Precision Engineering Laboratory

Tasks

The objective of the PEL is to contribute to the specification of the accuracy and manufacturing follow-up of beamline instruments and the performance of acceptance tests and calibration of precision instruments for the beamlines.

With a surface area of 105 m2, of which a half is maintained at a temperature of 20° C ± 0.3°C and a humidity of 50% ± 5%, it caters for dimensional metrology and testing of precise mechanical components, such as the measurement of the sphere of confusion of diffractometers, the calibration of rotary and linear motions and encoders, the testing of monochromators, etc.

Equipment available

The instrumentation available includes (follow links in left menu for detailed specifications):

• two laser interferometers for linear, angular, straightness, squareness, parallelism and time based measurements,
• an angular calibration bench,
• photoelectric autocollimators,
• electronic level,
• electronic dial indicators,
• granite surface tables,
• a data acquisition and motion control system.

The main projects managed by the PEL, some performed in collaboration with other groups (Mechanical Engineering group, workshop, beamline personnel)

include:

• 8-axes diffractometer for ID1,
• two 5-axes Kappa diffractometers for ID14,
• 6-axes Kappa diffractometer for ID11,
• high accuracy 3DXRD vertical axis air bearing goniometer for ID11,
• ESRF reference angular calibration bench with an accuracy better than ±0.3 arc sec.
