Window Pressure Test Setup
- Investigating the possibility of using Larson glass to metal seals as a means to couple metal windows to glass target chamber.
- Pressure test setup was assembled at UVa to test glass to metal seals at typical target cell operating pressures.
- Initial test on a Larson CP-100-T Pyrex glass to Copper metal seal (1-inch O.D.) performed on Nov 16 & 17, 2001. Test piece was pressurized to approximately 10-atm (137psig) of argon for 24hrs. The glass to metal seal did not explode. Although, 10-atm is low (typical target operating pressure is 12-atm to 13-atm). No leak tests on the seal have been performed during this initial pressure test.
