Light-tight skipper-CCDs for X-ray detection in space
Ana M. Botti, Yikai Wu, Brenda Cervantes +6
Skipper Charge-Coupled Devices (skipper-CCDs) are pixelated silicon detectors with deep sub-electron resolution. Their radiation hardness and capability to reconstruct energy depos…
Readout Optimization of Multi-Amplifier Sensing Charge-Coupled Devices for Single-Quantum Measurement
Ana M. Botti, Brenda A. Cervantes-Vergara, Claudio R. Chavez +15
The non-destructive readout capability of the Skipper Charge Coupled Device (CCD) has been demonstrated to reduce the noise limitation of conventional silicon devices to levels tha…
Astronomical Spectroscopy with Skipper CCDs: First Results from a Skipper CCD Focal Plane Prototype at SIFS
Edgar Marrufo Villalpando, Alex Drlica-Wagner, Brandon Roach +22
We present the first on-sky results from an ultra-low-readout-noise Skipper CCD focal plane prototype for the SOAR Integral Field Spectrograph (SIFS). The Skipper CCD focal plane c…
Sixteen Multiple-Amplifier Sensing Charge-Coupled Devices and Characterization Techniques Targeting the Next Generation of Astronomical Instruments
Agustin J. Lapi, Blas J. Irigoyen Gimenez, Miqueas E. Gamero +8
We present a candidate sensor for future spectroscopic applications, such as a Stage-5 Spectroscopic Survey Experiment or the Habitable Worlds Observatory. This type of charge-coup…
Characterization and Optimization of Skipper CCDs for the SOAR Integral Field Spectrograph
Edgar Marrufo Villalpando, Alex Drlica-Wagner, Andrés A. Plazas Malagón +14
We present results from the characterization and optimization of six Skipper CCDs for use in a prototype focal plane for the SOAR Integral Field Spectrograph (SIFS). We tested eigh…
Achieving Single-Electron Sensitivity at Enhanced Speed in Fully-Depleted CCDs with Double-Gate MOSFETs
Miguel Sofo-Haro, Kevan Donlon, Juan Estrada +3
We introduce a new output amplifier for fully-depleted thick p-channel CCDs based on double-gate MOSFETs. The charge amplifier is an n-type MOSFET specifically designed and operate…
Fast Single-Quantum Measurement with a Multi-Amplifier Sensing Charge-Coupled Device
Ana M. Botti, Brenda A. Cervantes-Vergara, Claudio R. Chavez +11
A novel readout architecture that uses multiple non-destructive floating-gate amplifiers to achieve sub-electron readout noise in a thick, fully-depleted silicon detector is presen…
