| Outline of Annual Research Achievements |
The main part of the work in FY2015 has been to build the high speed high sensitivity MKIDs camera optimized for exoplanet imaging. During FY2015, the key MKIDs camera parts were built and are now ready for final assembly. The electronics boards to read the camera images have been designed and manufacturing: at the end of FY2015, they are ready for testing. The cooling architecture for the electronics has been designed and manufactured.
During FY2015, the team has also redesigned part of the existing Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) system to feed light to the MKIDs camera. With this new design, the SCExAO system will use the MKIDs camera for imaging exoplanets never seen before.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
MKIDs camera development (Achieved as planned)-The camera is under final assembly at the University of California Santa Barbara, with a delivery to Subaru Telescope scheduled in Jan 2017. Algorithms and software to combine the camera with the SCExAO instrument are already well underway.
Coronagraph Development (A little Delayed)-New coronagraph designs have been developed offering increased performance. Manufacturing has been delayed by unexpected manufacturing issues. We are seeking alternate vendors to proceed.
Plans for TMT instrument (Higher than planned at the beginning of the project)-Our hardware development is compatible with our TMT instrument goal. We have designed coronagraph solutions for the TMT; have identified that high resolution spectroscopy will provide additional means to separate planet light and residual starlight and detect water and oxygen.
|
| Strategy for Future Research Activity |
The MKIDs camera will be integrated with the SCExAO system on the Subaru Tele-scope. Optics and mechanics on the SCExAO bench will be upgraded to adapt to the MKIDs camera. The SCExAO team will work closely with the UCSB team to integrate the MKIDs camera within the SCExAO wavefront control system: images acquired by the camera will be used in coordination with the existing deformable mirror to measure and control residual starlight. The speckle control algorithm that cancels residual star-light will run at kHz speed in coordination with other sensors in the system (visible light Pyramid wavefront sensor and near-IR coronagraphic low-order sensor).
On-sky observations will start during the fiscal year FY2016.
