Characterization measurements of $25 \mathrm{\mu m} \times 25 \mathrm{\mu m}$ pitch 3D silicon sensors are presented, for devices with active thickness of $150\mu$m. Evidence of charge multiplication caused by impact ionization below the breakdown voltage is observed. Small-pitch 3D silicon sensors have potential as high precision 4D tracking detectors that are also able to withstand...
As upcoming high energy physics experiments move towards higher energies and luminosities, there is a strong need to improve the measurement precision of tracking detectors. High-granularity pixel detectors are a feasible option and would enhance high-priority physics, especially signatures with heavy quark decays, but with the added cost of increased data rates. The objective of the...
We present a novel, blue-sky detector concept that aims to replace the relatively slow process of charge-drift in a semiconductor with light-collection from scintillating quantum dots (QDs) in order to achieve ultimate timing performance in a thin, low-mass material for future charged-particle detectors. Here we show measured detection performance using self-assembling InAs QDs inside of a 25...
Thin film technology, as used in LCD displays and photovoltaics, could enable the fabrication of large-area, low-mass tracking detectors on flexible substrates, ultimately building towards roll-to-roll printing. Thin film detectors may also potentially incorporate electronic elements into a monolithic design, or involve the deposition of active sensor material onto a readout ASIC. Physical and...
We present the development of hybrid devices made from a thick ionization target layer of amorphous selenium (aSe) coupled to a silicon complementary metal-oxide-semiconductor (CMOS) active pixel array for charge readout. The CMOS pixels are instrumented to measure both the amplitude and time-of-arrival (TOA) of the charge signal for 3D tracking. The high spatial resolution in a solid-state...
The physics drivers of experiments at FCCee motivate detector specifications that exceed the current state-of-the-art. Realizing the full scientific potential of FCCee will require new and cross-cutting technological development. This talk will present the status of FCCee physics targets, detector designs, and next steps in the context of CPAD R&D areas and synergistic progress for future...
