“…The reflection of Si in the UV limits the overall QE of the detectors, and so a custom 3-layer anti-reflection coating was developed to reduce reflection in the FIREBall bandpass. 22,[29][30][31][32] Measured QE is shown in Figure 4 The detector performance was verified via testing at JPL and at Caltech. JPL testing included QE verification, 33 while the Caltech test set-up measured QE at limited wavelengths using NUVU v2 and v3 CCCP controllers 34 and a custom flight printed circuit board (PCB).…”

Here we discuss advances in UV technology over the last decade, with an emphasis on photon counting, low noise, high efficiency detectors in sub-orbital programs. We focus on the use of innovative UV detectors in a NASA astrophysics balloon telescope, FIREBall-2, which successfully flew in the Fall of 2018. The FIREBall-2 telescope is designed to make observations of distant galaxies to understand more about how they evolve by looking for diffuse hydrogen in the galactic halo. The payload utilizes a 1.0-meter class telescope with an ultraviolet multiobject spectrograph and is a joint collaboration between Caltech, JPL, LAM, CNES, Columbia, the University of Arizona, and NASA. The improved detector technology that was tested on FIREBall-2 can be applied to any UV mission. We discuss the results of the flight and detector performance. We will also discuss the utility of sub-orbital platforms (both balloon payloads and rockets) for testing new technologies and proof-of-concept scientific ideas.

“…Not only will this work on charge integrating CCDs and CMOS devices, but also other silicon technologies that offer potential photoncounting capabilities such as avalanche photodiode (APD) arrays and electron multiplying CCDs (EMCCD). Surface treated EMCCDs will soon be launching on the sub-orbital rocket mission "CHESS" (Hoadley et al 2014) and the FIREBALL-2 balloon payload (Hamden et al 2014).…”

We present the science cases and technological discussions that came from the workshop entitled "Finding the UV-Visible Path Forward" held at NASA GSFC June 25-26, 2015. The material presented outlines the compelling science that can be enabled by a next generation space-based observatory dedicated for UV-visible science, the technologies that are available to include in that observatory design, and the range of possible alternative launch approaches that could also enable some of the science. The recommendations to the Cosmic Origins Program Analysis Group from the workshop attendees on possible future development directions are outlined.

“…More details about the high QE of the detector can be found in other papers by our group. 4 Our expected QE of ∼70% is a significant increase over the GALEX MCP. More recent MCPs since the GALEX flight have achieved higher QE (around 20 percent in the FIREBall band 21 ), but a delta-doped AR-coated EMCCD still has an advantage in QE.…”

The Faint Intergalactic-medium Redshifted Emission Balloon (FIREBall-2) is an experiment designed to observe low density emission from HI, CIV, and OVI in the circum-galactic medium around low-redshift galaxies. To detect this diffuse emission, we use a high-efficiency photon-counting EMCCD as part of FIREBall-2's detector. The flight camera system includes a custom printed circuit board, a mechanical cryo-cooler, zeolite and charcoal getters, and a Nüvü controller, for fast read-out speeds and waveform shaping. Here we report on overall detector system performance, including pressure and temperature stability. We describe dark current and CIC measurements at several temperatures and substrate voltages, with the flight set-up.
