“…Finally, the count rate (𝑅) due to the radioactive source is measured. For this purpose, the output of the spectroscopic amplifier is connected to a discriminator, and the digitized signal is connected to a scaler module built in-house [14]. The value of 𝑅 at ΔV GEM = 360 V is found to be ≈ 8 kHz.…”

A quad-GEM is particularly useful for its low ion back flow, excellent rate capability, good position resolution, high gain at relatively low operating voltage in the next generation high energy physics experiments. In this work, the efficiency and uniformity of gain of a prototype quad-GEM detector are studied. A simple method is used to estimate the efficiency with the help of an oscilloscope as a triggering and storage device. An efficiency of ≈ 95% is obtained at a voltage of ΔVGEM ≥ 340 V using cosmic muons as a source. A systematic study of the uniformity of gain over the active area of the detector is done with a Fe55 X-ray source. The uniformity of gain has a spread of 11.1% over the active area of the quad-GEM detector for ΔVGEM = 360 V. The effect of gas flow rate and direction of gas flow in determining the gain are investigated for the first time for a quad-GEM detector. It is observed that different flow rates does not affect the gain uniformity significantly. However, the overall gain of the detector initially increases with the gas flow rate and starts to saturate at a higher flow rate.

The advantages of remote data acquisition (DAQ) in experimental setup are manifold. It is useful to store the time series data continuously without human intervention. Moreover, specific modification in the experimental setup for remote DAQ is also beneficial to avoid proximity to the radiation zone in the high energy physics experiments, and thus radiation exposure is minimized. In this article, a novel method of DAQ is explored for Gas Electron Multiplier (GEM) detectors employing HC-12 wireless serial communication module following both SCPI and non-standard protocols. Dedicated Laboratory Virtual Instrument Engineering Workbench (LabVIEW) based software interfacing is also developed for communication and control. As a proof of concept of the feasibility of the proposed method, the typical gain of a quad-GEM detector is estimated. Measuring instruments (a quad-scaler built in-house and a commercially procured picoammeter) are interfaced with the wireless transmission system for this purpose. Data transferred through wireless communication are utilized for estimating the normalized gain of a quad-GEM detector for a given interval of time. The details of the design of the wireless communication system, fabrication procedure, remote DAQ system, experimental arrangement, and results are presented in this article.
