Spring 2025: Upcoming
| Date | Description |
|---|---|
TUESDAY 4/1/25 1:30 PM Special Location: Gross Hall 103 | Brooke Russell, MIT LArPix Pixelated Charge Readout System LArPix is an end-to-end pixelated charge readout system for 3D imaging at the millimeter-scale in multi-tonne liquid argon time-projection chambers (LArTPCs). Leveraging large-scale commercial fabrication techniques, the system is designed to be highly scalable and robust, enabling low-cost quick-turn system production at industry standard. The system is based on the LArPix ASIC, a cryo-compatible, low-power detector system-on-a-chip composed of 64 input channels. The analog front-end on each channel includes an integrating charge-sensitive amplifier, a tunable discriminator, and an 8-bit successive approximation register analog-to-digital converter. A digital core is shared across all ASIC channels, managing digital multiplexing and digital configuration and control. LArPix performance using prototype detectors at the >10^5 channel scale will be presented, and progress on design of 10^7-10^8 channel systems will be discussed. |
