At present, application of Superheated Droplet Detectors (SDDs) in WIMP dark matter searches has been limited to the spin-dependent sector, owing to the general use of fluorinated refrigerants which have high spin sensitivity. Given their recent demonstration of a significant constraint capability with relatively small exposures and the relative economy of the technique, we consider the potential impact of heavy versions of such devices on the spin-independent sector. Limits obtainable from a ${\mathrm{CF}}_{3}\mathrm{I}$-loaded SDD are estimated on the basis of the radiopurity levels and backgrounds already achieved by the SIMPLE and PICASSO experiments. With 34 kgd exposure, equivalent to the current CDMS, such a device may already probe to below ${10}^{\ensuremath{-}6}\text{ }\text{ }\mathrm{pb}$ in the spin-independent cross section.

Effects of the Generic Masculine and its Alternatives in Germanophone countries - A Multi-lab Replication and Extension of Stahlberg, Sczesny, and Braun, 2001

Hilmar Brohmer Gabriela Hofer Sebastian A. Bauch Julia Beitner Jana B. Berkessel

In languages such as German, French, or Hindi, plural forms of job occupations and societal roles are often in a generic-masculine form instead of a gender-inclusive form. Although meant as “generic”, this generic-masculine form excludes women from everyday language. Specifically, listeners and readers are less likely to think of women when this form is used. Due to the societal relevance of gender-inclusive language, we directly replicated and extended a classic study by Stahlberg, Sczesny, and Braun (2001, Experiment 2) in a multi-lab setting and as a registered confirmatory report. We prompted participants from German-speaking countries to name up to three celebrities each in six categories (e.g., “Name three politicians” or “(...) singers”). We then counted how often participants mentioned women. Participants were either prompted with the generic-masculine form, a neutralized control form or one out of three gender-inclusive forms. Our data from twelve labs and N = 2,697 participants replicated the original effect: when prompted with gender-inclusive forms participants mentioned more women than when the generic masculine and the control form were used. Moreover, the effect remained present in multilevel models and when controlling for participants’ sex and their perceived base rate in these celebrity categories (i.e., the expected proportion of women). Other variables, such as political orientation or preference for gender-inclusive language, did not show large effects, either. We discuss the differences between specific gender-inclusive forms (e.g., the internal-I vs. feminine-masculine forms), implications for regulations and guidelines, as well as implications for non-binary and gender-diverse people.

Neutron spectrometry with large volume, heavy-loaded superheated droplet detectors: a simple spin-off

Radiation Protection Dosimetry (2005)

A.R. Ramos F. Giuliani M. Felizardo T. A. Girard T. Morlat

SIMPLE is a superheated droplet detector (SDD) experiment designed to search for the evidence of spin-dependent weakly interacting neutralino dark matter (WIMPs). SDDs, a type of emulsion detector, consist of a uniform suspension of superheated liquid droplets in a compliant material such as a polymeric or aqueous gel. We report on the first neutron spectrometry experiments with SIMPLE SDDs, a spin-off of the neutron detector calibrations performed at the Portuguese Research Reactor. SIMPLE SDDs differ from most SDDs available commercially as they have a 10 times higher loading factor, containing 103 times more freon than their commercial counterparts and a 100 times larger volume. We have analysed the response of SIMPLE SDDs to two quasi-monochromatic neutron beams of energies 54 and 144 keV obtained with passive filters. Results show that the characteristic peaks in the fluence distribution of both filters could be determined and their energy position obtained using a simple thermodynamic relation.

Impact of a ’’heavy’’ SIMPLE on the search for WIMP dark matter

Journal of Physics Conference Series (2006)

F. Giuliani T. Morlat T. A. Girard M. Felizardo J.G. Marques

We examine the potential impact of a WIMP search based on CF3I-loaded SDDs, projected on the basis of the experience and results of the SIMPLE dark matter search. We find such a ''heavy'' SIMPLE experiment to have spin-independent sensitivity comparable to that of leading searches like ZEPLIN-I and CDMS, while preserving the spin-dependent sensitivity of fluorine-based experiments.

BambooMC — A Geant4-based simulation program for the PandaX experiments

Journal of Instrumentation (2021)

Xun Chen C. H. Cheng Mengting Fu F. Giuliani Jun Liu

The purpose of the PandaX experiments is to search for the possible events resulted from dark matter particles, neutrinoless double beta decay or other rare processes with xenon detectors. Understanding the energy depositions from backgrounds or calibration sources in these detectors is very important. The program of BambooMC is created to perform the Geant4-based Monte Carlo simulation, providing reference information for the experiments. We introduce the design and features of BambooMC in this report. The running of the program depends on a configuration file, which combines different detectors, event generators, physics lists and analysis packs together in one simulation. The program can be easily extended and applied to other experiments.
