The Cryogenic Underground Observatory for Rare Events (CUORE) is the most sensitive experiment searching for neutrinoless double-beta decay ($0νββ$) in $^{130}\text{Te}$. CUORE uses a cryogenic array of 988 TeO$_2$ calorimeters operated at $\sim$10 mK with a total mass of 741 kg. To further increase the sensitivity, the detector response must be well understood. Here, we present a non-linear thermal model for the CUORE experiment on a detector-by-detector basis. We have examined both equilibrium and dynamic electro-thermal models of detectors by numerically fitting non-linear differential equations to the detector data of a subset of CUORE channels which are well characterized and representative of all channels. We demonstrate that the hot-electron effect and electric-field dependence of resistance in NTD-Ge thermistors alone are inadequate to describe our detectors' energy dependent pulse shapes. We introduce an empirical second-order correction factor in the exponential temperature dependence of the thermistor, which produces excellent agreement with energy-dependent pulse shape data up to 6 MeV. We also present a noise analysis using the fitted thermal parameters and show that the intrinsic thermal noise is negligible compared to the observed noise for our detectors.

Development and characterization of a large area silicon pad array for an electromagnetic calorimeter
我们目前的研究和开发工作的第一个版本的6*6阵列的硅垫探测器,在印度进行,为拟议的前向量热计(FOCAL)的ALICE合作升级计划的一部分,在欧洲核子研究中心。主要的动机是开发一个大面积的硅垫阵列实现高能量物理实验的挑战性要求,如低漏电流,高击穿电压,并评估其性能作为原型硅钨(Si-W)电磁(EM)量能器中的有源层。为了实现这些目标,在班加罗尔的Bharat Electronics Limited,在4英寸高电阻率N型晶片上设计了一个36焊盘的硅传感器,其单个焊盘尺寸为1 cm 2。该传感器已被用于组装原型硅钨量热计,并成功地与高能粒子束测试。本文报道了大面积硅传感器的设计、研制及其在实验室用放射源和高能粒子束上的特性。

CEPC(Circular Electron and Positron Collider)是我国粒子物理界提出的大型实验装置。它的一个运行选项是希格斯工厂。量热仪是本实验的主要组成部分,用于测量射流能量。半数字强子量能器(SDHCAL)是强子测量的一种选择。GEM探测器以其高位置分辨率和灵活的结构成为SDHCAL有源层的候选材料之一。本文的主要目的是为基于GEM的半数字强子量能器提供一种可行的读出方法。设计并实现了一个小型样机,包括前端板和数据接口板。电子原型已经过测试。所有通道的等效RMS噪声低于0.35fC。动态范围高达500fC,增益变化小于1%。读出电路应用于双层GEM探测器上,读出垫为1cm*1cm。结果表明,该电子学与探测器工作良好。MIP的检测效率在95%以上,阈值为5fC。
