“…The red curve and band in the bottom panels are the global fit of world data, in LAr data from Ref. [29,[45][46][47][48][49][50][51][52][53][54][55][56][57][58], GAr data from Ref. [33][34][35][36][37][38][39][40][41][42][43][44].…”

We report the measurement of longitudinal electron diffusion coefficients in liquid argon for electric fields between 100 and 2000 V/cm with a gold photocathode as a bright electron source. The measurement principle, apparatus, and data analysis are described. In the region between 100 and 350 V/cm, our results show a discrepancy with the previous measurement [1]. In the region between 350 and 2000 V/cm, our results represent the world's best measurement. Over the entire measured electric field range, our results are systematically higher than the calculation of Atrazhev-Timoshkin [2]. The quantum efficiency of the gold photocathode, the drift velocity and longitudinal diffusion coefficients in gas argon are also presented.

“…It has to be noted that Eq. 3.1 and 3.3 are valid only for a grid of equally spaced parallel wires [14,15]. The TPC can be positioned inside the vessel in two different orientations: with the electrodes parallel to the ground for a vertical drift (figure 7), and with the electrodes orthogonal to the ground for a horizontal drift (figure 9).…”

A prototype liquid Argon Time Projection Chamber for the study of UV laser multi-photonic ionization

This paper describes the design, realization and operation of a prototype liquid Argon Time Projection Chamber (LAr TPC) detector dedicated to the development of a novel online monitoring and calibration system exploiting UV laser beams. In particular, the system is intended to measure the lifetime of the primary ionization in LAr, in turn related to the LAr purity level. This technique could be exploited by present and next generation large mass LAr TPCs for which monitoring of the performance and calibration plays an important role. Results from the first measurements are presented together with some considerations and outlook.

“…The k j are directly proportional to the number densities n j of the corresponding kind of impurities. A rule of thumb relating the level of oxygen equivalent impurities to the characteristic time constant τ (often named the 'charge lifetime' in this context) is given by [49] at t = 0 here.…”
