up process The Set-up is in the process of establishing a base performance profile Suppliers are being contacted for test samples

Dean R Walters Undulator Vacuum October 12-13, 2004 Facility Advisory Committee Schedule Diagnostics Vacuum System

Dean R Walters Undulator Vacuum October 12-13, 2004 Facility Advisory Committee Conclusions: Prototype Chamber construction progressing The prototype Bellows has been modeled and after issuing drawings it will enter the fabrication phase. The order of the Beamline Components is still undergoing some adjustments but it is firming to allow design of the cradle assembly A new direction for the RFBPM is being considered and work on it is schedule for March 2005 Motion components vacuum testing has just entered the first stage of testing.
