The calorimeters which will operate in experiments at the hadronic Future Circular Collider—FCC-hh—will be one of the key pieces for the complete exploration of collisions between hadrons. This is because the increasing of energy in proton collisions will require detectors that can work in environments under severe radiation, with high-energy rates, presenting a high resolution and low granularity. In this context, the choice of the hadronic calorimeter of the FCC-hh, the Hadronic Barrel (HB) and the extended barrel (HEB), will be inspired by the ATLAS Tile Calorimeter (TileCal). The HB will have 10 layers, with scintillating tiles that will be separated through a reflective material (e.g., Tyvek) and read by wavelength shifting fibers (WLS) of 1 mm in diameter connected to silicon photomultipliers (SiPMs). Our study focuses on the comparison of the luminous signal intensity in the tile in the first layer of the HB and the tile in the last layer of HB, taking into account the dimensions of the tile. A study on the optimization of the signal uniformity was made, by adding a light-absorbing black strip to the tile, and results were compared with similar experiments performed at CERN. The procedure was performed in the Tilemeter, in the Laboratory of Optics and Scintillating Materials (LOMaC) of the Laboratory of Instrumentation and Experimental Particle Physics, in Lisboa.

将在强子未来圆形对撞机（FCC-hh）中进行实验的量热仪将是对强子之间碰撞进行全面探索的关键部件之一。这是因为质子碰撞中能量的增加将需要能够在高辐射率，高解析度和低粒度的强辐射环境下工作的探测器。在这种情况下，FCC-hh强子量热仪，强子管（HB）和加长桶（HEB）的选择将受到ATLAS瓷砖量热仪（TileCal）的启发。HB将具有10层，其闪烁的瓷砖将通过反射材料（例如，特卫强）分开，并由直径为1毫米的波长偏移光纤（WLS）读取，并与硅光电倍增管（SiPM）连接。我们的研究着眼于瓷砖的尺寸，着重于比较HB第一层瓷砖和HB最后一层瓷砖中的发光信号强度。通过在瓷砖上添加一条吸光黑条，对信号均匀性进行了优化研究，并将结果与​​CERN进行的类似实验进行了比较。该程序是在里斯本仪器与实验粒子物理实验室的光学和闪烁材料实验室（LOMaC）的Tilemeter中执行的。并将结果与​​CERN进行的类似实验进行了比较。该程序是在里斯本仪器与实验粒子物理实验室的光学和闪烁材料实验室（LOMaC）的Tilemeter中执行的。并将结果与​​CERN进行的类似实验进行了比较。该程序是在里斯本仪器与实验粒子物理实验室的光学和闪烁材料实验室（LOMaC）的Tilemeter中执行的。
