Introduction Introduction - Show design satisfies requirements
- Show design was validated through testing and prototype
Fabrication Summary
Design presented is part of 12 GeV Upgrade Project at JLAB - Requires 10 each 100 MV cryomodules (C100)
- Requires 80 cavities (7 cell, 1497 MHz, CW)
- Production schedule spans FY09,10 and 11.
Original design used Titanium Helium Vessel New design uses Stainless Steel Helium Vessel
Helium vessel design was validated by: Helium vessel design was validated by: Thermal shock in liquid nitrogen & leak check of braze joint (x3/joint) VTA cycle to 2K (x2/cav) Thermal cycle to 2K in HTB (x1) Pressure test of “Helium Vessel Head Test Fixture” Note : HTB is the Horizontal Test Bed – a facility for testing up to two cavities with cryomodule boundary conditions
HTB test verified that the design meets the requirements The SST helium vessel is easily fabricated using standard machining, welding and brazing techniques The SST helium vessel has significant cost savings versus the Ti design
