Argon-37 is an environmental signature of an underground nuclear explosion. Producing and quantifying low-level Ar-37 standards is an important step in the development of sensitive field measurement instruments. This paper describes progress at Pacific Northwest National Laboratory in developing a process to generate and quantify low-level Ar-37 standards, which can be used to calibrate sensitive field systems at activities consistent with soil background levels. This paper presents a discussion of the measurement analysis, along with assumptions and uncertainty estimates.

The energy deposition spectra of $^{37}$Ar and $^{71}$Ge in a miniature proportional counter are measured and compared in detail to the model response simulated with Geant4. A certain modification of the Geant4 code, making it possible to trace the d eexcitation of atomic shells properly, is suggested. Modified Geant4 is able to reproduce a response of particle detectors in detail in the keV energy range. This feature is very important for the laboratory experiments that search for massive sterile neutrinos as well as for dark matter searches that employ direct detection of recoil nuclei. This work demonstrates the reliability of Geant4 simulation at low energies.
We have experimentally determined the production rate of $^{39}$Ar and $^{37}$Ar from cosmic ray neutron interactions in argon at sea level. Understanding these production rates is important for argon-based dark matter experiments that plan to utiliz e argon extracted from deep underground because it is imperative to know what the ingrowth of $^{39}$Ar will be during the production, transport, and storage of the underground argon. These measurements also allow for the prediction of $^{39}$Ar and $^{37}$Ar concentrations in the atmosphere which can be used to determine the presence of other sources of these isotopes. Through controlled irradiation with a neutron beam that mimics the cosmic ray neutron spectrum, followed by direct counting of $^{39}$Ar and $^{37}$Ar decays with sensitive ultra-low background proportional counters, we determined that the production rate from cosmic ray neutrons at sea-level is expected to be $(759 pm 128)$ atoms/kg$_text{Ar}$/day for $^{39}$Ar, and $(51.0 pm 7.4)$ atoms/kg$_text{Ar}$/day for $^{37}$Ar. We also performed a survey of the alternate production mechanisms based on the state-of-knowledge of the associated cross-sections to obtain a total sea-level cosmic ray production rate of $(1048 pm 133)$ atoms/kg$_text{Ar}$/day for $^{39}$Ar, $(56.7 pm 7.5)$ atoms/kg$_text{Ar}$/day for $^{37}$Ar in underground argon, and $(92 pm 13)$ atoms/kg$_text{Ar}$/day for $^{37}$Ar in atmospheric argon.
An active device for radon detection in the air was developed. The monitor operates in pulse counting mode for real-time continuous measurements. The presented prototype has a relatively simple design made of low-price and easy to acquire components which made it possible to develop an inexpensive device. The device used as a sensor, the SLCD-61N5 Si-PIN planar photodiode, which has an area of 9.67x9.67 mm2, is sensitive to alpha particles. An Arduino Uno microcontroller was used as a data acquisition system. Signals were observed when placing an 241Am or 226Ra source near the sensor. The sensors sensitivity has small bias dependency and the device can operate even at modest voltage. As a result of a one-month test in a radon-rich atmosphere, a positive high correlation (Pearsons r equal to 0.977) was obtained between our prototype and a Geiger-Muller detector.

We developed a low-mass and high-efficiency charged particle detector for an experimental study of the rare decay $K_L rightarrow pi^0 u bar{ u}$. The detector is important to suppress the background with charged particles to the level below the sig nal branching ratio predicted by the Standard Model (O(10$^{-11}$)). The detector consists of two layers of 3-mm-thick plastic scintillators with wavelength shifting fibers embedded and Multi Pixel Photon Counters for readout. We manufactured the counter and evaluated the performance such as light yield, timing resolution, and efficiency. With this design, we achieved the inefficiency per layer against penetrating charged particles to be less than $1.5 times 10^{-5}$, which satisfies the requirement of the KOTO experiment determined from simulation studies.
We present our latest ASIC, which is used for the readout of Cadmium Telluride double-sided strip detectors (CdTe DSDs) and high spectroscopic imaging. It is implemented in a 0.35 um CMOS technology (X-Fab XH035), consists of 64 readout channels, and has a function that performs simultaneous AD conversion for each channel. The equivalent noise charge of 54.9 e- +/- 11.3 e- (rms) is measured without connecting the ASIC to any detectors. From the spectroscopy measurements using a CdTe single-sided strip detector, the energy resolution of 1.12 keV (FWHM) is obtained at 13.9 keV, and photons within the energy from 6.4 keV to 122.1 keV are detected. Based on the experimental results, we propose a new low-noise readout architecture making use of a slew-rate limited mode at the shaper followed by a peak detector circuit.
