The SIMPLE Phase II Dark Matter Search
M. Felizardo, TA Girard, T. Morlat +13
Phase II of SIMPLE (Superheated Instrument for Massive ParticLe Experiments) searched for astroparticle dark matter using superheated liquid CClF droplet detectors. Eac…
Final Analysis and Results of the Phase II SIMPLE Dark Matter Search
M. Felizardo, T. A. Girard, T. Morlat +14
We report the final results of the Phase II SIMPLE measurements, comprising two run stages of 15 superheated droplet detectors each, the second stage including an improved neutron…
SIMPLE Dark Matter Search Results
TA Girard, F. Giuliani, T. Morlat +15
We report an improved SIMPLE experiment comprising four superheated droplet detectors with a total exposure of 0.42 kgd. The result yields ~ factor 10 improvement in the previously…
New limits on WIMP interactions from the SIMPLE dark matter search
TA Girard, T. A. Morlat, M. Felizardo +3
The SIMPLE project uses superheated C2ClF5 liquid detectors to search for particle dark matter candidates. We report the results of the first stage exposure (14.1 kgd) of its lates…
First Results of the Phase II SIMPLE Dark Matter Search
M. Felizardo, T. Morlat, A. C. Fernandes +11
We report results of a 14.1 kgd measurement with 15 superheated droplet detectors of total active mass 0.208 kg, comprising the first stage of a 30 kgd Phase II experiment. In comb…
Muon tracking in a LiquidO opaque scintillator detector
LiquidO Collaboration, J. Apilluelo, L. Asquith +89
LiquidO is an innovative radiation detector concept. The core idea is to exploit stochastic light confinement in a highly scattering medium to self-segment the detector volume. In…
A CF3I-based SDD Prototype for Spin-independent Dark Matter Searches
T. Morlata, M. Felizardo, F. Giuliani +8
The application of Superheated Droplet Detectors (SDDs) to dark matter searches has so far been confined to the light nuclei refrigerants C2ClF5 and C4F10 (SIMPLE and PICASSO, resp…
COCOA: a compact Compton camera for astrophysical observation of MeV-scale gamma rays
LiquidO Collaboration, S. R. Soleti, J. J. Gómez-Cadenas +89
COCOA (COmpact COmpton cAmera) is a next-generation gamma-ray telescope designed for astrophysical observations in the MeV energy range. The detector comprises a scatterer volume e…
Neutron background signal in superheated droplet detectors of the Phase II SIMPLE dark matter search
A. C. Fernandes, A. Kling, M. Felizardo +7
The simulation of the neutron background for Phase II of the SIMPLE direct dark matter search experiment is fully reported with various improvements relative to previous estimates.…
Instrumentation, acquisition and analysis of the Phase II SIMPLE dark matter search signals
M. Felizardo
I describe the new instrumentation for the SIMPLE dark matter search experiment, and its use in identifying, validating and rejecting non-WIMP backgrounds in the first stage of the…
Fabrication and Response of High Concentration SIMPLE Superheated Droplet Detectors with Different Liquids
M. Felizardo, T. Morlat, J. G. Marques +7
The combined measurement of dark matter interactions with different superheated liquids has recently been suggested as a cross-correlation technique in identifying WIMP candidates.…
The Stochastic Light Confinement of LiquidO
LiquidO Collaboration, J. Apilluelo, L. Asquith +94
Light-based detectors have been widely used in fundamental research and industry since their inception in the 1930s. The energy particles deposit in these detectors is converted to…
