Vibration and Environmental Stability (VES)

The primary focus of Vibration and Environmental Stability (VES) working group is to develop vibrational awareness, expertise, best practices, and tailored solutions for specific issues here at the APS. The VES group can provide engineering support upon request.


The support team has expertise in:

  • DI water systems
  • Temperature control
  • HVAC
  • Vibration measurement and mitigation
  • Structural design
  • Noise measurement and abatement
  • Enclosure and laboratory exhaust systems
  • Electrical power and lighting

Please contact Patti Pedergnana, the User Technical Interface, with VES support requests: Include in the email requester name, requester contact email and/or phone number, beamline or laboratory location associated with the support request, and details regarding the request. If yours is a time-dependent request, note that in the email.


VES meetings are held the fourth Thursday of each month, 10 a.m. to 11 a.m., in Building 401 Room A1100 unless otherwise noted. Part of the meeting will comprise an exchange of ideas or current problems in an open forum.

If you have a VES-related topic on which you would like to share, please contact Sunil Bean or Steve Kearney, VES co-chairs.
