I will report on our recent progresses on developing scaled superconducting single photon detectors embedded in integrated photonic circuits. Yale’s waveguide SSPD design utilizes the concept of evanescent complete absorption of light by a nanowire fabricated atop a waveguide (Fig.1). It overcomes the tradeoff between detection efficiency and speed in conventional meander SSPD designs [1,2]....

Photodetection plays a key role in basic science and technology, with exquisite performance having been achieved down to the single photon level. Further improvements in photodetectors would open new possibilities across a broad range of scientific disciplines, and enable new types of applications. However, it is still unclear what is possible in terms of ultimate performance, and what...

The rst commercially-produced LAPPDTM photodetectors[1] are now available
from Incom, Inc[2]. An informal collaboration of Fermilab, Incom, and the University
of Chicago (UofC) has been developing plans to optimize the timing resolution and
to characterize the performance and life-time of several of the newly available Incom
modules at the Fermilab Testbeam Facility . These modules will...

The cloud and bubble chambers have been used historically for particle detection, capitalizing on supersaturation and superheating respectively. We now present the snowball chamber, which utilizes supercooled liquid. In our prototype, an incoming particle triggers crystallization of purified water. We demonstrate that water is supercooled for a significantly shorter time with respect to...

Calorimeters for particle physics experiments with integration time of a few ns will substantially improve the capability of the experiment to resolve event pileup and to reject backgrounds. In this paper the time development of hadronic showers induced by 30 and 60 GeV positive pions and 120 GeV protons is studied using Monte Carlo simulation and beam tests with a prototype of a sampling...

In high energy physics (HEP) and nuclear physics (NP) experiments, total absorption electromagnetic calorimeters (ECAL) made of inorganic crystals are known for their superb energy resolution and detection efficiency for photon and electron measurements. A crystal ECAL is thus the choice for those experiments where precision measurements of photons and electrons are crucial for their physics...

WLS Capillaries are being developed for optical calorimetry applications, and particularly for sampling calorimetry configurations. The WLS dyes can be tailored appropriately to provide wave shifting for various scintillation materials. Fabricated from radiation hard quartz, these elements are capable of withstanding high radiation doses and could be used broadly for EM applications in fixed...

In recent years, the development of Si CMOS quanta image sensors (QIS) has enabled room-temperature, non-avalanche photon counting in the visible spectrum regime by transferring a photoelectron to a tiny capacitor (C~400 aF), thereby inducing a readable voltage change on the order of 0.4 mV using correlated double sampling method. These non-avalanche single photon detectors (SPDs), based on...

The Large Area Picosecond Photo-Detector (LAPPD™) is a microchannel plate (MCP) based planar geometry photodetector featuring single-photon sensitivity, semitransparent bi-alkali photocathode, millimeter spatial and picosecond temporal resolutions and an active area of to 350 square centimeters. The “baseline” LAPPD™ employs a borosilicate float glass hermetic package. Photoelectrons are...

Particle IDentification (PID) is fundamental to nuclear and particle physics experiments. Fast-timing MCP-PMTs are ideal candidate for PID sensors if the price is affordable. We report detailed design, fabrication and characterization of Argonne 6 × 6 cm$^2$ fast timing photodetectors based on next-generation microchannel plates (MCP). The whole assembly is made of low-cost borosilicate glass...

Precisely controlled metal-metal oxide nanocomposite layers prepared by atomic layer deposition (ALD) exhibit material properties that can be tuned over a broad range by adjusting the metal content such as band gap, absorption coefficient, resistivity, and electrochemical corrosion resistance. Consequently, these metal-metal oxide nanocomposites are well suited especially as a resistive layers...

The Gen-II LAPPD is a 20$\times$20 cm$^2$ MCP-based photo-detector that has a monolithic ceramic detector base with an anode capacitively coupled through a thin metal film to an application-specific readout pattern outside of the vacuum package.
We discuss the development of the *air-transfer* process for the Gen-II LAPPD assembly. In this process a hermetic seal between the top window with...

Over the last years, we have worked on the concept of 3D digital SiPM and demonstrated critical steps towards there realization from CMOS design to fabrication process. We will review the main building blocks of the 3D digital SiPM, the development we have led and the forecasted and needed R&D. This will include CMOS design for arrays of ultra-low single photon timing resolution...

Aside from a large variety of direct applications, Silicon-based photo-multipliers (SiPMs) are also replacing photo-multiplier tubes in the net generation of liquid noble experiments (Argon and Xenon). However, current photo-detection efficiency (PDE) values, at peak emission wavelengths for xenon (175 nm) and argon (128 nm), range between 5% and 25%, requiring in some instance the use of a...
