Calibration of the L3 BGO Calorimeter Using an RFQ Accelerator
An improved calibration technique based on a radio-frequency-quadrupole (RFQ) accelerator is presented. A high-intensity flux of 17.6 MeV photons, produced by radiative capture of 1.85 MeV protons from the RFQ in a lithium target, is used to calibrate 11000 crystals of the L3 BGO calorimeter. In this paper, we present results obtained for the calibration of 1997 and 1998 L3 data samples. For th...
متن کاملNorth-Holland, Amsterdam CALIBRATION OF THE L3 BGO ELECTROMAGNETIC CALORIMETER WITH A RADIOFREQUENCY QUADRUPOLE ACCELERATOR
A new calibration technique based on radiative capture of protons from an RFQ accelerator in a lithium target, which makes use of the resultant high intensity flux of 17 .6 MeV photons, has been developed and tested . The technique is capable of calibrating the thousands of BGO crystals in the L3 electromagnetic calorimeter at once, with an absolute accuracy of better than 1 % in 1-2 h. Systema...
متن کاملTemperature Dependence Calibration and Correction of the DAMPE BGO Electromagnetic Calorimeter
A BGO electromagnetic calorimeter is built for DArk Matter Particle Explorer(DAMPE) mission. The temperature effect of BGO ECAL has been investigated with a thermal vacuum experiment. The light output of BGO crystal depends on temperature significantly. Temperature coefficient of each BGO crystal bar has been calibrated, and a correction method is also presented in this paper.
متن کاملThe GRAAL high resolution BGO calorimeter and its energy calibration and monitoring system
We describe the electromagnetic calorimeter built for the GRAAL apparatus at the ESRF. Its monitoring system is presented in detail. Results from tests and the performance obtained during the first GRAAL experiments are given. The energy calibration accuracy and stability reached is a small fraction of the intrinsic detector resolution. Preprint submitted to Elsevier Preprint 2 February 2008
متن کاملRadiation resistance and fluorescence of europium doped BGO crystals
We report on a study of the radiation resistance and fluorescence of bismuth germanate scintillation crystals doped with europium (BGO : Eu). The transmission spectrum, the light output and the fluorescence spectrum of BGO : Eu crystals were measured before and after irradiation . The radiation resistance of BGO : Eu crystals was found to be increased with increase of europium doping. A red flu...
