We use MIKDs as single photon detectors by measuring the arrival time of incoming photons with an accuracy of a few microseconds and with a relatively high energy resolution (R~10 at 1um). We fabricate kilopixels array of MKIDs and we incorporate them in our own instruments for UVOIR astronomy with the main application being exoplanets direct imaging.\u0000We present the work being made in our lab in the development and fabrication of 10 to 20k pixels arrays for the DARKNESS (Dark-speckle Near-IR Energy-resolved Superconducting Spectrophotometer) and MEC (MKID Exoplanet Camera) instruments, respectively. The 6-step fabrication process has been upgraded over the last months in order to improve the sensitivity of the arrays. The detectors are made of platinum silicide (PtSi) since MKIDs with very high internal quality factor have been successfully fabricated from this material. Furthermore, PtSi with very uniform superconducting properties over 4inch substrate are much more easier to deposit than the regular TiN used in most existing MKIDs technology. Among various upgrades, we coated the PtSi sensitive area with a SiO2/Ta2O5 bi-layer in order to reduce the reflection of optical photons hitting the detectors. The light absorption is increased by a factor of 2 in the instruments bandwidth. The DARKNESS instrument has been successfully commissioned last summer and MEC, the world largest superconducting camera, is installed at the Subaru telescope since the beginning of the year. Our effort leads to the fabrication of arrays of detectors with a median internal quality factor of 100 000 with an energy resolution of 10 at 1um and a pixel yield approaching 95%.\u0000 In addition, we will present new MKID design in which the conventional meander inductor and interdigitated capacitor are replaced by a square inductor and a large parallel plate capacitor made of two metal plates separated by a ~10-nm thick dielectric layer. This parallel plate design allows us to drive the MKIDs at a higher power, which in turns should increase the sensitivity of the detectors. Following promising results from our first design, second generation of parallel plate MKID devices have been made from Hf/HfO2/Nb tri-layers deposited in-sit. We obtained high quality factor from the parallel plate MKIDs and we were able to detect photons with this new MKIDs design. Another way to improve the sensitivity of MKIDs is to use a low Tc material, compared to Tc ~ 1K usually used. We fabricated MKIDs arrays with superconducting Hafnium, Tc = 450mK, and we demonstrated that resonators with very high internal quality factors Qi~300 000 and an energy resolution of 9 at 808nm can be achieved.","PeriodicalId":359588,"journal":{"name":"High Energy, Optical, and Infrared Detectors for Astronomy VIII","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126904286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The coronagraph is designed to directly image planets around nearby stars, and to characterize their spectra. The planets are exceedingly faint, providing signals similar to the detector dark current, and require the use of photon counting detectors. Red sensitivity (600-980nm) is preferred to capture spectral features of interest. EMCCDs are baselined both as science and wavefront sensors in the coronagraph in order to simplify the system architecture. We are engaged in a test program to characterize the performance of the EMCCD in the required modes, as well as in a technology development program with Teledyne-e2v to ruggedize the sensors for use in space.

The spacecraft’s 10 scientific instruments, including a high resolution optical imager called JANUS, will explorer the Jovian system for a mission duration of 3 years studying the icy surfaces of Ganymede, Callisto and Europa and atmosphere of Jupiter. Using the combination of a 13 slot filter wheel and a back-illuminated CMOS image sensor, the JANUS camera will perform colour mapping and imaging at wavelengths between 350 nm and 1064 nm and resolutions of up to 10 m/pixel resolution during a Ganymede orbital phase.\u0000\u0000The CIS115 is a rolling shutter image sensor from Teledyne-e2v that has been selected for JANUS. It is back-illuminated and anti-reflection coated in order to optimise detection efficiency in its 3 MPixel imaging area. Its 4T architecture reduces the dark current in the pinned photodiode collecting area to approximately 13 pA/cm^2 at 20˚C and allows the device to be operated with correlated double sampling for a readout noise performance of 5 electrons rms. In preparation for its use in JANUS, the CIS115 has undergone a thorough qualification programme, including exposure to ionising and non-ionising radiation levels of up to 200 krad(Si) and 2x10^10 protons/cm^2 (10 MeV equivalent), and a single event effect test campaign.\u0000\u0000The CIS115 device qualification is now complete and results from the radiation test campaigns are being used to predict the expected performance at various phases of the mission as radiation damage is accumulated in the sensor. Dark current is the primary performance characteristic that has been observed to degrade with irradiation, and predicting the device’s performance at the end of life allows the maximum operating temperature of the detector to be set and justified. Additionally, behaviour observed during the qualification testing has led to optimised readout schemes that reduce the device image lag performance across the dynamic range to below the 0.1% level.","PeriodicalId":359588,"journal":{"name":"High Energy, Optical, and Infrared Detectors for Astronomy VIII","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121926982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mission will study the dynamic interaction between the solar wind and the Earth’s magnetosphere. Two of the instruments, namely the Soft X-ray Imager (SXI) and the Ultra-Violet Imager (UVI), will observe northern aurora and the boundary of the magnetosphere simultaneously, a first for space-missions. To complement these remote observations, in-situ measurements of the solar wind ion distribution as well as measurements of the strength of magnetic fields will be attained via the Light Ion Analyser (LIA) and the Magnetometer (MAG) respectively. Together, these four instruments will provide a complete picture of the interactions between the solar wind and the response of the Earth’s magnetosphere, which is the main driver of space-weather.\u0000The SXI will be used to observe and image Solar Wind Charge eXchange (SWCX) that occurs at the interface between the solar wind and the Earth’s magnetosphere. At this location, ions in the solar wind interact with neutrals in the Earth’s exosphere leading to the production of soft X-rays with key emission lines at energies between 0.1-2 keV. The SXI will use a wide angle silicon micro pore optic to focus the incoming X-rays onto a focal plane of two large area Charge-Coupled Devices (CCDs) from Teledyne-e2v.\u0000The CCD for SXI is designated the CCD370, with 4510x4510 pixels of 18 µm, which will be read out with 6x6 on-chip binning to give an effective pixel size of 108 µm square. The binning improves charge transfer efficiency and energy resolution, and allows the pixel area to be divided into asymmetric frame and store regions of the device for frame-transfer operation. The CCD370 design includes a range of modifications from its predecessor (the CCD270 from the PLATO mission), with the goal of optimising it for imaging soft X-rays; a supplementary buried channel in the parallel region, a narrowed serial channel width, and increased output amplifier responsivity will improve the low signal sensitivity and charge transfer efficiency.\u0000Here, the CCD370 performance in the SXI telescope will be presented, predicted from the first measurements using the laboratory SXI CCD characterisation camera and CCD270s. The improvements expected from design changes that optimise the SXI CCDs for soft X-ray detection, and plans for pre-flight calibration and radiation damage testing will be described.","PeriodicalId":359588,"journal":{"name":"High Energy, Optical, and Infrared Detectors for Astronomy VIII","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133395398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Signal is varied by parallel-binning a successively greater number of lines. The binned image is compared to a conventional image with identical illumination, co-added digitally in the same pattern. This method requires no shutter calibration and is insensitive to illumination drift or charge transfer inefficiency. With some additional software effort, it can be arranged to tolerate illumination non-uniformity. We present data obtained by both methods for the 64 CD231-C6 outputs and discuss automated performance optimization. We find that the widely held assumption that non-linearity only affects high signals is incorrect when optimizing for minimum gain change over the full signal range, in which case slope increases with signal initially, then peaks in the mid-range before dropping again.","PeriodicalId":359588,"journal":{"name":"High Energy, Optical, and Infrared Detectors for Astronomy VIII","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116895673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
