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
  • test 0: Test of 1.5mil Tedlar/3 mil PET/1.5 mil Tedlar material obtained from CLAS LTCC. with video showing slow motion of bursting and fast motion of the test
  • test 1: Full size test of 5 mil Mylar/12 mil Kevlar window material. Dec 5, 2016.
  • test 2: Full size test of 5 mil Mylar/12 mil Kevlar window with circumferential epoxy. Feb 16, 2017.
  • test 3: Small size test of double layer 5 mil Mylar/12 mil Kevlar window with epoxy coating. June 9, 2017.
  • test 4: Small size tests of five different configurations of 5 mil Mylar/12 mil Kevlar window with epoxy coating. Aug 16, 2017.
