Lifetime Test for Optical Transmitters in the ATLAS Liquid Argon Calorimeter Readout System
Accelerated lifetime test has been carried out for 147 days on the custom-made optical transmitters used in the ATLAS Liquid Argon Calorimeter front-end electronics readout system. The lifetime of these optical transmitters is estimated to be greater than 200 years and exceeds the design goal for the LHC. The random failure rate has been estimated at 9.6×10 per hour at 90% confidence level.
متن کاملIonization of liquid argon by a particles
From an analysis of electron pulses in liquid argon produced by a particles the average energy required to form an ion pair is evaluated, assurmng JaEk’s theory of columnar recombination is valid. The mean value of 26.0 ev found in this way agrees well with the corresponding value of 26.4 ev for a particles m argon gas. Application of Jaffk’s theory to the liquid state is discussed, and from th...
متن کاملEffects of Nitrogen contamination in liquid Argon
A dedicated test of the effects of Nitrogen contamination in liquid Argon has been performed at the INFN-Gran Sasso Laboratory (LNGS, Italy) within the WArP R&D program. A detector has been designed and assembled for this specific task and connected to a system for the injection of controlled amounts of gaseous Nitrogen into the liquid Argon. Purpose of the test is to detect the reduction of th...
متن کاملThe cryogenic performances of specific optical and electrical components for a liquid argon time projection chamber
In this paper we present the cryogenic performance study of specific optical and electrical components for the Liquid Argon Time Projection Chamber (LArTPC), a potential far site detector technology of the long baseline neutrino experiment (LBNE). We have confirmed that an LVDS driver can drive a 20-meter CAT5E twisted pair up to 1 gigabit per second at liquid nitrogen temperature (77 K). We ha...
متن کاملQuality Control of Optical Transmitters for the ATLAS Liquid Argon Calorimeter
A quality control test is performed on nearly 2000 custom optical transmitters for use in the Liquid Argon Calorimeter of the ATLAS detector. More than 90% of these optical transmitters passed the test and have been installed in the calorimeter readout system. The acceptance criteria, measurement procedure, and results of the quality control test are presented in this note.
