A parameterized energy correction method for electromagnetic showers in BGO-ECAL of DAMPE

Temperature 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.

Fractal Electromagnetic Showers

We study the self-similar structure of electromagnetic showers and introduce the notion of the fractal dimension of a shower. Studies underway of showers in various materials and at various energies are presented, and the range over which the fractal scaling behaviour is observed is discussed. Applications to fast shower simulations and identification, particularly in the context of extensive a...

A novel dual energy CT-based attenuation correction method in PET/CT systems: A phantom study

  In present PET/CT scanners, PET attenuation correction is performed by relying on the information given by CT scan. In the CT-based attenuation correction methods, dual-energy technique (DECT) is the most accurate approach, which has been limited due to the increasing patient dose. In this feasibility study, we have introduced a new method that can implement dual-en...

A method for detection of muon induced electromagnetic showers with the ANTARES detector

The primary aim of ANTARES is neutrino astronomy with upward going muons created in charged current muon neutrino interactions in the detector and its surroundings. Downward going muons are background for neutrino searches. These muons are the decay products of cosmic-ray collisions in the Earth’s atmosphere far above the detector. This paper presents a method to identify and count electromagne...
