标题： Non-linearity effects on the light-output calibration of light charged particles in CsI(Tl) scintillator crystals

摘要： 在CsI(Tl)晶体中，研究了轻离子（Z<=4）产生的光输出，在检测能量范围（E<=300 MeV）内进行了研究。 通过最近升级的高分辨率阵列（HiRA10）中的10厘米晶体获得了能量-光校准数据集。 我们使用了40,48Ca + CH2在28 MeV/u、56.6 MeV/u、39 MeV/u和139.8 MeV/u下的质子反冲数据，以及专门实验中的直接低能束数据。 我们还使用了40,48Ca + 58,64Ni、112,124Sn碰撞反应中p、d和t粒子的穿透点数据，在139.8 MeV/u下进行。 发现非线性效应，特别是由于Tl掺杂和CsI晶体中的光收集效率，显著影响光输出，因此影响了轻带电粒子探测器响应的校准，尤其是氢同位素。 提出了一种新的经验参数化方法，用于描述氢的光输出L(E,Z=1,A)，以考虑观察到的效果。 结果发现，对于12个HiRA10望远镜簇中的所有48个CsI(Tl)晶体都是一致的。 显示英文摘要

摘要： The light output produced by light ions (Z<=4) in CsI(Tl) crystals is studied over a wide range of detected energies (E<=300 MeV). Energy-light calibration data sets are obtained with the 10 cm crystals in the recently upgraded High-Resolution Array (HiRA10). We use proton recoil data from 40,48Ca + CH2 at 28 MeV/u, 56.6 MeV/u, 39 MeV/u and 139.8 MeV/u and data from a dedicated experiment with direct low-energy beams. We also use the punch through points of p, d, and t particles from 40,48Ca + 58,64Ni, 112,124Sn collisions reactions at 139.8 MeV/u. Non-linearities, arising in particular from Tl doping and light collection efficiency in the CsI crystals, are found to significantly affect the light output and therefore the calibration of the detector response for light charged particles, especially the hydrogen isotopes. A new empirical parametrization of the hydrogen light output, L(E,Z=1,A), is proposed to account for the observed effects. Results are found to be consistent for all 48 CsI(Tl) crystals in a cluster of 12 HiRA10 telescopes.
