window

• material
  • tedlar/mylar/tedlar from Madico
  • "We have used this type of material for spectrometer vacuum windows. It is made of high end sail cloth (actual sail material for boats). It is not the easiest material to work with but will most likely work for you. You may have to pretension the cloth depending on the manufacturer." from David Meekins of jlab target group, https://www.sailmakerssupply.com/product/racing-laminate-sailcloth-seconds/sailcloth, It's actually Kevlar/Mylar laminates
  • cheap kevlar, http://www.mcmaster.com/#kevlar/=14kwgqs , Its thickness 0.6mm is a bit bigger than 0.4mm used by BNL vacuum window, Not sure if it's because it's "cut resistant"
  • 2024 Al ~1mm thick

• test
  • testing of tedlar/mylar(3mil)/tedlar used by CLAS12 LTCC in 2016/10
    • report https://www.dropbox.com/s/f9x3o8nrm2ox4iw/report.pdf?dl=0
    • video (slow motion of bursting and fast motion of the test) http://hallaweb.jlab.org/12GeV/SoLID/download/hgc/test/16oct_test.mp4
