Current X-ray astronomical satellites carry CCD cameras that have moderate performance in imaging, spectroscopy and timing. Future X-ray telescopes with large effective areas and sharp point spread functions require quick readout of focal plane sensors to realize imaging spectroscopy without photon pile-up nor intermittency of its exposure time. To fulfill the requirements, we are developing a...
Gamma-ray bursts (GRBs) are the most luminous explosions in the Universe, releasing an enormous amount of energy on the order of $10^{52–54}$ erg lasting from tens of milliseconds to several hundred seconds, and are regarded as one of the most powerful probes for exploring the early Universe. HiZ-GUNDAM is a proposed future satellite mission aimed at investigating the early Universe (z > 7)...
Future vertex colliders will require detector solutions that minimize material budget, which will be achieved by further integration of detectors, electronics and services. CMOS detectors have been proposed as a breakthrough solution for integration in particle physics experiments. The increased integration level combined with the subsequent higher channel density, and the high-performance...
The Mu3e experiment is on the frontier of charged lepton flavour violating searches and seeks to observe the rare muon decay $\mu^+ \rightarrow e^{+}e^{-}e^{+}$, as well as paving the way globally in terms of cutting-edge ultra low-mass detector technologies. Based at the Paul Scherrer Institute (PSI), a leading Swiss national laboratory near Zurich, the Mu3e experiment consists of four pixel...
In the context of the Pentadimensional Tracking Space Detector project (PTSD), we are currently developing a demonstrator to increase the Technological Readiness Level of LGAD Si-microstrip tracking detectors for applications in space-borne instruments.
Low Gain Avalanche Diodes (LGAD) is a consolidated technology developed for particle detectors at colliders which allows for simultaneous...
Future high-energy physics experiments require trackers with improved timing and spatial resolution, combined with a low material budget. The CASSIA (CMOS Active Sensor with Internal Amplification) project addresses these requirements by developing a monolithic pixel detector with internal amplification through the implementation of gain layers in an industrial 180nm CMOS imaging process.
The...
The recent years have witnessed a growing interest in ultra-fast semiconductor sensors for time-resolved synchrotron light applications. Of special consideration are the Low Gain Avalanche Diodes (LGADs) which provide picosecond timing resolution and an internal gain mechanism, suitable to explore the fast repetition rates of hundreds of MHz and the high photon flux, low energy regime of the...
The Gamma-Ray and AntiMatter Survey (GRAMS) is a proposed mission to explore the MeV gamma-ray sky using a large effective-area Compton camera employing a liquid argon time projection chamber (LArTPC). As part of the concept study, we have developed a compact $5\times 5 \times 10\,\mathrm{cm^3}$ LArTPC prototype, named NanoGRAMS. When a MeV photon enters the LArTPC, it undergoes Compton...
Future tracking and vertex detectors require sensors with finer pitch, im-
proved timing resolution, and minimal power consumption. While monolithic
CMOS pixel sensors (MAPS) offer a promising solution, their performance is
somewhat limited by the small signal generated in their thin sensitive layers,
down to 10 μm in some technologies.
The APICS (Impact Amplification with CMOS Pixel...
Strip detectors are populating the outer trackers of high energy particle experiments. They are convenient for covering large areas of sensitive material since they use less power and have fewer readout channels compared to pixels sensors. Nevertheless, they are typically not manufactured using CMOS production lines since they have to be stitched along the implant of the strip and use several...
