@lgray and @fratnikov - this is a complete to a new Phase II beampipe.

@ianna Just to make sure I understand this includes the double thickness Al-2219 beampipe + beampipe taper fix

How should we handle the AlBeMet version, make two separate PRs and study both? To my understanding the geometry was basically taking present beampipe geometry and replacing stainless steel with AlBeMet (except with aluminum bellows?). I guess we should check with Austin and Karl. Could you shoot them a mail?

@lgray - yes, I've changed it to 1.2 mm according to an engineering drawing I have. Unfortunately, it covers only a middle part of the beampipe. I'll follow it up with Austin and Karl.

@ianna Does this overwrite #5880?

@fratnikov Yes, this supersedes #5880 (has correct beampipe thickness)
