摘要:

MIPP实验的目的是研究使用费米实验室主注入器的光束在各种目标上的π,K和p相互作用中光子,π介子,K介子和核子的包容性生产。量热计的功能是测量向前运动的中子和光子的产生。电磁量热计由10块铅板组成,铅板上散布着正比室。其次是强子量热计,其中64个钢板穿插闪烁体。所提供的数据是用各种靶和束动量从5 GeV/c到120 GeV/c收集的。讨论了用电子、π介子、K介子和质子对两种量热计进行能量标定的问题。对电子的分辨率为0.27/sqrt(E),对强子的分辨率为0.554/sqrt(E),常数项为2.6%。在中子样品上测试了量热计的性能。

英文摘要:

The purpose of the MIPP experiment is to study the inclusive production of photons, pions, kaons and nucleons in pi, K and p interactions on various targets using beams from the Main Injector at Fermilab. The function of the calorimeters is to measure the production of forward-going neutrons and photons. The electromagnetic calorimeter consist of 10 lead plates interspersed with proportional chambers. It was followed by the hadron calorimeter with 64 steel plates interspersed with scintillator. The data presented were collected with a variety of targets and beam momenta from 5 GeV/c to 120 GeV/c. The energy calibration of both calorimeters with electrons, pions, kaons, and protons is discussed. The resolution for electrons was found to be 0.27/sqrt(E), and for hadrons the resolution was 0.554/sqrt(E) with a constant term of 2.6%. The performance of the calorimeters was tested on a neutron sample.
