Observation of high-energy sources requires gamma-ray telescopes aboard balloons or satellites to study thermal and non thermal phenomena (black holes, neutron stars, active galactic nuclei, supernovae, supernova remnants, and gamma-ray bursts). In recent years, R&D has been mainly active to improve the sensitivity required for polarimetry. In this context, a concept of a Time Projection...

For next MeV gamma-ray astronomy, we developed Electron Tracking Compton Camera (ETCC) consisting of a Time projection Chamber and pixel scintillators. By measuring the track of an electron, ETCC measures the direction of gamma-rays as a small arc, which provides a good background rejection using the kinematical test and energy loss rate of the track (particle identification), and clear...

The Cherenkov Telescope Array (CTA) is the next generation ground-based instrument for the detection of cosmic gamma-rays with energies from about 20 GeV up to several hundred TeV. It is envisaged to be comprised of large-, medium- and small-sized telescopes (23m, 10-12m and 4m mirror aperture, respectively). Within the scope of the FlashCam project, a novel camera for the medium-sized...

The Cherenkov Telescope Array (CTA) is an atmospheric Cherenkov observatory that will image the cosmos in very-high-energy gamma rays. CTA will study the highest-energy particle accelerators in the Universe and potentially confirm the particle nature of dark matter. We have designed an innovative Schwarzschild-Couder telescope which uses two mirrors to achieve excellent optical performance...

The High Altitude Water Cherenkov (HAWC) Observatory, located on the Sierra Negra plateau (4100m a.s.l.) in central Mexico, is currently under construction and scheduled for completion at the end of summer 2014. The detector is comprised of tightly-packed optically-isolated water tanks, each 5 m tall and 7.3 m in diameter, which are instrumented with 4 Hamamatsu photomultiplier tubes. The...

Citiroc is a 32-channel front-end ASIC designed to readout silicon photo-multipliers (SiPM).
Citiroc allows triggering down to 1/3 pe and provides the charge measurement with a good noise rejection. Moreover, Citiroc outputs the 32-channel triggers with a high accuracy (100 ps).
An adjustment of the SiPM high-voltage is possible using a channel-by-channel DAC connected to the ASIC inputs....

The hot and energetic Universe has been selected by ESA as its next large
class mission with a scheduled launch date in 2028. This mission will have a large
collecting area (2 m2) with focussing optics and in the focal plane two interchangeable
instruments: a Si-based DEPFET detector which is optimised for its field of view
and its count rate capability. The second instrument is a...

We have been developing a monolithic active pixel sensor with the silicon-on-insulator (SOI) CMOS technology for use in future X-ray astronomical satellite mission. Our objective is to replace the X-ray Charge Coupled Device, which is the standard detector in the field, by offering high coincidence time resolution (โผ 50 ns), superior hit-position readout time (โผ 10 ฮผs), and wider bandpass (0.3...

We have been developing X-ray SOIPIXs, monolithic active pixel sensors based on the Silicon-On-Insulator (SOI) CMOS technology for next-generation X-ray astronomy satellites. Their high time resolution (~micro sec) and event trigger output function enable us to reduce non-X-ray background by two orders of magnitude at 20 keV, compared with X-ray CCDs widely used in current X-ray astronomy...

PoGOLite is a balloon-borne hard X-ray polarimeter. It determines polarisation by measuring the azimuthal angular distribution of Compton scattered photons in a plastic scintillator array. The use of an all plastic target yields a relatively large but low mass detection area. The dominant source of background for the polarisation measurements has been shown through Geant4 simulations to...

After almost 35 years since their suggestion as a good solution to the strong CP-problem, axions remain one of the viable candidates for the Dark Matter, although still eluding detection. Most of the methods for their detection are based on their coupling to photons, one of the most promising ones being the helioscope technique.
We will report on the current status of the CERN Axion Solar...

Millimetre-wave astronomical observations have an enormous discovery potential in the study of the earliest stages of the evolution of the universe, clusters of galaxies, high redshift objects, and star formation regions. One of the challenges today is to perform observations with the finest angular resolution, in order to accurately investigate the nature of these astrophysical sources....
