K07.00002: MCP-PMT Development at Argonne National Laboratory Junqi Xie, chao Peng, Sylvester J Joosten, Zein-Eddine Meziani, Dean Walters, Lei Xia Microchannel plate photomultipliers (MCP-PMTs) have compact electron amplification design, providing them with excellent magnetic field immunity and precision timing performance. Groups at Argonne have been developing MCP-PMTs by applying low-cost MCPs functionalized by the atomic layer deposition technique. Recently, we demonstrated a low-cost whole glass MCP-PMT package design, achieving 3×3 mm2 pixel readout, magnetic field tolerance of over 1.5 Tesla, root-mean-square (RMS) time resolution of 89 ps and transit time spread (TTS) time resolution of 35 ps, fulfilling the critical photodetector requirement for EIC Cherenkov imaging detectors. However, there are two limitations of the current Argonne-fabricated MCP-PMTs: activation area of only 6 × 6 cm2 and quantum efficiency (QE) of 10% limited by the fabrication facility. A 10 × 10 cm2 MCP-PMT fabrication facility was thus designed and constructed to overcome these limitations, and provide with a practical device size prototypes to the Nuclear Physics community. The design of the fabrication facility, its construction and commissioning progress will be reported. The future performance enhancement developments and possible applications which benefit from the existence of such an MCP-PMT fabrication facility will also be discussed. |

K07.00003: Simulation Study of Barrel Electromagnetic Calorimeter Jihee Kim The Electron-Ion Collider (EIC) will be an experimental facility to explore the gluons in nucleons and nuclei, shedding light on their structure and the interactions within. As a part of the ATHENA (A Totally Hermetic Electron-Nucleus Apparatus) proto-collaboration among three detector concepts driven by the EIC community, the ANL group proposes a conceptual design of the electromagnetic calorimeter in the central region. It is a hybrid design utilizing imaging calorimetry based on monolithic silicon sensors (AstroPix) and scintillating fibers embedded in Pb with $-1.5 < \eta < 1.2$ coverage. Nearly all physics processes being pursued at the EIC require the detection of the scattered leptons for the momentum or energy reconstruction and particle identification. In particular, the barrel electromagnetic calorimeter must also detect energy and position of neutral particles such as photons and identify single photons originating from Deeply Virtual Compton Scattering (DVCS) process and photon pairs from $\pi^0$ decays. In this work, I will present the expected performance of photon and neutral pion reconstruction based on simulations of the electromagnetic calorimeter in the central region for the ATHENA proto-collaboration. |

K07.00004: Forward silicon vertex/tracking detector design and R$\&$D for the future Electron-Ion Collider Xuan Li, Yasser Corrales Morales, Matt Durham, Melynda Brooks, Walter Sondheim, Eric Renner, Christopher Prokop, Astrid Morreale The proposed high-luminosity high-energy Electron-Ion Collider (EIC) will provide a clean environment to precisely study several fundamental questions in the high energy and nuclear physics fields. To realize the proposed physics measurements at the EIC, a high granularity detector, which can cover pseudorapidity range from -3.5 to 3.5, provide percentage momentum/energy resolution and be able to separate nanosecond bunch crossings, is required. Within the EIC general detector, a low material budget silicon vertex/tracking detector with fine spatial resolution is critical to carry out a series of hadron/jet measurements at the EIC especially for the heavy flavor product reconstruction/tagging. We will present designs of a proposed forward silicon tracking detector (with pseudorapidity coverage from 1 to 3.5) integrated with different magnet options and the other detector sub-systems for the EIC. The evaluated performance of this detector meets the EIC detector requirements. The detector R$\&$D work for the advanced silicon technology candidates: radiation hard Monolithic Active Pixel Sensor (MALTA) and Low Gain Avalanche Diode (LGAD) will be shown as well. |

K07.00005: Tracking and vertexing based on Monolithic Active Pixel Sensors for the EIC Ernst P Sichtermann, Nicole J Apadula, Yuan Mei, Leo Greiner, Shujie Li, Reynier Cruz Torres, Wenqing Fan, Barbara V Jacak, Xin Dong Experiments at the future Electron-Ion collider pose stringent requirements on the tracking system for the measurement of the scattered electron and charged particles produced in the collision, as well as the position of the collision point and any decay vertices of hadrons containing heavy quarks. Monolithic Active Pixel Sensors (MAPS) offer the possibility of high granularity in combination with low power consumption and mass, making them ideally suited for the inner tracker of the EIC detector(s). In this talk, we will discuss optimized configurations and associated R&D towards a well-integrated, large-acceptance, precision tracking and vertexing solution for the EIC. |

K07.00006: Fast detectors for polarimetry at the EIC Tommaso Isidori, Daniel Tapia Takaki, Amrit Gautam In light of the upgraded capability of particle colliders, new state-of-the-art particle detectors are often required to cope with outstanding radiation rates. The many technical complications arising from this problem pushed the community towards the design of technologies with unprecedented fast response and radiation tolerances. Among their possible applications, these detectors find an important use in the development of Compton polarimeters, devices which are expected to be installed along the electronic beam lines at the EIC. This talk will describe the design of a Compton polarimeter for the EIC based on fast solid state sensors. We will describe the importance of the choice of the sensors, and the design of a fast read-out electronics. Preliminary results based on simulations will also be presented. This work is supported by the U.S. Department of Energy. |
