Description
The cyclotron at TRIUMF was built in 1972 and commissioned to full energy in 1974.
The cyclotron vacuum tank is very complex with a total of 208 ports and a main double
seal 17 meters in diameter. The volume of the tank is about 100 m3 and operates at
2*10-8 Torr. The vacuum is achieved by cryopumping with internal cryopanels cooled by
a Philips B-20 cryogenerator and six cryopumps. A few vacuum problems related to air
and water leaks into the tank have been experienced recently. The troubleshooting
techniques, details on the leak size determination and leak localization are described.
