Dr Aritoki Suzuki (UCB)
I will give overview of a focal plane unit proposed by the US LiteBIRD team. The focal plane unit consists of sub-kelvin cooler, transition edge sensor bolometric detector, readout electronics, and mechanical supports. The baseline design is based on proven technologies from current ground and balloon based CMB experiments lead by member of the US LiteBIRD team. Space environment and...
Dr Guillaume Patanchon (APC)
The Planck satellite mission allowed to map the Cosmic MicrowaveBackground anisotropies and polarization on the full sky withunprecedented accuracy. The precision of the measurements was reachedthanks to the thermal stability of the instruments which includePolarization Sensitive Bolometers cooled down to 100 mK for the HighFrequency Instrument, but required carefull processing of...
43. Development and Fabrication of the Lenslet Coupled Sinuous Antenna TES Bolometer Arrays for the LiteBIRD Low and Mid Frequency Focal planes Ben Westbrook (UCB)
Dr Ben Westbrook
We discuss one of the two candidate detector technologies for the LiteBIRD satellite mission: lenslet-coupled sinuous antenna transition edge sensor (TES) detector arrays. We discuss the current status and future challenges for the design, fabrication, and characterization of this technology for the LiteBIRD low and mid frequency (LF and MF, respectively) focal planes. These design of...
Dr Hannes Hubmayr (NIST)
I will discuss technology developed and fabricated at NIST that is relevant to the LiteBIRD satellite mission. This includes feedhorn-coupled, transition-edge-sensor (TES) polarimeter arrays, which are the baseline focal plane technology of the high frequency telescope as proposed in the US-contribution to the mission. Developed in collaboration with a large fraction of the US CMB community,...
Mr Ari Cukierman (UCB)
The design of the LiteBIRD focal planes needs to balance cryogenic, mechanical, optical and electrical concerns. I will discuss the cryogenic and mechanical issues associated with these technologies with special emphasis on the unique challenges and uncertainties present in a space-based environment. Additionally, I will summarize baseline technologies and the requirements for the LiteBIRD...
Dr Matt Dobbs (McGill)
The Digital Frequency Domain Multiplexing Bolometer Readout system is the baseline design for LiteBIRD. The overall system will be presented, with a focus on the warm electronics. The cold components will be described in the following talk. Results and status from Canadian-funded flight representative circuit board development will be overviewed.Key interface points, power consumption, and...
Dr Kam Arnold (Wisconsin)
will present the baseline architecture for all of the electrical components between the LiteBIRD detector wafers and the warm readout electronics. This baseline architecture is based on the requirements of the frequency domain multiplexing bolometer readout, which will be discussed by Professor Dobbs in the previous presentation. I will discuss the requirements that still need to be determined...
