X-ray Response of the Fully-Depleted, p-Channel SiSeRO-CCD
Julian Cuevas-Zepeda, Joseph Noonan, Claudio Chavez +6
We present an X-ray characterization of a fully depleted, 725 m thick p-channel SiSeRO-CCD. Measurements with a Fe source yield an energy resolution of eV ($…
A compact, low-power epithermal neutron counter for lunar water detection
Julian Cuevas-Zepeda, Phoenix Alpine, Brenda A. Cervantes-Vergara +7
The detection and characterization of lunar water are critical for enabling sustainable human and robotic exploration of the Moon. Orbital neutron spectrometers, such as instrument…
Characterization of proton-induced damage in thick, p-channel skipper-CCDs
Brenda A. Cervantes-Vergara, Santiago E. Perez, Claudio R. Chavez +4
In this work, we characterize the radiation-induced damage in two thick, p-channel skipper-CCDs irradiated unbiased and at room temperature with 217-MeV protons. We evaluate the ov…
Skipper-CCD Sensors for the Oscura Experiment: Requirements and Preliminary Tests
Brenda A. Cervantes-Vergara, Santiago Perez, Juan Estrada +52
Oscura is a proposed multi-kg skipper-CCD experiment designed for a dark matter (DM) direct detection search that will reach unprecedented sensitivity to sub-GeV DM-electron intera…
First results from a multiplexed and massive instrument with sub-electron noise Skipper-CCDs
F. Chierchie, C. R. Chavez, M. Sofo Haro +7
We present a new instrument composed of a large number of sub-electron noise Skipper-CCDs operated with a two stage analog multiplexed readout scheme suitable for scaling to thousa…
Analog pile-up circuit technique using a single capacitor for the readout of Skipper-CCD detectors
Miguel Sofo Haro, Claudio Chavez, Jose Lipovetzky +8
With Skipper-CCD detectors it is possible to take multiple samples of the charge packet collected on each pixel. After averaging the samples, the noise can be extremely reduced all…
