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:

  • all pressure vessels and pressure sources including cryogenics, pneumatic, hydraulic and vacuum
  • vacuum systems are considered pressure systems due to their potential for catastrophic failure from backfill pressurization
  • associated hardware (e.g., gauges and regulators), fittings, piping, pumps and pressure relief devices are integral parts of a pressure system

The Pressure Systems Committee membership is:

  • Engineering Division Manager (Will Oren, Chair, ext. 7344)
  • Cryogenic Systems Engineer (Nate Laverdure, ext. 6260)
  • Superconducting Radio Frequency Structures QA/CI Engineer (Jacob Hicks, ext. 7193)
  • Facilities Management Engineer (Carroll Jones, ext. 7672)
  • Experimental Hall Engineer (Timothy Whitlatch, ext. 5087)
  • Environmental, Safety and Health Representative (George Perry, ext. 7841)
  • Performance Assurance Representative (Steve Smith, ext. 7007)
  • Target Group Engineering Physicist (Dave Meekins, ext. 5434)
  • and other technical experts as appointed by the chairperson
