Re: [Phys-l] Gas Desorption

[Bernard Cleyet <bernardcleyet@redshift.com>]

One may also use electron and ion bombardment and plasma cleaning.  In 
the case of plasma cleaning it's important to use aluminium electrode(s) 
to prevent sputtering.

bc, who once cleaned glass using an ancient method (chromic / sulphuric 
acid).  Also, substrates w/ electron bombardment and plasma, and just 
heat w/ a Varian oilless UHV system.
