相对论重离子对撞机上的超级开创性高能核相互作用实验（sPHENIX）将对各种核碰撞系统的喷流和重味观测值进行高精度测量，阐明从核子到强耦合夸克-胶子等离子体的强相互作用物质的微观性质。sPHENIX量热计系统的原型于2016年春季在费米实验室测试束设施进行了测试，作为实验T-1044。电磁量能器（EMCal）的原型是由嵌入在钨粉和环氧树脂的混合物中的碳化纤维组成的。强子量热计（HCal）原型由倾斜的钢板与塑料闪烁体交替组成。测试束流的结果表明，EMCal系统中电子的能量分辨率为2.8 + 15.5/E，EMCal + HCal系统中强子的能量分辨率为13.5 + 64.9/E.这些结果表明，所提出的热量计系统的性能满足sPHENIX规格。
The super Pioneering High Energy Nuclear Interaction eXperiment (sPHENIX) at the Relativistic Heavy Ion Collider will perform high-precision measurements of jets and heavy flavor observables for a wide selection of nuclear collision systems, elucidating the microscopic nature of strongly interacting matter ranging from nucleons to the strongly coupled quark–gluon plasma. A prototype of the sPHENIX calorimeter system was tested at the Fermilab Test Beam Facility as experiment T-1044 in the spring of 2016. The electromagnetic calorimeter (EMCal) prototype is composed of scintillating fibers embedded in a mixture of tungsten powder and epoxy. The hadronic calorimeter (HCal) prototype is composed of tilted steel plates alternating with the plastic scintillator. Results of the test beam reveal the energy resolution for electrons in the EMCal is $2.8\%\oplus 15.5\%/\sqrt {E}$ and the energy resolution for hadrons in the combined EMCal plus HCal system is $13.5\%\oplus 64.9\%/\sqrt {E}$ . These results demonstrate that the performance of the proposed calorimeter system satisfies the sPHENIX specifications.
