Universidad de Zaragoza (orcid)0000-0002-6948-5101 Erratum: Micromegas-TPC operation at high pressure in xenon-trimethylamine mixtures (Journal of Instrumentation (2013) 8 (P01012)) 2015 Access copy available to the general public Unrestricted During the investigations performed after the publication of the original article, a mistake in the calibration procedure was revealed, resulting in a 50% relative increase of the estimate of the concentration of trimethylamine (TMA) in the mixtures employed. In this erratum we provide the correct concentrations after a careful re-evaluation, and therefore the statistical and systematic uncertainties are now included. The calibration procedure was performed by pre-mixing TMA with Xenon for known concentrations of the former in the range 0.5% to 50%. Several external conditions were altered, like the time before sampling and the time required for proper mixing (done with a recirculation pump), yielding deviations of about 10%. The overall statistical uncertainty was obtained from the one derived for the calibration factor, once combined with the statistical uncertainty in the estimate of the most prominent peaks of the involved species: TMA(A = 59) and Xe(A = 132), illustrated in figure 1. Generally, where it had been previously stated that the optimum for operation of Micromegas (i.e., maximum Penning transfer before excessive electron cooling) corresponded to about 1:5%TMA admixture, it should be modified to ~1%TMA after this revision.
