TL;DR
This paper investigates how cosmic rays impact cryogenic high-sensitivity detectors, using the DRACuLA facility to test new detector generations after the Planck mission.
Contribution
It introduces the DRACuLA facility and presents new experimental results on detector susceptibility to cosmic rays.
Findings
Cosmic rays significantly affect cryogenic detectors, requiring post-processing.
New detector generations show varying susceptibility to cosmic ray impacts.
Results inform future design of space-based cryogenic detectors.
Abstract
After the Planck mission's launch in 2009, bolometers of its High Frequency Instrument (HFI) were considerably affected by cosmic rays, which necessitated several years of post-treatment to clean the data. To study the susceptibility of high sensitivity cryogenic detectors to particle impacts, IAS has developed the DRACuLA facility. We present the results of the latest two test campaigns performed on new generation of detectors.
