“…This is highly motivated especially in dark matter searches where light yield directly effects the sensitivity and background rejection capabilities. The proposed 300 tonne Global Argon Dark Matter Collaboration detector (GADMC) [1], based on a scaled-up single- [2] or dual-phase [3] approach, is capable of reaching the "neutrino floor", i.e. the ultimate sensitivity at which the interactions from coherent a e-mail: mkuzniak@physics.carleton.ca elastic neutrino-nucleus scattering become the limiting background.…”

Polyethylene naphthalate film as a wavelength shifter in liquid argon detectors

Liquid argon-based scintillation detectors are important for dark matter searches and neutrino physics. Argon scintillation light is in the vacuum ultraviolet region, making it hard to be detected by conventional means. Polyethylene naphthalate (PEN), an optically transparent thermoplastic polyester commercially available as large area sheets or rolls, is proposed as an alternative wavelength shifter to the commonly-used tetraphenyl butadiene (TPB). By combining the existing literature data and spectrometer measurements relative to TPB, we conclude that the fluorescence yield and timing of both materials may be very close. The evidence collected suggests that PEN is a suitable replacement for TPB in liquid argon neutrino detectors, and is also a promising candidate for dark matter detectors. Advantages of PEN are discussed in the context of scaling-up existing technologies to the next generation of very large ktonne-scale detectors. Its simplicity has a potential to facilitate such scale-ups, revolutionizing the field.

“…Light in this wavelength range would be strongly absorbed by most detector materials. Tetraphenyl butadiene (TPB) is among one of the favorite WLS options [1][2][3] in a number of neutrino and dark matter experiments using liquid argon, such as Mi-croBooNE [4], DUNE [5], DEAP-3600 [6,7], DarkSide-20k [8] and ArDM [9], which absorbs UV light and re-emit lights in visible spectrum to be easily and effectively detected by photomultipliers tubes (PMT) or Silicon Photomultipliers (SiPM). WLS is also used in Cherenkov detectors to improve light yield [10][11][12].…”

Scintillation light from liquid noble gas in a neutrino or dark matter experiment lies typically within the vacuum ultraviolet (VUV) region and might be strongly absorbed by surrounding materials such as light guides or photomultipliers. Tetraphenyl butadiene (TPB) is a fluorescent material and acts as a wavelength shifter (WLS) which can turn the UV light to the visible light around a peak wavelength of 425 nm, enabling the light signals to be detected easily for physics study. Compared with a traditional TPB coating method using vapor deposition, we propose an alternative technique with a spin coating procedure in order to facilitate the development of neutrino and dark matter detectors. This article introduces how to fabricate the TPB film on acrylics using the spin coating method, reports measurement of sample film thickness and roughness, shows the reemission spectrum, and quantifies the wavelength shifting efficiency (WLSE).

The DEAP-3600 detector searches for dark matter interactions on a 3.3 tonne liquid argon target. Over nearly a decade, from start of detector construction through the end of the data analysis phase, well over 200 scientists will have contributed to the project. The DEAP-3600 detector will amass in excess of 900 TB of data representing more than 10 10 particle interactions, a few of which could be from dark matter. At the same time, metadata exceeding 80 GB will be generated. This metadata is crucial for organizing and interpreting the dark matter search data and contains both structured and unstructured information.The scale of the data collected, the important role of metadata in interpreting it, the number of people involved, and the long lifetime of the project necessitate an industrialized approach to metadata management.We describe how the CouchDB and the Post-greSQL database systems were integrated into the DEAP detector operation and analysis workflows. This integration provides unified, distributed access to both structured (PostgreSQL) and unstructured (CouchDB) metadata at runtime of the data analysis software. It also supports operational and reporting requirements.
