*After replacing all o-rings withing the spark plug array, the leak rate was still at the unacceptable level of 26mbar/hour. Using the helium leak detector, three large leaks were found at the halogen and noble gas solenoid as well as the vacuum pump solenoid.
*After replacing all o-rings within the spark plug array, the leak rate was still at the unacceptable level of 26mbar/hour. Using the helium leak detector, three large leaks were found at the halogen and noble gas solenoid as well as the vacuum pump solenoid.
*Once the gas solenoids were tied together and the vacuum solenoid was plugged, the leak rate dropped to 0.1mbar/hour.
*Once the gas solenoids were tied together and the vacuum solenoid was plugged, the leak rate dropped to 0.1mbar/hour.
*A ballcock valve has been placed inline of the vacuum pump as a cost effective alternative to replacing the vacuum solenoid valve. The order form for said valve can be found here [[media:CCorderForm.pdf|Bürkert]]

*We have received argon gas from Air Gas and have ordered F2 (5%in He)through Spectra gases.
*A new halogen filter has been purchased from Coherent Inc. (p/n:261068; $280)
*Lattice Electro Optics will be shipping new lens during the week of 4/5/2010
*A fluorine resistant regulator will be purchased by the first week in April.
