摘要:

欧洲核子研究中心大型强子对撞机ALICE实验的时间投影室具有高度集成的探测器读出电子设备。它遵循高能物理实验的一般趋势,将前端电子设备尽可能靠近探测器-距离其有效体积只有10厘米左右。由于靠近光束和相互作用区域,电子设备受到适度的辐射负载,这使得我们能够使用商业现成的组件。然而,它们需要被仔细地选择和鉴定为辐射硬度,并且必须采取措施来保护它们的功能免受软错误,即单粒子扰乱。在这里,我们报告的第一次测量大型强子对撞机感应辐射的影响ALICE前端电子和他们如何证明的期望。

英文摘要:

The Time Projection Chamber of the ALICE experiment at the CERN Large Hadron Collider features highly integrated on-detector read-out electronics. It is following the general trend of high energy physics experiments by placing the front-end electronics as close to the detector as possible -- only some 10 cm away from its active volume. Being located close to the beams and the interaction region, the electronics is subject to a moderate radiation load, which allowed us to use commercial off-the-shelf components. However, they needed to be selected and qualified carefully for radiation hardness and means had to be taken to protect their functionality against soft errors, i.e. single event upsets. Here we report on the first measurements of LHC induced radiation effects on ALICE front-end electronics and on how they attest to expectations.
