Efficiency calibration of a Ge(Li) detector by absolute counting of fallout nuclides by means of the 4πβ-γ coincidence method
1975
Abstract The 4 π β - γ coincidence method proves to be very suitable for absolute counting of fallout nuclides. Using such nuclides, absolute calibration of a Ge(Li) detector was carried out for different geometry positions.
The energy calibration of LEP in the 1993 scan
1995
This report summarizes the procedure for providing the absolute energy calibration of the LEP beams during the energy scan in 1993. The average beam energy around the LEP ring was measured in 25 calibrations with the resonant depolarization technique. The time variation of this average beam energy is well described by a model of the accelerator based on monitored quantities. The absolute calibration of the centre of mass energies of the off-peak points is determined with a precision of 2 parts in 10(5) resulting in a systematic error on the Z-mass of about 1.4 MeV and on the Z-width of about 1.5 MeV.
