Pressure Systems

In response to DOE 10CFR851 JLab formed a Pressure System Committee to define the Lab's policies and procedures and “ensure that pressure systems are designed, fabricated, tested, inspected, maintained, repaired, and operated by trained and qualified personnel in accordance with applicable and sound engineering principles.”

Pressure Systems are defined as:

  • any combination of vessels, piping, instrumentation (e.g. gauges), and/or equipment (e.g. pumps or compressors) either containing a fluid under internal pressure or exposed to external fluid pressure.  Note that vacuum systems are a subclass of pressure systems.

The Pressure Systems Committee membership is:

  • Target Group Engineering Physicist (Dave Meekins, Chair, ext. 5434)
  • Engineering Mechanical Engineer (Joseph Lamont, ext. 7260)
  • Cryogenic Systems Engineer (Nate Laverdure, ext. 6260)
  • Superconducting Radio Frequency Structures QA/CI Engineer (Jacob Harris, ext. 7193)
  • Environment, Safety and Health Representative (Chad Bailey, ext. 7052)
  • Facilities Management Engineer (Carroll Jones, ext. 7672)
  • Experimental Hall Engineer (Timothy Whitlatch, ext. 5087)
  • Performance Assurance Representative (Steve Smith, ext. 7007)
  • Welding Program Manager (Jenord Alston, ext. 5859)
  • and other technical experts as appointed by the chairperson
