Ultrasonic welding technology for straw trackers: from development to application
DOI:
https://doi.org/10.63907/ansa.v1i3.52Abstract
This article provides a comprehensive description of the straw production technology developed and refined at the Laboratory of High Energy Physics of the Joint Institute for Nuclear Research (JINR, Dubna), as well as its subsequent evolution at both JINR and the Institute of Nuclear Physics (INP, Almaty). It outlines all stages of the ultrasonic welding (USW) process and compares the properties of glued, wound, and welded straws, with particular emphasis on their mechanical stability. The successful operation of a Straw Tracker made from USW straws in the NA62 experiment at CERN highlights the advantages of this technology and underscores its relevance for experiments such as COMET, SHiP, DUNE, and SPD.
