Abstract:
LIGO Vacuum Compatible Materials List
Authors:
Keywords:
UHV materials
Notes and Changes:
1) Added permalloy MuMetals (i.e. nickel-iron-molybdenum alloys) which is an inherently vacuum compatible material if wrought (not cast)
2) Clarified that 450G, 450GL, 450CA and 450U grades of PEEK are all allowable, but restricted (all polymers are restricted)
3) Added PEEK ESD 480 (for use as the A-OSEM head)
