The Atacama Cosmology Telescope (ACT) aims to measure the Cosmic Microwave Background (CMB) temperature anisotropies on arcminute scales. The ACT project is producing high-resolution millimeter-wave maps of the sky, which can be analyzed to provide measurements of the CMB angular power spectrum at large multipoles to augment the extant data to improve estimation of such cosmological parameters as the scalar spectral index and its running, the density of baryons, and the scalar-to-tensor ratio. When combined with X-ray and optical observations, the millimeter-wave maps will help to determine the equation of state of dark energy, probe the neutrino masses, constrain the time of the formation of the first stars, and reveal details of the growth of gravitationally bound structures in the universe.;This thesis discusses the characterization of the detectors in the primary receiver for ACT, the Millimeter Bolometer Array Camera (MBAC). The MBAC is comprised of three 32 by 32 transition edge sensor (TES) bolometer arrays, each observing the sky with an independent set of band-defining filters. The MBAC arrays are the largest pop-up detector arrays fielded, and among the largest TES arrays built. Prior to its assembly into an array and installation into the MBAC, a column of 32 bolometers is tested at approximately 0.4 K in a cryostat called the Super Rapid Dip Probe (SRDP). The purpose of this paper is twofold. First, we will describe the SRDP measurements that supply important TES operating properties. Second, we will expand upon the ideal TES bolometer theory to develop an extended thermal architecture to model non-ideal behaviors of the ACT TES bolometers, emphasizing a characterization that accounts for both the complex impedance and the noise as a function of frequency.

機譯：阿塔卡馬宇宙望遠鏡（ACT）的目的是在弧分鐘尺度上測量宇宙微波背景（CMB）溫度各向異性。 ACT項目正在生成天空的高分辨率毫米波圖，可以對其進行分析，以提供大型多極點的CMB角功率譜的測量結果，以增強現有數據，從而改善對諸如標量光譜指數和它的運行，重子的密度以及標量與張量之比。當與X射線和光學觀測結合使用時，毫米波圖將有助于確定暗能量的狀態方程，探測中微子質量，限制第一批恒星形成的時間以及揭示恒星生長的細節。本文討論了ACT的主要接收器即毫米波陣列相機（MBAC）中探測器的特征。 MBAC由三個32 x 32過渡邊緣傳感器（TES）輻射熱測量計陣列組成，每個陣列都通過一組獨立的頻帶定義濾波器觀察天空。 MBAC陣列是現場最大的彈出式探測器陣列，也是已建成的最大TES陣列之一。在將其組裝成陣列并安裝到MBAC中之前，需要在稱為超級快速浸入式探頭（SRDP）的低溫恒溫器中在約0.4 K的溫度下測試32個輻射熱計的色譜柱。本文的目的是雙重的。首先，我們將描述提供重要的TES操作特性的SRDP測量。其次，我們將擴展理想的TES輻射熱測量計理論，以開發擴展的熱體系結構，以對ACT TES輻射熱測量計的非理想行為進行建模，并強調將復雜阻抗和噪聲作為頻率函數的特征。
