1.1.1 Installation Requirements
Feedthrough . . . . . . . . . . . . . . . . . . . 2 pass water with coax connector
2-3/4" ConFlat® Flange - IPN 002-043
1" Bolt - IPN 002-42
Other . . . . . . . . . . . . . . . . . . . . . . . . 1. Customer to provide vacuum-tight braze
joints or connectors for the water tubes.
2. XIU or Oscillator designed to interface with
the specific deposition controller.
Water Flow Rate. . . . . . . . . . . . . . . . Minimum water flow 750 cc/min, 30 °C max
Coolant should not contain chlorides as
stress corrosion cracking may occur. If the
water tube passes through a cryoshroud,
drain the tubes if the water flow is stopped for
any reason.
CAUTION
Do not allow water tubes to freeze. This may happen if the
tubes pass through a cryogenic shroud and the fluid’s
flow is interrupted.
