A Study of the Water Cherenkov Calorimeter

A study on the lateral distribution of Cherenkov light in extensive air showers

The dependence of the lateral distribution of Cherenkov light in simulated extensive air showers to the energy and the mass of the primary cosmic rays has been studied. It has been shown that a previous claim about mass independent proportionality of shower energy to the total Cherenkov photon number is not valid in energies below EEAS ~ 1014 eV. We have found that the core distance of the so c...

Atmospheric neutrinos in Soudan 2

allows a measurement which is independent of an absolute ux or exposure calculation. Soudan 2 is an iron calorimeter with di erent experimental systematics from the water Cherenkov detectors and with a di erent geometry and detection technique from from the Frejus experiment. A large veto shield placed against the cavern wall allows the identi cation of particles entering the detector from the ...

Callibration of a homemade 4-fold Water Cherenkov Detector array, by detection of EAS events

Simulation Calibration of an Extensive Air Shower array, by a logged data set of its small prototype

Alborz observatory is an EAS array in the heights of Alborez mountain chain near Tehran. For the development of the array, more number of detectors is inevitable. The managing the financial resources and achieving the highest efficiency of the array is important for the project. Therefore, Water Cherenkov Detectors has been used for 9 months in the same way as the previous experiment with Scint...

Zero Degree Cherenkov calorimeters for the ALICE experiment

The collision centrality in the ALICE experiment will be determined by the Zero Degree Calorimeters (ZDCs), that will measure the spectator nucleons energy in heavy ion collisions. The ZDCs detect the Cherenkov light produced by the fast particles in the shower that cross the quartz fibers, acting as the active material embedded in a dense absorber matrix. Test beam results of the calorimeters ...
