- QSPIRES
- A web server which is used to remotely query various SPIRES databases (HEP, BOOKS, CONF, INST, etc.). The QSPIRES query is used to locate e-mail addresses for physicists worldwide. QSPIRES is available via the Internet at qspires@slac.stanford.edu.
- QTRM
- Quadrupole TRiM. An extra winding on a quadrupole magnet used for making small adjustments to the field. Sometimes wired to add a small dipole field to the quadrupole, usually for steering purposes.
- Quad
- See Quadrupole.
- QUaD
- QUest at Dasi. Project utilizing the Q U Extra-galactic Survey Tel escope (QUEST) instrument at the South Pole that was installed on the mechanical structure from a previous experiment called DASI (D egree Angular Scale Interferometer).
- Quadrupole
- A four pole magnet used to focus beams. The strength of the field is proportional to the distance from the center. The focusing is in one plane only. In the other plane, the field is defocusing. Quadrupoles may be wired to be horizontally focusing (vertically defocusing) or horizontally defocusing (vertically focusing). At SLAC, they are named after their horizontal effect on the beam.
- Quadrupole TRiM
- See QTRM.
- Quaero
- A web-based computer tool which allows physicists worldwide to search data from Fermilab's DZero experiment. Developed by physicist Bruce Knuteson. Quaero is Latin for 'I search.' ( http://quaero.fnal.gov )
- Qubit
- One QUantum BIT of information.
- Quench
- A change of phase in a superconducting magnet in which the superconducting properties are lost. The energy released can destroy the magnet, if proper precautions are not taken to safely dissipate the stored energy.
- Quencher
- A Superconducting Triplet protection subsystem to initiate a quench and turn off the final triplet. This is done using a capacitive discharge to warm up the wire and bring it out of superconductivity.
- QUEST
- Q U Extra-galactic Survey Telescope. (South Pole)
- QUEST
- QUasar Equatorial Survey Team.
- Quick Access
- An access to a PPS-controlled area defined as being for less than two hours and with fewer than five people.
- QWT
- Quarter Wave Transformer.
