New Constraints on Axion Mediated Dipole-Dipole Interactions Open
The search for axions sits at the intersection of solving critical problems in fundamental physics, including the strong CP problem in QCD, uncovering the nature of dark matter, and understanding the origin of the universe's matter-antimat…

ETROC1: the first full chain precision timing prototype ASIC for CMS MTD endcap timing layer upgrade Open
We present the design and characterization of the first full chain precision timing prototype ASIC, named ETL Readout Chip version 1 (ETROC1) for the CMS MTD endcap timing layer (ETL) upgrade. The ETL utilizes Low Gain Avalanche Diode (LGA…

The CMOS Pseudo-Thyristor: a zero-static current discriminator circuit Open
A very low power discriminator circuit for pixelized detectors, called the Pseudo-Thyristor is described in this document. It is a positive feedback topology using regular PMOS and NMOS field-effect transistors (FET's) with zero static cur…
